I still have a few questions relating to my salt water deck
1. I've bought a new 6.0 gpm deckwash system. The "installation manual" says the pump "is self priming" and can be located "2 or 3 feet" from the water
source. Is that the maximum distance or is that the maximum vertical lift
, or does it make any difference whether it's horizontal or vertical? What about height above water
line? If its mounted below waterline, won't the line be primed anyways? If its mounted 3" above the waterline, but 10 feet from the thruhull, will the pump only have to lift
the water 3", so it won't matter how far it is from the thru-hull?
2. The pump has some sort of proprietary snap fitting for the inlet and outlet hoses. Are these safe enought for mounting below the waterline or is that too risky?
3. If I want to be able to remove the hose from the deck
fitting when not in use, do I need to have a check valve, or shut off valve, at the deck fitting, or in the hose, or not at all? The Jabsco
deck fitting looks like its just an open valve and the check valve is in the hose fitting, not the deck fitting. If there isn't one in the deck fitting, won't the pressure switch on the pump think I've pulled the trigger on the hose gun whenever I unhook the hose?
