Need a new water pump for a 2013 Alpine 3535RE

Hello, I would like to know which Surflo water pump will be a direct replacement for the original. I have not checked it out yet as the trailer is 150 miles away, Thanks, Pat

Are you sure it's a ShurFlo pump? Many (maybe most) Keystone RV's have FloJet pumps as OEM. The "main difference" (other than preference) is that ShurFlo pumps use threaded inlet/outlet connections and FloJet uses "locking ring push in connectors"...

The two aren't compatible without changing the end connections on your pump inlet/outlet hoses.

Typically, the pump is rated at 2.9 - 3.5 GPM. Anywhere in that range will work for an RV. The issue is which fitting type is on YOUR trailer? Buying a pump with the same type fittings will make the changeout much easier.

I'd also recommend a strainer to add to the inlet from the water tank. There's always sand, silt and even sawdust/plastic drill shavings in the tank. If they get sucked up into the pump head, they can destroy a pump or cause water pressure/pump run issues. A FloJet strainer costs about $8 at Amazon and a ShurFlo strainer about $10. The strainers are designed to work with the pump fittings, so they, like the pumps, are not interchangeable from brand to brand.

Pat here's the problem, the person that bought the trailer that was on the assembly line in front of or behind your camper could have a different pump. The omly way to confirm what's in your trailer is to look at the pump in your trailer.
