Hey guys...great site. I have looked for my answer but my situation doesn't fit any others I could find. In fact I may have two problems with the same line. I will provide as much info as possible anticipating likely questions I have seen on other post.
Symptom: Kitchen island sink p-trap gurgles sometimes and bubbles others...facts below...
1993 built on slab, I purchased 6/07
On the side of the house in question I have an island kitchen sink, a toilet, a utility sink, and the washer drain.
I can't say if the island is vented properly but the vents (on that side of the house) I see are a 2" (3"?) directly above/behind toilet and a 1.5" located centrally between the utility sink, washer drain and island sink.
FYI...the other side of the house has a 1.5" for each sink a 2" (3"?) for one toilet and a huge (4"?) centrally located above another toilet.
Troubleshooting:
Utility sink use has no effect on problem.
Kitchen Island sink gurgles after use almost a drip drip drip sound..very consistent. Viewing water in the trap I see the level drop as the sound is made. Also, after this gurgling sound I can hear the pipe filling (you know the sound) when I run water again... then it gurgles again if the sink is run a fair amount. No sewer gas smell. OBTW, same sound when dishwaser drains through same line.
Island sink trap water bubbles up when clothes washer drains. No change in water level (just air?). Slight smell if any.
Island sink trap bubbles when toilet is flushed. Again, no change in water level and slight smell if any. FYI, we have discontinued use of the toilet as I think I could be taking a growler in my kitchen sink....lol. I really think it is air but still.....forcing toilet sewer "air" towards my kitchen sink limits my appetite.
To be clear the "bubbling" is not small bubbles. They are large and very loud. The trap water returns to its former level after they work through.
My 2 cents
1- I think the p-trap is draining when I use the sink and it gurgles (siphoning or excessive slope???). How can I verfiy this and/or fix it?
2- I think when the washer and toilet drain there is air trapped downstream in the drain line and the first(only?) place for it to go is up the sink line. Why not the vent line (clogged?) Improper/poor design? How can I tell the difference?
I waited to post this gathering information I thought you all would need. Please help!!!
Thanks in advance!!!
