My solar panel has a drip at the manifold, where one small tube connects to the main pipe. The panels are made by Aquatherm and are a webbed assembly, i.e. the small tubes are all joined together by thin plastic.
I'm thinking the best solution is to remove the problem tube, then plug the hole left in the main pipe. But, I'm not sure how to plug the hole, which looks like ABS.
Any suggestions?
