This is becoming a too frequent issue. The hand tightened white plumbing connection to the drain pipe that came with the disposal loosens up, slides down and leaks and sometimes we have the whole beneath the sink splattered with water and debris.
I have been to several local home improvement stores and the responses have ranged from that should not happen to just a deer in the head light blank stare to aiding in the training of new associates with the age old ---"sir, I do not work in this department, let me get someone who does".
My thoughts? The plastic drain piece coming out of the garbage disposal curves down as I guess it should (not an expert on disposal plumbing anatomy) but that is it ---it curves. It has never been cut to shorten the length and in my opinion the end I slide the drain pipe on should have more straight length. Because there is very little staright portion to slide the drain pipe on the drain piple hand tightens curve of the garbabe disposal drain. The other thought is the garbage disposal vibrates and vibrates the hand tightened piece off and voila yukfest underneath the sink.
I really want to add an exentension to the garbage disposal drain and glue the extension on. BUT-----that means glueing and dealing with the very sharp curve in the garbage drain pipe. Lookforward to your help.
Thanks
