Sewer coupling leak - how to repair

[dennysbabe]

In our 2008 Sightseer 34M We have a small leak at the couplings on both sides of the black and grey water sewer valves. Both leaks are minimal but need fixing. Has anyone replaced their couplings and is it difficult to do with the black and grey valves being close? Appreciate in advance any feedback you might have

I probably should've included that they are rubber couplings held with 3 clamps each.

On my 07 Meridian I have the large rubber connecting piece held with hose clamps. I fixed my leak by loosing the hose clamps, once that was done I pushed the solid piping further into the rubber coupling. I noticed that the solid piping had shifted leaving litter room for the clamp to work. Once I reset the solid pipe and tightened the hose clamp no more leak.

Good Luck

On my 2018 Forza I replaced the existing rubber coupling with a longer one from Lowes so that it overlapped the pipes more.

I replaced the rubber tank coupling’s on both the black and grey tanks on my View a year and half ago. The rubber had started degrading with age. Tightening the clamps didn’t not solve the issue. I first realized the problem in autumn and knew I would be draining the tanks shortly for winter layup. I replaced both couplings in the spring having left the gate valves open all winter after draining and flushing. WD40 made the removal and install much easier. Waiting till spring meant there was hardly any mess to clean up.
