i've just installed a double-bowl kitchen sink as well as a garbage disposal on the left side of the sink. i've hooked up the dishwasher to the garbage disposal. in general, i've used pvc pipe from the p-trap through to the drain pipe in the wall. however, i used a kit (plastic, but not the same thickness as pvc) to connect the disposal to the right side of the sink, and to the p-trap. i have two leaks -- at each end of the horizontal pipe connecting the garbage disposal with the "t" (?) on the right-side sink. the disposal side fits snugly against a rubber washer. the other side is screwed onto the the "t" pipe. both sides drip, with the non-disposal side dripping more heavily. any ideas? get rid of the kit stuff and replace it with pvc?

I realize that this is the plumbing forum, but I thought some of you guru's might be able to help me with this one. Okay, so i attempted to install corrugated drainage lines in my flower garden in the front of the house in order to divert rain water coming from a down spout right in the middle of the garden. I needed about 30' & dug my trench 1" deeper for every 10'. Once I got all the drainage lines in the trech I put the garden hose in the down spout at the roof line & waited to see it work. No good. I had leaks at every joint. I checked to see that I had the fittings as tight as they could be, and they were. But everything continued to leak. I need some help. Are there any tricks I don't know about? Are you supposed to use any kind of glue or cement at the joints? Is 1" for every 10' sufficient? Help -Bill
