I had to replace all my water lines and bought my supplies from Warren Pump. They did give me a really good deal on my water lines, but after I fixed my lines, I still had a leak. To make a long story short the coupling they sold me was defective. I took it to them and they said my water must have corroded it. If it could do that in just one weeks time, I think my drinking water would've killed me by now. Anyways after a period of 3 months or so they finally reimbursed me the coupling price and half my water bill.
