Is this the Shurflow pump style that most stick on top of a 5 gallon jug of
water? If so then the pump is self priming. If it no longer primes then one
or both valves inside the pump are going bad and its time for a replacement.

Subject: shurflo faucet pump priming problem
I love the shurflo faucet I installed in my Westy sink, but I'm starting to
have some problems getting it primed. This shows up when I first fill the
tank with water, and the problem seems to be getting worse. I'm also
getting an occasional squeal from the pump, so I suppose it will die soon.
I got that replacement pump, mm, maybe 8 years ago. Is that about right for
pump life span?
Back to the priming... Theoretically, I can see where this faucet would
cause a problem because it has a valve in it, and the original one does not,
iirc. So with the original there would be nothing to keep water from going
into the pump as the tank is filled. But the shurflo's valve being closed
would sort of airlock the line all the way down into the pump preventing
water from entering. Then you turn it on which opens the valve, but the
pump is already spinning full of air. Non-theoretical, why did it work when
I first installed it and for several trips after that? I like the valve in
the shurflo because I can conserve water, using only a trickle when that's
all I need. But the pump is going full speed and working against that
mostly closed valve. Maybe the shurflo damaged my pump? I doubt this, and
can't remember reading anything to that effect.
I was going to wait a few hours and make this a Friday post "subject:
do you suck your shurflo?" Yes, when my faucet doesn't work, I suck it. I
turn it on and suck it a little and then I hear the pump slow down and it
starts pumping fine. On my latest trip, the worsening symptom was that this
occurred a couple times as the tank got low. I was on mountain roads so
there was a lot of sharp curves, which could have sloshed all the water away
from the pump.
Let me hear your experiences and ideas please.
