Removal of main waste water pipe

[RobGriff]

Hi has anyone removed the main outlet pipe from the waste tank , seems that I have blockage somewhere, could be in the pipe or the tank thanks

Have you tried blowing up it?
Pushing a piece of cane or stiff pipe up it ?
Removing it could break the plastic pipe

Will try a small bore plunger to see if that will shift it. Thanks Stealaway will have a go tomorrow

Advice will depend on what type of tank and fitting? Picture will help us to help you.
On Mine I can reach inside the large bung at the bottom and unscrew the securing nut inside if i needed to.

Your going to use a plunger is it your sink that’s chocked.
If not as said above blow up outlet pipe from outside.

Shove a hose up the outlet. Safer than blowing up it. I’ve found in mine, and others the blank that was cut/drilled out and has been left inside the tank.

All of the above...plus you can buy drain unblocker at a camping shop.

Careful with a plunger, you could easily burst a push fit waste fitting somewhere between the sink and tank. Better to use hose from bottom, gently at first, or an air line if you have one.
