Waste outlet on chausson flash 04

[Cazzaj]

On the waste outlet under the back number plate we have a tee shape handle to pull out and empty, ie over a grate on a campsite, is a connection pipe we can get to use with the waste master, its about 2inch/ 50mm diameter

Not familiar with that particular mh but the waste outlet on mine is the same size as standard drainpipe from b&q.

The waste pipe is made from 40mm solvent weld pipe and fittings. This is not domestic waste pipe but the same as used in garden ponds.

See the link below.

To connect to a waste master you will need to find a universal adaptor and some flexible pipe.
