Cover your backside coming and going with these guys. They will sell you what you want at top dollar prices. I once asked how to do some plumbing work they were more than happy to tell me but what they failed to tell me was that it was no where near the right way to do the work nor was it close to the state plumbing code. Also some of the material that I bought was defective so I took it back to them and they said they would sell me another one and there was nothing they could do about the defective part.
