Hola,
It is the lowest point, in this case the outlet, of my newly designed gravity drain system. No pumps, Y valves, macerators, etc. My
head will discharge into the top of the tank, which I have mounted approx. 2 above the waterline. We are a sailing
catamaran so angle of heel is of little to no concern in my case, I have all of my fittings-vents, pump-out, 4 clean out access port, and inlet from
head on the top and of the usual 1.5 variety, except the aforementioned 4 access. However to reduce the chances of clogging, the gravity drain fitting is a two inch exterior slip fitting(nipple)which I had attached via spin welding so that 2 ID hose can be double clamped to it and then attached directly to my below waterline thru-hull for discharge. This will minimize my hose connections below the
tanks potential
storage level.
I have found a supplier of butyl hose from the Uk in 50mm, which will
work in my application if need be. Just curious if anyone knows of any other options.
