MIKE IN lINO III Posted June 8, 2009 Share Posted June 8, 2009 I need to replumb my Mobile home at the lake. I want to take out ALL of the copper and pex fixes and replace with all pex. I have a 3/4" feed line and then it goes to 1/2". At the faucets it's even smaller. I know the down sizing is for pressure build up...... wait for it..... wait...... Can I just put 1/2" throughout the whole trailer?Thanks, Mike Quote Link to comment Share on other sites More sharing options...
bbqhead Posted June 8, 2009 Share Posted June 8, 2009 Yep, Most of the trailers and park models I have worked on are 1/2inch throughout.randyRV tech Quote Link to comment Share on other sites More sharing options...
crothmeier Posted June 9, 2009 Share Posted June 9, 2009 IF you ahve a mobile home, not a RV or Park Model, i believe code says you have to run at least 3/4" if there are 3 or more fixtures(faucets,toliets,tub,ect) being run off that line? im not 100% positive but thats why it branches down, so you have enough volume first off, then pressure. if you are using more than 1 fixture at a time with only 1/2" you might have volume issues.

MIKE IN lINO III Posted June 22, 2009 Author Share Posted June 22, 2009 Any idea what pressure I should be running the water at?I am doing a temporary fix until I have time to replace ALL of the piping. It seems that when I fix one split and pressure up the water I get more. Currently running at 35 psi.Thx, Mike Quote Link to comment Share on other sites More sharing options...
