Yipes, $65usd for a frickin' plastic valve at Waste Marine? I think
the pipe on my handsome, gleaming hand pump toilet is 1 3/8" or 1
1/2".

1.5".

Can't you use something from the hardware store?

I wouldn't. And I wouldn't buy the cheapest one from WM (which, btw, has
become the most expensive retailer on the planet!) either. If you want a
y-valve that'll last more than a few years, buy a Whale.

I want to Y the
waste to the thru-hull or the waste tank. I guess you need one Y-valve
and one stop valve.

Nope..you don't need a stop valve, just a y-valve inline. All your
thru-hulls should have the best quality ball valve (NOT gate valves)
seacocks on 'em you can buy if you don't want to risk sinking your boat.

If the toilet is below the waterline, you'll need a vented loop (3/4")
in the head intake (NOT between the thru-hull and the pump, but between
the pump and bowl)...if the discharge thru-hull is below waterline
(which I hope it is!), you'll need one in the head discharge line too.

I don't recommend Terry's method to dump the tank either. That can
result in blown hose connections or an eruption in the toilet.
