Don't do what I did lately, and hire a handyman who has plumber skills.
The whole idea was to save some money on clearing the drain my washing machine empties into. So the guy snakes out that line, but can't get far down it, so he goes down the other two access points there (I have three bathrooms), and gets a bunch of root pieces out of the pipe.
Took him a little over an hour, and he wanted $270. "It's $90 per snake", he says...
I didn't get mad, but he could tell I was shocked by that price, and not happy, so he amends his first price saying "Well, if you can pay in cash, I'll drop the price to $160".
What a rip-off; I could have bought a snake for that price and done it myself.
