Plumbing question

[_Mephitus]

This may be an odd thing to post, but im out of ideas short of calling a plumber. But my kitchen sink wont drain (standing water). See the diagram i sketched up. I have first ran draino, it helped it from standing water to VERY slow drain. So slow, it takes hours for a full sink to drain. I took apart the trap (clean). and snaked the X'ed. Now its back to standing water. The washer is draining on the same line and has no problems, so i know it can't be the primary drain outlet. So i mcguyvered my hose to plug the drain past the trap since we have above average water pressure (70+ PSI rather than standard 35-40) and i figured i could just "blast" the clog out. The hose drained clean into the drain for a good 4-5 minutes without issue or backflow anywhere else in the house or roof. As far as i could tell, the drain was clear. But yet when i hook everything back up, its still standing water!

Ideas?

Can you get up on the roof to check the vent? Maybe it is blocked, use a snake on it and see what happens. Such a problem wouldn't cause THAT severe of a problem, but it is worth a try. WAAY off topic. LOL.

Sadly, I don't have a snake long enough. (only about 6' long) Though wouldn't that cause a draining problem for my washer too if that was the issue?

Yeah, but 6' is better than nothing. If you have a long enough hose, you could also use water, since you have good water pressure. The washer usually has a pump to PUSH out the water, The sink only drains by gravity, assisted by the vent.

Get the heavy duty Drain-O or something a bit stronger for plugged drains and try a few more times. Once it does start draining a bit you may need to put very hot water through the pipes for a time and then try the clog clearing stuff a few more times.

A longer snake would be better as you know. Any rental places in your area to get one for a few hours or a day?

I'm sure your drain woes are fixed by now.

We had a bar of soap fall into the toilet once and couldn't get it out nor get the toilet unstopped. I think the liquid product we used was called Drain Eze. It worked very well. I had to drive like 10+ miles to go buy it, passing up other home improvement stores, but it was well worth the trip.

I eventualy had to put an entire 80oz bottle of prof grade Drain-O in there and let it sit for over 6 hours before it degraded the plug enough to start draining. Wild and crazy though...

When I first read (skimmed) your last post, I had to do a double take since I thought I read that you had to put 80 proof Draino down the drain. I've got to start paying attention.
