Water pump recommendations..

Hello all,
My water pump now needs a tap tap to get it started.
Several times a day.
Actually, like once an hour. Lol.

Anybody have information on good and bad brands?

This unit is a Pentair 4008 Revolution and has lasted about 2 years with liveaboard duty cycles.

Thanks,
gh
  • Electric steps will act the same way when the brushes are worn. Tapping on the motor forces them to make contact again - for a little while. You need a new pump.

    I bought a variable speed Jabsco (FlowJet) water pump and then installed an expansion tank with it. I can't hear it start or stop unless it's very quite in the motorhome (TV muted). I love not hearing "burt-burt-burt" all the time as I'm drawing water with the pump kicking on and off.

  • Im taping at the pump end.
    I might be able to tap it towards the back too.
    It doesnt take much of a smack to get it started.
  • I too don't understand what it is you need to "tap" to get the pump running. My pump is in a "wet compartment" where I'd have to go outside and open the door to get at my pump.

    I can turn my pump on or off at 3 different locations (the kitchen sink, the bathroom sink or inside the wet compartment). All three switches go through a multi-switch box that permits this to work.

    Are you tapping on a relay or on the pump itself?

    OK. So you turn on a faucet, and nothing happens? Then you smack/tap the water pump and it starts pumping?
    Never heard that one before. Weird.
    Usually, it's the other way around. No taps/faucets open, and pump won't stop running.
    At least you know your plumbing is tight.:B

    Thinking about this comment, what do you mean once an hour?
    They aren't supposed to run continuously, unless you're leaking air/water. They only run when there's a demand for pressure.
    What are you doing that requires it to run once an hour?
  • In our last 2 mh's I've added a 1 or 2 gal bladder pressure tank. It eliminates short cycles, and you can flush the toilet a few times at night without the pump coming on. I know you young campers don't need to get up at night.
    With the bladder it does not matter what position the tank is mounted in.

  • ShurFlo anything. They're bullet proof.
    Why not replace it with the same pump?

    Ever clean the screen/trap or determine why the pump needs help?
    Might be something simple like wiring.
