Bounder: Water pressure very weak

[airborne5]

Hey sorry for 2nd post but I have replaced almost all of my CPVC with Pex tubing. Even before I had the water leak that caused me to replace almost all of my plumbing, I never had good water pressure. I have turned on the water pump but that didn't change anything. Unless I am doing something wrong every valve I open doesn't improve the water pressure. The only thing that I noticed is if I open one valve it pumps water into the freshwater tank. After replacing all the water lines I only have 1 water pump and 3 valves to switch. 1 sends water to the freshwater tank, 1 is the water heater bypass, and one is on the water pump. What am I missing?

Forgot to add that is is a 1998 Fleetwood Bounder 34J

A bad bypass valve can cause low water pressure. If you can connect directly to the pluming bypassing the valve you could see if your water pressure increases. If it does then you would know.

Some water heater bypass valves have an adjustment on them also. This adjusts the pressure also. Without a plumbing diagram I can't say for sure on your rig.
