Is there any kind of quick-fix for a leak in a suction-side line? I'm assuming not, but hoping there's something like what my mechanic used to fix a seal in some head gaskets of an old car. I'll have to do some more investigation, but I'm about 80% sure there's a small leak in my skimmer's return line. This isn't as dire as it initially sounds because I can block the skimmer line, and have installed a new skimmer on the vacuum line, but it's still something I'd like to take care of. Unfortunately, virtually all of my skimmer line runs under either my pool or concrete patio, so accessing the pipes will likely be an expensive nightmare.
