Hi all,
Problem: My kitchen sink drain VERY slowly...it has taken about 5 minutes to drain fully sometimes. My home inspector informed me that I have unvented 's' traps in the kitchen and bathroom. I have one main roof vent, which is too small according to the inspector, and the bathroom plumbing and kitchen plumbing are on opposite sides of the house.
Here's what I have tried:
- Drain-o, industrial strength gel, commercial liquid "green"
- Removed the pvc pipes and augered the drain from the kitchen 25ft. and very little was removed.
- Used a garden hose and "jet blasted" the kitchen drain pipe to try a pressure cleanout.
My kitchen piping is 1 1/4" pvc with a dishwasher.
I considered the following:
- calling a plumber (I know it sounds funny, but I want to use this as my LAST option)
- removing the pvc drains, and replacing it with 1 1/2" pvc pipe AND an Oatley Autovent.
- Reaugering from the kitchen and the basement in both directions.
Does anyone have opinions/suggestions. I know I posted something similar before about this issue, but I've tried a few things since then...
Thanks for the help.
