Humph. That shouldn't happen. Sounds to me like the pump is not getting a prime because a check valve on the output side is held closed. You might take apart the check valve on the outlet side and clean it, or replace the spring with a lighter duty one. Running the pump dry for an extended period will wear out the impeller, BTW. Could be replacing the impeller will do the job, also, if it is a little worn. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
