So I just moved into an older trailer I replaced about 2/3 of the water supply lines underneath it due to bursting and bad leaks I replaced with mostly pvc where I could get away with it. I have good hot water pressure to the shower and sinks and now there's barely any cold water pressure? Any clue as to what to do next because I'm stumped. Thanks. Luigi

Hi Luigi..

I have a few ideas here, but first I want to know if you used PVC pipe on any hot water lines.. Not allowed...

Let me know...

We know you have good cold pressure at least to the water heater or else you'd have bad hot pressure too. Is the cold pressure bad all over or just one or two fixtures? Pressure and volume often confuse home owners. When you first open a cold faucet is there a normal flow for a second or two and then it drops down? Please answer Mark's question

Answer Marks question. You hot water should be piped with CPVC.
Bob's on to something here. You have cold water pressure entering the trailer at the hot water supply. Follow the cold line from where you had pressure. Somewhere, along the line you'll find a blochage or an wrong connection. Good luck, Tom
