Hi Peggy,I have two manual heads on a 1981 Morgan OI 41. Each has a rubber bladder type holding tank with a series of old frozen valves and pipes. They are the same. Each has the usual small intake hose and large discharge hose. There is a diaphragm (sp?) pump set up so it will empty the holding tank back through the same through hull that the head would pump out through if the valves are properly aligned.I want to install a Y valve for holding tank or through hull, and either use the diaphagm pump or add a macerator pump to empty the tank. We have a holding tank law coming into effect in here in BC in January, but very few pumpouts. Do I need a seperate through hull to empty the holding tank via a macerator or diaphragm pump?Do you have a diagram that shows a system like this?Any advice on how to do this? Are Y valves the way to go?Is a small diaphragm pump a resonable way to pump out a (maybe 15 gallon) holding tank? Many ThanksFred
