I would never want an underwater bilge pump discharge. I know this from waking up to knee-deep water in Rock Hall one night. Just Say No and run it out a normal above-the-waterline fitting!

This is from a UK supply but you get the idea. http://www.force4.co.uk/4585/Force-4-Cockpit-Non-Return-Drain.html Two details of importance: - the bilge pump goes to the large port of the Groco manifold as the (large) primary user, the heads basin then has to go to a smaller port and should have a screen at the basin to minimize fouling at the manifold (shavings & other hair are very real plugging concerns with an elbow transition to outlet. - the bilge pump will REQUIRE a vented discharge loop to prevent siphon when idle and the internal check valve leaks-by. Another idea: My toilet intake passes under the heads basin. So I teed the basin drain into the toilet raw water supply. It works like a charm, basin drains out the intake trough-hull and when the toilet gets used there is good agitation to clear the basin drain. As an added bonus, being a salt water high organics boat area, before I leave the boat for any length of time I close toilet supply through-hull, half fill the basin with fresh water and pump through the toilet. When I get back and use the boat there is no sulphur smell in initial uses of toilet, sweet :) Cheers, Russ Sweet 35 mk-1
