In reply to the discussion: Is there a drain opener for the tub that won't cause problems? [View all]Kleveland
(1,257 posts)We have a very old house, and were calling plumbers once a year to snake.
It was getting too expensive, and a power snake can damage pipes, as can caustic drain cleaners.
We had to sign a waiver last time, and our neighbor a few doors down had her pipes damaged by the same plumber. She needed new pipes put in, which means wall or floor demo, and $$$.
We tried this stuff.

Also used a plunger.
Keep in mind, you have to plug the overflow valve in a tub to use a plunger, or it won't do anything. You need to create a vacuum.I used a very wet wash cloth, and held it tight over the overflow slots.
Our sink and tub meet at a common point, so the sink affected the tub. The clearing started to clog the tub, so I used a plunger there, and it all came out in the tub, was really gross, but it wall worked out.
I did a detailed review of the process about a month ago on Am at the product page.
You need to treat every motnh or so. The buildup is usually soaps cum and stuff, not just hair.
We have also been using a cheap $3 plastic snake in the tub to pull out hair buildup. Got ours at H Depot, but Am has something similar.

This problem has plagued us for over 10 years, but I am confident we will never have to call the plumber again!
This enzyme stuff is the best $10 we ever spent!
Good luck, and stay away from caustic drain cleaners!
