Quietly Pump Water 11ft - Ideas for Sump Pump Solutions

[gloo]

I was going to say that there are these manual cranking water pumps that are quit quiet when i crank them to pump. too bad there isn't some quiet motor that I can use to run it (timer based?).

http://www.princessauto.com/pal/en/Manual-Barrel--Hand-Pump/Rotary-Hand-Pump/8334104.p

Does anybody else have something creative?

 

[gloo]

Oops, well, fortunately my answer happens to be the same.

Amazon lists the entire product line of a particular pump and the max head of any of them is 10'. So no, they won't work.
https://www.amazon.com/dp/B0027J67GS/?tag=pfamazon01-20I don't see what value a timer would add, but whatever the case, if he gets a smaller pump it will have to run more often, not less often.

So Russ, you know the most about regular sump pumps I guess ( as well as Goest). From what I have learned to get the quietest sump pump going do the following:

1. Get a low velocity pump (Goest suggestion) - does this mean 1/4 hp is quieter than 1/2 hp?
2. Make sure the sump pump is sumbersible and high quality cast iron that is oil primed
3. Use rubber hose if possible to reduce virbation
4. Use sponge or material between pvc pipe (if not rubber hose) and floor joist and sump pit walls
5 Insulate floor joist using sound proof insulation
6. Should I build an enclosure room with sound proof insulation?

I have found a range of external pumps (also known as inline) that have lifts as high as 18 feet. (course, it's 240V)There is a 110V pump with a 13.5' lift:

SUP02722 -1200-gph w/18' cord - 6.5 x 3 x 5.5 (Model 12)
110 watts; 1.5 amps. 880-gph @ 3'; 580-gph @ 10'; max lift 13.5'.

And it's magnetic, so it should be quiet.

How does this work? Does it have to be submerged? Or just one end of tubing in the water.

And what about priming issue? I guess the timers have to come in play or it will burn out?

 

[Danger]

I am fine with the noise... my wife less so. But when her parents come to sleep over, they are not thrilled to say the least.

Dude! You're sitting on a gold mine! Do you have any idea of how many guys want their in-laws to be too uncomfortable to stay?

 

[DaveC426913]

How does this work? Does it have to be submerged? Or just one end of tubing in the water.

External or "inline" pumps are designed to work while out of the water. Just stick the inflow tube into the water.

And what about priming issue? I guess the timers have to come in play or it will burn out?

No. You're going to set the timer so that the pit never runs dry. That's the whole point of limiting how long the water pump runs for.

This also means you'll have to raise the sump pump a few inches, so that the pit never runs dry, and so the water pump always has some water to pull. Yeah, this could get tricky. If the sump pump drains down to one-inch, then the water pump kicks in and runs for 20 minutes, you'll end up running the pit dry and losing prime. The water pump can theoretically self-prime, but it won't if there's barely an inch of water in your pit.

One way to help the water pump flow rate as well as self-prime, is to put the water pump as low as possible, so the inflow tube is as shirt as possible. Sit the water pump on the pit floor. It will only have to draw a foot, which is good, and it doesn't matter if it's submerged part of the time.

But all this is why I think you'll be constantly fiddling with the setup.

Gloo:

1] How fast does the pit fill with water? How many gallons - in your estimation - are entering the pit each hour (if you shut the sump pump off)? We need to know this.
2] How high is your float? Can it go higher?

Hi gloo. This is a very good summary. I'd definitely recommend trying #3, 4, 5 and 6 before you put money into a new pump. Your existing 1/4 hp pump is relatively small and should work very well. Although it's new, you also should consider checking it for any damage by running it in the sump with the discharge pipe removed so it's just circulating water inside the sump to see if it's making any strange noise or vibration. But your list here is great starting point and I'd recommend trying those on your list first. If you're still having issues with the pump, I'd be interested in hearing from you.

so # 1 is true? higher hp means more noise?

 

[DaveC426913]

so # 1 is true? higher hp means more noise?

Surely, yes. And that was one of the my concerns. Many of the external pump (that like like a pool pump) are quite noisy.

The nice thing about the magnetic pumps is that they are virtually silent.

 

[Danger]

Okay... I'm going to go way out on a limb here, just because I'm at my wits' end.
This would be expensive and inconvenient, but just might possibly do the job if, and only if, you are correct about a hand-cranked pump being quiet. How about using a pneumatic or hydraulic motor on the pump itself, and mount the power system in your garage or out in the woods or some other place where you can't hear it?

