The Explore hand pump fitted in our van requires a number of initial pumps to prime it before any water comes out. Should it have an anti-drain back or one-way valve fitted to prevent this? Or is this a sign of a worn out hand pump not sealing? Both of above, they are a mongrel pump at best. I made a coil of pipe under the sink, this helps prevent backflow, fitted a one way valve as well.
