SUMMARY

The forum discussion outlines an effective four-step home remedy for unclogging drains, specifically targeting hair ball clogs located about two feet down the pipes. The method involves pouring 2 quarts of boiling water, followed by 2 cups of Drano (either gel or liquid), then 2 cups of bleach, and finally another 2 quarts of boiling water to flush the system. This combination has proven successful for multiple users, providing a cost-effective alternative to professional plumbing services. Caution is advised regarding the mixing of chemicals, particularly the interaction between Drano and bleach.

PREREQUISITES
  • Understanding of chemical interactions, particularly between sodium hydroxide and sodium hypochlorite.
  • Familiarity with common household plumbing issues and solutions.
  • Knowledge of safe handling and application of commercial drain cleaners like Drano.
  • Basic skills in using plumbing tools such as plungers and snakes.
NEXT STEPS
  • Research the chemical composition and safety guidelines of Drano and bleach.
  • Learn about alternative drain cleaning methods, including the use of enzymatic cleaners.
  • Investigate the effectiveness of mesh strainers for preventing clogs in drains.
  • Explore professional plumbing techniques for dealing with severe clogs, including augering.
USEFUL FOR

TL;DR
home remedy for hair and other clogs in drainage piping
4 step sequence:

1. 2 quarts boiling water down the sink or tub drain. Boiling: 220 deg. F., not just hot. Softens up the clog. Then add
2. 2 cups (16 ounces) Drano (gel or liquid, commercial drain opener). Wait one full hour to let it work. Then add
3. 2 cups (16 ounces) bleach down the drain. 'Double whammy'! Wait another hour for that brew to work. Then, finally, pour another
4. 2 quarts boiling water down the drain. Flush well after that.

This has worked twice now for me for difficult hair ball clogs located about 2 feet down the drainage pipes. Each of these methods was recommended to me as an individual solution, but only by combining them all into one process, have they now proven most effective. First 2 times, anyway, on a sink and a bathtub backup. So, you may want to try this method first in lieu of a $700-plus Roto-Rooter visit and inconvenience from the plumber, when using a plunger just doesn't unplug a clogged pipe.

What does the bleach part do? Just curious.

Also, did you do this after trying to snake the drain and that did not work for some reason?
 
Not sure what the bleach does, exactly, but someone recommended it to me one time, and I tried it. It worked OK, about like Drano works. OK, but not great. I really can't explain any 'double whammy' effect, though. It just sounded good.

Well, I draw the line on augering, using the snake. I work a lot still in an old apartment building with old pipes, and I will change out drain piping, P-traps, everything under a sink, but I draw the line at augering the line when it goes into the wall and down a drain pipe. The clog usually is located there. I just never got very good at snaking, although I have tried. I have a good plunger with a smaller diameter inner suction cup that seals pretty well on small drains, but I don't snake anymore. Pros use a very expensive, motorized unit.

So, I use the plunger first, then this new liquid method, then, lastly, the snake (or, rather, call the plumber with the snake).

One-and-a-half, at most. As far as I've just looked up Drano also contains sodium hypochlorite (bleach).

What I would suggest you is some fine mesh strainer plugs.

Is it safe to "mix" Drano with bleach in the pipe even after an hour? Shouldn't there maybe be another boiling water step in there before?
 
Thanks. Yes, I always tend to exaggerate. Also, thanks for the mesh strainer solution. The best solution! I have recently bought the most expensive ones at Ace Hardware in U.S. The all metal ones work pretty well for the bath/shower drain,

but these I find work best:

They have an additional, removable rubber filter in the middle, which seems to catch even more. The middle area drops down into the drain hole too (can't see this in photo).

On the question of an additional flush between Drano and bleach, yes, perhaps needed, not sure, but I have left Drano in pipes for very long periods of time, forgetting what I had been doing, and, in my experience, anyway, I don't think the Drano or bleach has damaged the pipes' interiors very much, so far, over many years of Drano being used. They say it does damage them, though, I know that.

Most likely, yes**. I assume "chlorine" bleach, which is alkaline in order to keep the bleach stable. DO NOT MIX CHLORINE BLEACH WITH ammonia, urea nor with acids. Possibly other materials not to mix it with also.

** WARNING: I may be highly mistaken about parts of what I said about to mix or not to mix. Drano is more than just sodium hydroxide in water. See the wikipedia article and consult with your own local experts. See in https://en.wikipedia.org/wiki/Drano .

I have used "drain centipede" and I would if I could maybe also try one of those plastic flexible sticks with the hooks on them; for bathroom sink drains. Also I often use a plunger.

Drano already has bleach in it, so it should be safe. The main two ingredients in Drano are:

Sodium Hydroxide - The strong base that eats up the clog.
Sodium Hypochlorite - bleach, which apparently bleaches organic matter and provides more 'cleaning power'.

Good work, @Drakkith.
I still say, people, check the wikipedia article about Drano, and find advice if needed from your experts.
