Sink plumping leaks


New Member
When they made my unit, it seems they did not brace the the roof vent line which runs to the sink drain and then down to the holding tank. I have a number of leaks at the joints and wondered if there is a better way of fixing it than using tub silicone caulking. I can't get at it to replace the pipes because of limited space.

Any help :dead: :angry: :question:
