Yes. It’s rated for 120 psi. And yes I already did the calculations and came up with similar numbers. Thx. Now I wonder if this is a key to increasing pressure?

Wow. I’ve never considered just shutting off everything to let the line fill up. Maybe that’s the answer? All of that pipe - a mile - with 4000 gallons a day trickling in - would eventually fill the pipe and the water could escape out the source or out an air spout. I was told the back...

Yes. Last first. The spring produces about 3 gpm. 20 psi at house is what I meant to write. At no point along the route are either pipes full. The system provides continuous water - about 4000 gallons a day for the upper spring alone. So the water is slowly entering pipe from barrel but...

My thought is the lower spring might not travel on its own all the way because it has to go uphill a bit. The upper spring travels straight down before reaching the long level run. It forces the water through - I think after a few days worth of buildup in line. I have a few “see through”...

Thanks for thorough response. The tank is an offshoot. And the pond doesn’t supply water to house. It is also an offshoot of mainline that allows water to flow out once the house lines are full and not being used. In other words - the pond is a place to always allow water to flow out -...

That’s a good response. I think you’re right that the air from line two can’t totally escape. I can’t change the input sources as the springs are located where they are at. But do you think installing a vertical air lock relief valve near the highest point after the pipes join would help...

I think there is a negative or counter active pressure- causing restricted flow. Air can escape on both ends of run. But my thought is that the difference in elevation of the second spring is causing problems because it enters main line and goes uphill a bit. The water wants to travel the...

The main spring is around 4400 ft elevation. The house is around 4150 ft. The tank is slightly above house but is not part of the continuous run. It fills if I open valve off main line. The second spring (that I recently tapped) is at base of hill around 4200ft. More volume and...

Yes. Sorry. I meant the flow at source is quite low but once down hill it has about 20-30psi. That pressure is pretty steady at bottom of first steep hill. But friction and a mile of pipe reduces pressure so that it’s about 10-15 psi at house. I’ll draw diagram when I get home. The...

How did you find PF?: Google I have an off grid home that uses a spring fed gravity flow water system. The spring is about 200 feet up a steep mountain- and very low flow. The pipe run starts at 2” pvc and eventually is 1.5” pvc. Once down the hill the water flows about 1 mile down an old...
