Dear RV Doctor, we cannot get the water to come to the sink in our camper with the equipped hand pump. It was working fine not that long ago. What could be the problem? We keep trying and trying but the hand pump will not bring water to the sink. And yes the water tank is full.

Answer:
Kris, it’s quite likely there is an air leak somewhere in the hand pump itself or in the hose between it and the tank. Check the hose carefully for any splits or holes. Some simple hand pumps were not usually constructed under the strictest of tolerances and it may simply be faulty. Though replacement hand pumps are readily available at any Camping World store, it may be time to upgrade to an automatic 12-volt demand pump, even for a single sink configuration in a truck camper. It would depend on how much time you actually spend in the RV and if you have the space to install it.
