Simplest way to prime an inline pump?

    Me and my husband recently acquired our first van (a converted Iveco) and we are having trouble with our water system. The current set up is an inline booster pump (whale 991) and a tap with a microswitch. The problem we have is how to prime the booster pump without altering the system too much.

    Does anyone know of a tap with a pump primer and microswitch or does anyone have any other ideas?

    Many thanks,

    Not sure what your system is ;but the whale 991 isn't really up to it. You would be better off installing a self priming water pump, not difficult to fit.

    those are the normal types used in motorhomes

    Hi and welcome to the forum:thumb:
    The whale booter pump is exactly that, a booster for a manual or other electrical pump sounds like it not fitted in the right place
    if your trying to use it on its own it should be piped below the water tank so that it gravity feeds
    If it has been installed incorrectly you can
    1. move the pump close to the bottom of the tank, and use a bit of pipe to fiit where the pump was
    2. fit a submersable pump in the tank,or another booster near the bottom of the tank
    3. fit a manual pump befor the booster to prime it
    4, fit a one way valve between pump and tank to prevent drain back
    after fitting valve you may have to manually prime booster by blowing into (pressurising) water tank)
    5. or persevere with running the pump with both hot and cold taps open, if sucsessfull dont allow tank to fully empty or you will have to start again:cry::cry:
    hope that helps

    Agree with sinbad .. I would fit a Shurflo or similar

    as an added bonus, you won't need/use the micro switch in the taps, one less thing to give trouble..
