Bissell Proheat 7901 has continual leakage from

\015 Bissell Proheat 7901 carpet shampooer has continual leakage from the spray heads after the trigger has been released. In disassembling the machine, the tubes to (before) the switch (in the handle) are charged, but all tubing between the switch and the spray heads is empty. Is there something about the switch that would be allowing air into the line? Or the tubing at the switch? Or. . . ?\015 – Bissell 7901-1 ProHeat Scotchgard Upright Wet/Dry Vacuum

Hoses to and from pump

\015 When I removed the pump to this unit to go buy a replacement I wrote discriptions of where the disconnected hoses went. Apparently my descriptions were poor. Now after switching the hoses all around I am not sure where they go. How can I find out where they are supposed to be connected?\015 – Bissell 7901-1 ProHeat Scotchgard Upright Wet/Dry Vacuum
