NEW Quality REPLACEMENT THETFORD O'RING SEALS x 2
If your toilet locker is leaking, in most cases it is the door press button lock seals, if not regularly lubricated, they split and let water in.
These replacement seals fit securely around the button and give a tight water seal, if you remove the inner cover and find the recess marked with dirt and silt, this is a sure sign that the button is leaking.
We have taken some pictures to show the lock unit in place, just to help you re-assemble it after fitting the rubber.
