Ok, I am going to try to explain what my husband is doing and how/why he is stuck but it may be hard since I am neither the brain nor the braun in this project. I convinced him to install a Delta faucet with a pull out sprayer. Everything was going ok but then he had to either add or replace (not sure which it was ???) shutoff valves. Our home is apx 21 years old. I *think* he only had to replace them, but could be wrong. Anyway, the connection that came with the faucet did not match the old shutoff valve connection so he had to go to the store to buy a "Angle Valve for Wall Pipe." So keep in mind he is working on a connection that is very close to the wall and he can't move it like I've think I've seen in some of the pictures I've looked at for this project. Husband put the shutoff value on pipe and then tried to screw the compression nut onto the shutoff valve with several types of wrenches -- an adjustable wrench was the main weapon of choice. We had massive leaking. We thought maybe it needed to be tighter but the end result is that tightening this connection has led to a warped other connection. Hmmm...trying to explain this but since I don't know what I'm talking about it is hard. I think after husband puts the shutoff value on then he has to connect a tube to that -- but the part that he connects the tube to is now warped. Husband can't understand how he could have tightened the connection tight enough without causing this problem (after trying to tighten for a long time with adjustable wrench, he went to Wal Mart and bought several scary looking wrenches). One side is now tight -- no leaks. The other side is still slightly leaking. But the side that is tight without leaks has a warped connector. Oh, and the unit he bought came with this small thing that *might* go inside -- hmmm, is it washer or ring of some sort?. Husband wasn't sure if he should put this in but opted not to because the way it was shaped it sort of is pointed (raised?) and when it fits in it does not sit well against the part that is inside the other -- also sort of pointed (raised?). I'm sure I've lost you with this one. But if you might know what I'm talking about, husband wants to know if the little thingie that came with the value is supposed to be used (I think he read in one place that it all depends). So my questions...1) how to tighten the connection for the shutoff valve without warping/stripping other connections...2) how tight should it be (super tight or do we do overkill?)...3) does the little ring thing go inside...4) is there something were supposed to put on this connection to stop it leaking? Thank you so much if you managed to read this! Poor husband went to bed feeling very down (and tired). Kids want their daddy back. I can't stand to see husband bang his head anymore! Husband has been to hardware store 7 times today! ~Rondi~

reply to Ragnar;I had previously dumped water down the main before installation&it seemd to drain fine. Thanks for your input.Please!respond again.
