I also have a hand pump faucet in my Scamp
. I first removed the old water line and replaced it with new. The old one was was absolutely gross! I also half-filled the water tank with water and vinegar, then left it in there for a few days, did a little driving around to slosh the inside of the tank. Then I emptied it and half-filled it with water, drove around and sloshed, emptied and half filled it again.
In the meantime, I removed the hand pump, cleaned it thoroughly in a water/vinegar solution. There's a little marble inside it that (kinda sorta) prevents backflow. I tested the faucet by putting the intake end directly into water and pumping the little handle. Took a bit of pumping, but it produced a good flow of water. I was wondering, as I reinstalled it, just how long it would take for that little handle to get water all the way from the tank to the faucet. I started pumping and pumping and pumping. Ran out of patience and...don't be grossed out
...I figured I better give it a little help. I sucked on the end of the faucet while pumping the handle until I heard water sloshing around the little marble, then quit the mouth-to-faucet resuscitation. A few more pumps of the handle and success! Out came the water! Picture doesn't show full flow.
It does lose pressure pretty quickly when not used right away, but it does work. Anyone have ideas for what to use to create suction other than my mouth?
I've noticed a little leaking around the base near the handle, so maybe there's an o-ring or gasket that needs to be replaced. Does anyone have advice of the best way to revive the hand pumps. $119 just isn't in my budget at this time.
