Quality water pump

[Frankandbeans]

It seems the Shurflo in my 2015 Work n Play isn't up to the task anymore. It's making more noise than usual, and water pressure is lacking. The shower is useless, as it just dribbles out, and even the faucet pressure is noticeably weak.

Replacing the pump will require a contortionist, so I only want to replace it once. I'm seeing a lot of recommendations for Shurflo, which from what I can tell is a popular RV water pump, but as you might imagine I am a bit hesitant to go with them again.

New pump fixed the problem. Purchased Shurflo's water pump quieting kit...best money ever spent. Ever. Ended up putting both 3 foot sections of hose on the output of the water pump, giving it 6 feet of flexible hose before going into the hard line. The reduction in noise is nothing short of incredible.

I need to do that too. I thought the variable speed pump would be quieter but it runs at 100% most of the time you open the faucet.

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.

I see on Amazon that the 4048 is almost $100 more than the 4008,is a gallon more per minute worth the cost? or is there more to it than meets the eye?

Just pump water by hand come on you can do it!!!

Some pumps have a pressure adjustment screw in the head of the pump, I don't know about your model.

Assuming that's clear, it has to be the pump. There's nothing else in the system. The pump and everything has already been pulled. Once I figure out the hose is clear, it's just a matter of replacing the pump.

Sounds like you are on the right track.

Dial down the pressure on your air hose to prevent rupturing a line of breaking conenction, etc.

Ok, did some more testing. The screen before the pump had a couple of small particles in it, but nothing I thought would restrict as much water flow as it has. Cleaned it out anyways, no change. After reading the replies on here and looking at my setup some more, I'm pretty sure I got it figured out. The 90 degree valve by the dump tank valves looks like it closes off the hose that connects to the bottom of the fresh water tank, so that you can bypass the fresh water tank when winterizing it. Makes sense.

I put a bucket of water in there and had the valve so it would suck water from the bucket instead of the tank. Same low pressure. So, to me, that's saying the line from there to the fresh water tank is not the problem (no debris in there). Screen cleaned but made no difference.

Hooked city water up again just for the heck of it, water pressure is great in everything (shower/toilet/sinks).

As always...input is always welcome!

Does your system have a screen before the pump? That is the one that would cause the problem.

[Frankandbeans]

Forgot to say, everything works great when hooked up to city water.

[Frankandbeans]

Water pressure from all points are weak at best, including the toilet. Makes it hard for me to believe it'd be debris causing low water pressure (what's the chance of debris getting in every single outlet)? I will have to try the winterizing tube trick. Don't know what's involved. To Google I go...

[Dick_B]

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

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.
