Replace Henderson Mk5 with a Macerator?

[Captain Coyote]

Hello all-

I just rebuilt my Mk5 in the head and I can NOT keep it completely sealed. It worked flawlessly for two days then started leaking again. I'm really flummoxed. This system is so simple and I'd say I'm a solid 8.5 / 10 on marine mechanical prowess. Everything looks, sounds and works great when I have the pump out. But once I get everything back together, I'm getting leakage on the dry side of the diaphragm and it leaks out of the drain hole on the back. (I also installed new hoses, BTW.)

I'm wondering if there's a way to just replace the Mk5 with a macerator. Preferably right down at the discharge port on the head, but any whichaway that works is fine with me.

Has anyone tried this?

Thanks-

Chris

You are using a bilge pump to empty the head?  Whatever works, lol.  I imagine you probably have a pin hole in the diaphragm.

If you use a macerator pump at the discharge from the head you will need at least one joker valve between the head and the pump.  My electric marine elegance head had 2 joker valves in line. Though I haven't tried it, I can imagine the explosive fountain coming out of your head without one.  Otherwise I can't see how it wouldn't work just fine.