 

[RonL]

Hi gloo,
I'm having a sleepless night, so looked at your problem and can't understand exactly why the noise with an electric sump pump system.
I suspect you have a typical system ? if so, does it get loud at the end of pumping the sump dry ? if yes, it might be cavitating air, this might be corrected by setting the float switch so that it shuts the pump off leaving a little water in the sump.
You mentioned a check valve at one point, a good valve at the pump and maybe a second check valve at the storm drain discharge point would lock the water column in the pipe thus preventing that water in the pipe from falling back into the sump.
A good two inch pump would make for a fast cycle time. All the sump pumps I have ever used have been very quite and produced a smooth water flow.

These are the only thoughts I have, best wishes

Ron

 

[Danger]

...looked at your problem and can't understand exactly why the noise with an electric sump pump system.

That's been bugging the hell out of me too, but since he's so adamant about it I just tried to overlook it. When I lived down east for 13 years, I had a sump pump in my basement and never once even heard the thing when it came on, let alone be bothered by it.

Yeah , if i had the time and was mechanically inclined, i would try to do this using some kind of timer. Unfortunately, i don't have the sophistication to try that. I also don't have a spot to house the motor.

@ Ron -- thanks for your input Ron. Yes, I am not that sophisticated in terms of sump pump knowledge. I have been asking around and researching more using the input given to me in this thread and I sooo appreciate the help and the concern from everyone. Some questions for you since you seem to be quiet knowledgeable about the subject:

1. What is the power rating of your pump? 1/4, 1/3/ 1/2? Q Goest in this forum mentions that 1/4 is quieter than a 1/3 or 1/2 because less power and velocity means less vibration
2. Yes, in terms of air cavitation, i don't think it sucks all the water out so that the pump is sucking out air (is that what you mean about air cavitation??). But what i do notice is that their is this weird sound after the water is expelled and the sump pump shuts off. It's like a some kind of air release mixed with water coming out of the back up sump pump pvc pipe that is attached to the main expelling pipe. What is causing this do you think?
3. Where should the check valve be optimally located?? Near the sump pump? Just before the vertical turns horizontal? What is the best type of check valve in terms of type or brand (heard something about spring based)
4. How can i coat the sump pump so that it doesn't rust?! Sometimes I think the sump breaks because it is cast iron and rusts out rather than motor issue.
5. What brand do you think is best for sump??

Thanks for caring Danger - I think the vibration part is better since i did a few things the last day or two..
1. I put some sponge around where the PVC pipe is touching the lip of the sump pit.
2. I will also wrap the pvc pipe the best I can with with sound proof insulation.
3. I will put some of the sound proof insulation up against between the floor joist
4. Maybe I can build an encasement room with insulation proofing.

More so now, I think the problem i need to address the is the air sound...like a weird air sucking sound.

 

[Danger]

Yeah , if i had the time and was mechanically inclined, i would try to do this using some kind of timer. Unfortunately, i don't have the sophistication to try that. I also don't have a spot to house the motor.

Well, to start with, a timer isn't needed in this instance because you can set the flow rate to whatever you want. In the case of a pneumatic system, the exhaust will be bubbles, so the only noise will sound like goldfish farts. If you go hydraulic, you need a return line which adds significantly to the cost but not the complexity.
For coupling the motor to the pump, I'm quite willing to bet that if you take both to your local automotive repair shop, the mechanic will be able to mate them up in short order and at a fairly low cost. (That's up to him/her, of course. If you have one who is also a friend, he might do it for free... which in my culture means that you have 6-pack waiting when he arrives.)

edit: You made your last couple of posts while I was composing this one. I wasn't ignoring them; I just didn't see them until now.

More so now, I think the problem i need to address the is the air sound...like a weird air sucking sound.

I once got divorced over that very issue...

LOl...oh man, I am not going to ask you to expand on that one Danger. I am about to post a video in a bit which should show the pump and you should be able to hear the sound. The motor sound is something I can tackle now with some insulation (i really really hope). But the air sucking sound seems more prevalent now.

I wish i can just find a really really slow quiet pump that can run for a certain period...one that is pump just slower than the rate at which it comes in. I still need to measure the flow rate. My problem in measuring the flow rate which guys like Russ Watters, DaveC and Goest are asking , is that the water comes in slower if i suck the pit all the time. MOstly it gets backed up around my house in the weeping tiles; whenever the sump pump goes, it will suck up a certain amount, but fills up quite quickly cause it is being filled up with backed up water in the weeping tile system. So what is the real rate?? The one that is measured with filling sump pit with backed up water; or the the rate if I constantly pump out the pit and don't let the weeping tiles fill up??

 

[Danger]

Hey, now! You never mentioned that part before. You just put this onto a whole new playfield. I'm not really familiar with the specific aspects of it since I live in a place where I don't have to deal with it, but... could you perhaps install an auxiliary pump with the intake in the weeping tile conduit rather than inside your house?

