Does anyone have any recommendations for a plumber for the house?
I have some simple slow drain issues, but the wife also will jump on any opportunity to remodel anything in the house.
If you think it might only be grease or clotted detergent, run the hottest water you can down your slow drain.
follow with a bit of cool water and draino, repeatedly.
Dont pour hot water in the same time with draino because it may react violently and you get a face full of draino.
Let it get down a bit before resuming the hot water.
If it's solids, you will need an auger (like roro-rooter).
Slow drain might also be lack of air coming in the vent pipes on your roof, but that's usually accompanied by a sewer gas smell.
