Water pressure

For about as long as I remember we've been told to set pressure regulators at 40 psi. If I wanted a good shower I turned on the pump because inlet water was not enough.
Well,we had to change out the water pump. It's an Aqua flow with 5.3 gallons per minute at 65psi, at ten amps.
It can be set to 75 lb according to the website unless it is referring to the 115 volt version.
Motor is good just need to rebuild the pump section.
Haven't heard from the factory if they sell rebuild kits.
Put in a box and in the bay for a spare.
It has lasted 12 years, with a lot more use than the 3900 miles on the odometer.
  • Just dealt with low pressure @ my shower head.
    Problem was caused by blocked passages at restrictor plate at shower head.
    Drilled mine out and increased the size to 1/8"
    Removal of restrictor plate as mentioned above would work just as well.
  • I'm @50 as well, and he's running 50% above us, bumping up on what's considered "high pressure" around 80
  • PEX is rated at 100#

    55# for an RV is not an issue

    I set my water regulator at 50# Static

    For better flow at shower..........remove/enlarge restrictor in shower hose.
    Some are removable. If not just enlarge with a drill bit

    MUCH better flow thru shower head.


    Turning water pump on doesn't increase flow or pressure unless pump flow/psi is higher than connected water supply source.
    Pump will not run if lower........city water check valve will close if higher
  • 40lb is to keep from blowing out the plumbing out. If you're looking for a better shower, change out the head before you get to fix a joint in the middle of the wall. It sux..
