I have a double kitchen sink in
which the water will just not go
down. The wife insists she didn’t put anything down it. Water flows readily between the two (it all flows to the right when the In sink erator is turned on in the left basin – then equalizes when ISE is turned off). I have tried a professional strength liquid plumber, but all that did was add to the level of liquid in the sinks. I tried a plunger, even dualling plungers but they seemed to do no good. What should I do now?
