Question

Hi i have a problem with my thetford c-402c l holding tank, it is leaking from the circular vent at the back! I have stripped it all down and think it is something to do with the seal on the vent which is fitted inside, can this be replaced if so what is it called. I am unsure how you would get to it to fit a new part? Please advise regards Clare

Answer

Please refer to the attached instructions to allow you to replace the vent seal.
