I have a shurflo 2088-404-144 water pump that the motor runs, but it isn’t pumping water. Anyone familiar with this unit? And what can I do besides replacing the pump?
I would check the voltage at the pump, make sure water is getting into it and if all that checks okay (and most likely is) replace the pump with a HydroMax pump part # P25201. It should be somewhat of a direct replacement but with 15 more psi. I think the shurflo 2088-404-144 is no longer available.And what can I do besides replacing the pump?
I replaced mine with a higher pressure unit but I know my plumbing is rated for it. Older RVs May only be rated for 40psi.I would check the voltage at the pump, make sure water is getting into it and if all that checks okay (and most likely is) replace the pump with a HydroMax pump part # P25201.

But you can buy the exact same Shurflo 2088-404-144 unit as used here.

60 psi is the least rating I've ever seen, and that was back in the 80's. It's pretty much standard that RV water pumps come factory set at 40-45 psi, putting them well within the max pressure envelope. RVIA standards have called for pressure tests around 85 psi since the early 2000's.Older RVs May only be rated for 40psi.
