Thetford Toilet manual pump replacement corcetina type bellows

[Pauldrummerdad]

Our Theford toilet manual pump (twist the handle type) in our 10 year old fleetwood has lost it's springyness and slowly inflates drawing in the water. I think the severe cold did it in, although it had been drained down. Has anyone replaced the corcetina bellows on this style of thetford toilet unit.

Thank you

Excellent advice. Found the PDF file. Dismantled the pump and found the one way valve in the intake pipe gummed up. Cleaned it and now the water cascades out like a whirlpool.

Thanks for your help Sproket.
