Quality water pump

Did anyone already suggest checking the screens at the faucets for debris? How's the water pressure when flushing the toilet?

Replaced our Shurflo 2088 with the 4008. What a difference!! water pressure is good but the new pump is very, very quiet compared to the old one. DH plans on rebuilding the 2088 and keeping it as a spare.

The Shurflo 2088 was discontinued couple years ago.

Any 'rebuild' parts would be 'old stock' if you can find any.

The 4008 is a 3 gpm/55 psi replacement pump
The 4048 is a 4 gpm/55 psi replacement pump


AS suggested.....troubleshoot current pump before throwing money at fix with new pump.

Get the model number of your Shurflo, then get install/owners manual instructions on-line. Look at trouble shooting section to find out what problem is. Probably easy fix.

Does your water system work fine when you are hooked up to city water where the RV WATER PUMP is not required... The City Water determines the water pressure in this case...

If you are only having water pressure problems when using the fresh water tank being pumped out by the RV WATER PUMP. Several things can be involved here lowering your water pressure...

One quick test you can do is stick your winterizing tube down in a gallon bucket of water and operate the valves to winterizing. With the RV Pump ON you should see great water pressure coming into the sinks, shower heads, etc with the pump running...

Air leaks in the lines are one cause for low pressure...

Clean he debris out of pump, screen etc.
If replacing then move the pump so you can accomplish this task easily.
