A few years ago, I had a side gig as the temporary maintenance man at a downtown Asheville condo building, and the one problem that constantly came up was clogged or slow drains, especially in the shower.
You know what it feels like:
You're taking a quick shower and suddenly the water is up over your knees, and you wish you'd brought your hip waders.
Fortunately I found a cheap alternative to calling a plumber...
The Zip-It Hair Snare
Basically it's a cheap, disposable plastic version of the plumber's snake. It kind of reminds me of a zip tie, except that it has teeth.
You stick it down into your drain and pull it back out, and some of the hair that's clogging the drain will get stuck to the little teeth and come out with it.
If you're doing this in a bathtub, it will be easier if you unscrew the drain cover first.
Repeat this several times, and you're done. Look how much stuff comes out!
I recommend also getting a pair of gloves and a little bucket to catch the goop, because the hair clumps are kind of gross. But hey, it beats calling in the professionals. During my maintenance gig, I bought a dozen of these for the property manager and cut the number of service calls way down.
If you try this and it doesn't work for you, shoot us an email. We don't do plumbing, but my wife has a "little black book" with all of the best craftsmen we know.