Sorry Danger, I don't know how this auxillary pump would work versus just pumping from the pit? How would this pump run? Self priming or not self priming?

 

[gloo]

Here is a youtube video of my pump and how it sounds at the end. I figured out the air sucking sound at the end of the video is coming from the back up water pressured sump pump. If I shut the valve off, the air sucking sounded that echoes is not heard. But I can't turn off that valve else I may get some kind of disaster if it starts to try to pump water out. Maybe what I can do to eliminate that air sound is run another pipe attached to the back up water pressure sump discharge pipe, further down?? Or maybe because it doesn't have a back flow valve and the sound echoes down the discharge pipe? If anyone can guess from the video...please comment.



The sound is actually quite more noticeable upstairs in the bedrooms so don't think that the video noise is that representative.

 

[DaveC426913]

So what is the real rate?? The one that is measured with filling sump pit with backed up water; or the the rate if I constantly pump out the pit and don't let the weeping tiles fill up??

Presumably, if you get a system going to pump more efficiently, then you will be dealing with the second scenario. So that is the one to consider.

 

[Travis_King]

That sound your hearing sounds like your pump sucking air at the end of the cycle when the float drops down to it's terminal level. Also, while shutting down the impeller will be slowing, so water will no longer travel up the pipes, it will just slosh around and mix with whatever water is flowing back down the line between the pump and the check. If there's a way to adjust the float so that it shuts the pump off with the water at a slightly higher level, that should be eliminated.

Are you saying that you are always running your backup pump? It's there as a backup in case you lose electrical power. You'll definitely get constant noise if you've got water running through half the pipes in the house all day. It takes a decent amount of water for that venturi system to work, so you'd hear it. If the backup is running, turn it off.

third, I'm pretty sure you've got check valves. Those red handled valves look to me like combination ball valve / swing checks. (see here: https://www.plumbingsupply.com/pvccheck.html). Also, I couldn't tell because you panned quickly, but where the pvc turns to the black (pvc?) there are two hose clamps. Are those just to join the pipes? Or is there a small section in there with a fitting? That could be a check as well.

I can't tell what's going on with the main sump, I see a valve on the far right line, is that the main discharge line? then there is a wye that goes back into the sump, what's going on there? why are there two lines coming out of your main sump?

To help answer some of your questions:

1. What is the power rating of your pump? 1/4, 1/3/ 1/2? Q Goest in this forum mentions that 1/4 is quieter than a 1/3 or 1/2 because less power and velocity means less vibration

The power required is determined by your specific flowrate and head requirement.
Look, there won't really be much of a difference in the motor sound between 1/4 or 1/2 horsepower. The velocity of the fluid may make some noise, sure, but I really can't see that you'll be able to change it enough that you'd notice. This system will make at least a little noise, it can't be helped. The bottom line is that you'll either have a large capacity pump which drains the system quickly, but then has numerous start/stops every day, or you'll have a smaller pump that runs a lot longer during each cycle, but has less start stop cycles. There's no way to significantly increase the amount of time between cycles while the pump is off without making the sump larger. You could look into changing the high level switch point on the float switch so that the sump fills up more between each cycle, but if and by how much you can do this will depend on your specific pump and switch.

3. Where should the check valve be optimally located?? Near the sump pump? Just before the vertical turns horizontal? What is the best type of check valve in terms of type or brand (heard something about spring based)

Like I said, I think you've got them, but they should be close to the pump; I'd say at least a foot after the discharge of the pump.

4. How can i coat the sump pump so that it doesn't rust?! Sometimes I think the sump breaks because it is cast iron and rusts out rather than motor issue.

Buy a plastic one...but in all honesty the cast iron ones are designed like that for a reason. They're sub pumps, they're meant to work in water, a little rust is ok.

I'd say a contender for the issue is a lack of sound deadening / insulation between the basement and the floor above. Also, you've got the pipes supported on joists, so those vibrations (no matter the flow rate you put through those pipes) are going to transfer through the home. In some places they may even reverberate in hollow spaces and become more noticeable. If you can somehow isolate the pipes from the joists (somehow support them from the foundation) I think you'd notice the noise less upstairs.

Hi gloo,
After watching the video I feel that the ending cycle is a little like I suspected and having an effect on a check valve in some way. It looks to be a well designed system and two things pop into my mind, plumbing codes and system compatibility.
In the interest of maintaining house value and possible insurance coverage, as well as possible plumbing codes I think you might be wise in consulting a qualified plumber or local company that can say what is best for your system.

I'll wait and see what a few others say before going further with what I think.

