Water pump

Now that the van is inside, I notice that the water pump needs to be primed after about 1-2 weeks of non-use. A nice winter project - find the make, serial or model # and replace it. Unless it can be rebuilt?
 
Have you tried cleaning the filter on the fresh water in side of the pump?
Drain your water system, disconnect the input water line from the tanks/system to the pump.
If it's a Shurflo, the filter is probably in a hockey puck shaped assembly at right angles to the
main motor housing. It comes apart by press and twist, like a child proof pill bottle.
Mine was really gunked up and took a while to prime. A service guy showed me how to take
it apart and rinse the plastic filter. My pump now takes about 30 seconds to prime after a
period of inactivity. Also, these things are designed to run dry for quite a while. During priming,
for example.
Save your money, it might just be plugged up.
 
Thanks for the 2 replies guys. Probably posted between CFL games? I did prime the pump using a suction hose on the sink faucet, that was pretty easy. After that, I turn on the pump weekly. It only runs for a second or so and all is well. I will have a peek at the filter. However, I thought ideally, during a period of inactivity, the water should not drain back into the supply tank. Which makes me think a faulty seal is the issue, rather than the filter. In any case, everything is 22 years old and age does have an impact.
 
Did we sound like we'd been drinking? :partyman:
You said "ideally, during a period of inactivity, the water should not drain back into the supply tank.

I agree. I've also found few, if any, RV systems function as well as their household counterparts.
In my experience, so far. YMMV? :wink:
I would try cleaning the filter/screen to see of it improves the "prime time", but I understand that
logically it shouldn't. However, while you're fiddling with it, you could check/tighten the connections
to the pump. Might make a difference?
I have to clean mine now that I've drained for the winter. It only takes a few simple tools and a few
minutes to complete. It saved me a few bucks, as I was ready to replace mine, too.

Good luck with it, no matter what. :thumbup:
