I am losing my mind with a
bilge pump project-maybe you all can save my sanity. I have a DEEP bilge-like 48" deep. I have a great high capacity
water pump that is alarmed and wired to a counter-works fine. I am trying to install a nuisance
water pump to remove rain
water that enters the
bilge via the stowaway
mast. Rain runs right down the large
mast slot and drains into the
bilge. I installed a mast boot, minimally effective and there is always the drip from the stuffing box. Eventually I will buy or make a "dry bilge" diapragm
pump and tubing solution to get the last drops, but first I have to get the lower capacity nuisance
pump to shut off aft?er it is activated by the
water witch
sensor.
The nuisance pump has a check valve installed right after the pump to prevent water in the long hose line from draining back after the pump shuts down-seems to
work well (kind of clunky-bought from a
plumbing supply store but has low resistance which I would think is a prerequisite) BUT the water that remains is enough to trigger resistance on the nuisance pump impeller such that the pump thinks there is enough water to require pumping. I'm talking like a 1/2" of water. Result is the pump cycles on and off continuouisly and would drain the
batteries eventually if left it unattended. The pump is a Johnson 1000 GPG pump-had the same problem with a
Rule 500 GPH pump. Anybody got a model recommendation that would solve this problem?
