T&T: Holding Tank

[Mel Kowal]

I second the swap from Jabsco macerator to Sealand diaphragm. Got tired of 
changing macerators. The Sealand has been trouble free for years as long as 
the discharge valve is kept open. I installed a current activated switch in 
line with the pump so that when the holding tank is empty the switch senses 
the decrease in current draw and shuts the pump off. The pump is reset is 
by turning off the pump circuit breaker. Works great. Switch details are on 
the boat, far away.
