RE: Holding tank and water tank=which side for pump out and fill???

I agree, will keep the sea cock closed, but at the present time believe there is a slight leak thru the sea cock. Need a new macerator pump anyhow to pump out at sea, if and when I have to,-would rather not but never know. Since I believe there is a slight leak thru the sea cock I will loop the discharge hose to the sea cock. The sea cock is in good shape, in fact looks newer than other stuff on the boat so not sure if leaking or not. When I replace the macerator will find out if sea cock leaking. Might put a "T" in the loop so I can use that as a connecting point to pump the tank to my portable RV holding tank on wheels. Presently using a new shurflo macerator to empty tank from waste pump out deck fitting, but it is all it can do to get sufficient vacuum to get liquid up to the pump for pump out. Line has a sagging loop so there is always a little liquid close by to start but still marginal. It is right at the 4 foot lift limit for the macerator specs.