Travis - no the back up pump has only ever been used once...but that is where the water sucking sound comes from at the end of the video. It doesn't have a check valve, it has only a shut off valve (the one you mentioned with the red handle), I don't think that has a check valve with it. When that valve is shut off...it prevents the sound from occurring. Do you think a quiet check valve would prevent that?

Two lines come from the main sump pit: the main sump pump and the back up battery powered electric sump pump. That one is ultra quiet...wish that one could run really slowly.

 

[Travis_King]

Ok, good. But first off, close the valve on the venturi system if it's not in use. That will prevent that from happening. If that noise came from the backup line, then likely as not you're getting some water hammer. when the main pump shuts off. That valve should be closed until you have to use the backup system.

You are right about the valve on the venture system as well, it looks like a standard ball valve. I don't know where you are living, but if this line doesn't have a check valve, you should check to see what's at the connection to the main. There should be a backflow preventer somewhere in this system to ensure that if the main suddenly loses pressure, you don't suck up sump water and contaminate the main. That's up to local code though, if the community main is protected against your house, then it may be ok to leave this as is. I'd ask a local plumber or your water authority on that one.

How does the battery backup run? Is it an automatic backup with it's own float switch (I would assume it's float would travel significantly higher than the main pumps float, so that it would detect when there's something wrong with the main pump) or is it a manual thing? Either way, leave that valve open, and I'm almost positive that that valve is a combination check and ball valve.

Is there a check valve on the main sump pump? Is it that piece with the two hose clamps that I mentioned?

I think there is a backflow valve on the main...I am going to have to ask a real plumber...I would not bet my life on it. The batttery back up runs like you said. I really don't think that is a combo shut off and check valve, I remember playing with something that looks exactly like that and it only gets blocked if you swing the red handle to the shut off position. All I know is that when i turn that shut off valve to shut, the air sucking sound is gone. I can't afford to leave it shut cause one day, if it does run, it will be a disaster and flood my basement.

Gonna have to get a plumber to fix a lot of things...just don't want to get rapped on the price. They are just rip off artist trying to charge like 100 bucks an hour for labour.

 

[Travis_King]

Ok, it's not a big deal. I would imagine it's there, but maybe not.

The batttery back up runs like you said. I really don't think that is a combo shut off and check valve, I remember playing with something that looks exactly like that and it only gets blocked if you swing the red handle to the shut off position.

Ok, but correct me if I'm wrong here: Look at the two valves (the one on the venturi, and the one on the battery backup line). On the venturi line, youll see that there's the middle section where the handle is, then there's two identical connections on either side, right? On the battery backup, take a look and you'll see that there's a longer section at the bottom, and it looks asymmetrical. That is the combo style that I linked to in the other post. On the bottom there's just a hole, a void with a ball in it, and that's it, when the water is flowing up the ball is raised by the pressure and the water flows around it. When the water stops, the ball falls into the hole, clogs it, and the water can't get through. Can't get much more silent that these types. I'm pretty sure that's what it is, otherwise your main sump would simply flow right back down through that line. oo)

All I know is that when i turn that shut off valve to shut, the air sucking sound is gone. I can't afford to leave it shut cause one day, if it does run, it will be a disaster and flood my basement.

which valve are you talking about? The battery pump's valve, or the venturi's valve?
Like I said, either way, close the valve on the venturi line until you actually have to use it. It's not an automatic system, so you'll have to have a procedure for starting it up in the event of power loss anyway, right?

As before, I'm outta here. It's way over my head (just head, mind you, not pressure head or anything else related to this thread.)

Ok, it's not a big deal. I would imagine it's there, but maybe not.
Ok, but correct me if I'm wrong here: Look at the two valves (the one on the venturi, and the one on the battery backup line). On the venturi line, youll see that there's the middle section where the handle is, then there's two identical connections on either side, right? On the battery backup, take a look and you'll see that there's a longer section at the bottom, and it looks asymmetrical. That is the combo style that I linked to in the other post. On the bottom there's just a hole, a void with a ball in it, and that's it, when the water is flowing up the ball is raised by the pressure and the water flows around it. When the water stops, the ball falls into the hole, clogs it, and the water can't get through. Can't get much more silent that these types. I'm pretty sure that's what it is, otherwise your main sump would simply flow right back down through that line. oo)

I will just have to ask a plumber what is what as I plan to redesign this area. In terms of which valve i shut off to quiet the noise it was the Venturi side.

Thanks Travis.

Is the venturi system on an automated control? Or do you have to turn on a valve on your water main? If the system kicks in on its own, then yea you have to leave it open. However, if it is truly a system for when the power goes out and the battery backup is down, then there should be no reason to have it capable of running while you are home. If you want to run that pump, do you have to open any valves or anything?
