How to Increase the Water Flow in Your RV
My family complains about the water pressure for some reason. I have no problem with it, though; I can't fit in the shower. I am way too tall. Is there any way I can increase the water pressure for the sinks and shower?
ANSWER: Hi Scott, as far as your RV water pressure is concerned, most RV manufacturers recommend that you do not exceed 40 to 50 psi of water pressure in an RV to prevent burst pipes and damage to your RV. The problem in your RV may not be a pressure problem as much as it may be a flow problem. There are ways to increase the flow of water without increasing the actual pressure.
The first place to look is at the water fixtures of the RV. Unscrew the showerhead of your RV and look for a water flow restrictor and remove it if you find one. These flow restrictors can also be in the screw-on faucet aerators on the kitchen and bathroom sinks. If you remove the flow restrictors, that will increase the flow of water to those fixtures.

If that still does not get you enough flow, you might want to check on the type of RV Water Filter
you are using on your RV. The rule of thumb for flow through an RV water filter is the smaller the filtering surface, the less flow you will get; the larger the filtering surface, the more flow you will get. So larger water filters usually provide more flow.
RV Water Pressure Regulator
You may also want to replace your current RV Water Pressure Regulator
with one that provides more flow or is adjustable (like the one pictured above).
