Water pump won't shut off
My snow birding neighbor has a 2015 Dutchman Razorback that has a Artis water pump. It runs fine but it won't stop running unless it's turned off. Any thoughts? Thanks Ray

I've run in to a couple of new Shurflo bypass pumps where the bypass pressure was set higher than the cut-off pressure.

Disregard if it's a different pump. :)
From the Shurflo manual
NOTE: By-pass adjustment should only
be performed by a professional technician with proper gauges and equipment.
The by-pass is a spring loaded diaphragm that opens up allowing water
from the discharge side back to the inlet side. The by-pass is set to begin opening
at about 40 psi and creating full by-pass at about 62 psi (lower pressure pumps
will vary depending on the by-pass and pressure shut-off settings). The pressure
switch on the pump is set to shut off at 55 psi. If the switch or by-pass
are adjusted too much, the by-pass and switch shut-off can overlap and
THE PUMP WILL NOT SHUT OFF.
Screwing the switch screw in clockwise will raise the shut-off pressure.
Unscrewing the switch screw counterclockwise will lower the pump shut-off pressure.
Screwing the by-pass screw in will raise the pressure at which the by-pass starts
and raise the full by-pass pressure.
Unscrewing the by-pass screw counterclockwise will lower the pressure at
which by-pass starts and lower the full by-pass pressure.
WARNING: If full by-pass is reached
before the shut-off setting, the pump
will not shut off. Full by-pass pressure
setting should be at least 10 psi higher
than pump shut off pressure.
Disregard if it's a different pump. :)
