Macerator toilet problem

[fudd]

Good afternoon. I have a Matromarine toilet that won’t flush. I’ve rodded all of the pipe work, still no joy. I’ve run it without the check valve, no difference. I’ve run it with the discharge pipe directly into a bowl and it works fine. Any advice will be helpful. Thank you.

If it discharges into a bucket, the pipe is blocked somewhere you have yet to find.

You can’t be wrong. I can only think that there could be an airlock somewhere.

and your sure the tank is empty/not full and the tank breather is not blocked/clogged.    might be worth opening the pumpout fitting and trying it.  and/or flush whilst pumping out to shift any blockage/airlock (if your lucky)
