If I up grade to a new 3 gpm pump vs 2.5 gpm water pump the new pump shuts off at 55 psi vs 45, will my water lines hold up ? I also just installed a new domestic 320 toilet.
I have found in the various RV's I've owned that the fixtures are usually the weakest link. Most notably the shower valve. I am still searching for a decent one not made of plastic painted to look like metal. Maybe I am unlucky but it seems like every shower valve in every RV I've owned has leaked if the PSI gets above 50. Would love to find a decent one.
