We recently built around a 1000 sq ft addition onto our house. The existing home had one or two additions to it prior since the main part was built in like 1930 something the plumbing is the regular yellowish piping but everything we added we used the newer pex piping. In the new bathroom we have a stand up shower and a separate big soaking tub my problem is the flow volume for the tub seems really low like to the point that I gave up on the faucet and when my wife was ready to try out our new bathroom I pretty much filled it up with a bucket line made of me and my four kiddos haha...Any helpful advice or something to try to increase the flow is very much appreciated
You clearly have a problem. I am going to venture a guess that some debris got into the faucet on install. This can raise havoc with water delivery. Can you disconnect the supplies going to the tub faucet and check the pressure at that point?
