Noticed that PVC line between grey tank and drain valve has hair line crack in it. Is the a way to fix it without having to replace the pipe? Maybe with JD Weld for PVC & Plastic?? Thank you
If its a short crack go to Lowes or Home Depot and get a rubber fernco coupling and cut out the bad piece of pipe. If its a longer crack get two rubber couplings and a piece of pipe. Now you'll have a flexible joint and will never crack again.
