I'm getting around to fixing the head. I figure all the seals are shot and am not going to bother with trying to figure out what's wrong with the current head. I'd like to put a Raritan SuperFlush in, but don't know if the discharge will physically fit. The Jabsco is nestled quite nicely as it is. First off, if the 90 deg elbow on the Raritan discharge can't be flipped and pointed up, it's a no go. The discharge protrudes 2" further back, but is higher so I think would work. All other dimensions I believe would work, even with the large version. What do yall think?
