, same line as the macerator is tied in to, being a standpipe that does not reach into the tank but stops at the top of the tank so no waste can be sucked up.
After many hours of sleeplessness and trying to figure this out here's what i'm thinking of doing to solve the issue. If I can find a suitable pipe (ABS or SS) I can feed it through the input fitting on the top of the tank. I would leave it long enough that it is a few inches of the bottom of the tank. Then I would reattach the input line clamping the standpipe and the pipe so i have a tight seal.
The other option though not as clean and requiring much more plumbing
in cramped and inaccessible spaces is to connect the macerator to the pumpout line. (not the preferred option).
Looking for feedback as to anyone else having a similar issue and solutions or just a gut check if this sounds feasible.
Not sure why the plumping is tied together this way.
Is your head an electric/macerating type?
Not understanding why the Macerator pump is tied into the waste line of the toilet, if it's not an electric
Macerator are usually 1 1/2" input to the pump, and 1" output to the holding tank input line, which is not usually a stand pipe, but stops at the top of the tank.
Could you explain further so I'm not shooting in the dark?
How is the holding tank pumped out?
Macerator inline to tank discharge line, on to Y valve, then to OVB, Or deck
Or sucked out by Pumpout suction?
Or is the Macerator just to liquefy the toilet contents, and empties into holding tank inlet.
A lot of folks use a Macerator to empty the holding tank, but it's not a great design.
As the Macerator can break for a number of reasons, then you have what's left with no way to pumpout.
