The Dump Mate has been specifically designed to fit the standard NZMCA dump stations. It fits in the Thetford sewer pipe, where you simply screw the cap off and place your Dump Mate in the pipe.
To fit larger sewer pipes you will need an adapter.
We had thought about getting a mould made to make these adapters and sell, however, we came to the conclusion that we probably wouldn't sell enough of them to cover the cost of the mould.
Here are the instructions of how John made an adaptor, to fit a larger sewer pipe:
From Bunnings he purchased a 100mm Optim DWV Screw Cap, SCU number 0191690, cost $14.45.
Then drill a 76mm hole in the centre, using a hole saw.
Then glue onto the inside of this, a 60mm length of 80mm drainage pipe, John used Marley Gold Plumbers Glue to do this.
Hopefully the photos will help explain, but if you are stuck, give John a call, on 021 979323
You might even come up with a better idea and if you do, please let us know!
