About a year and a half ago, a plumber replaced a 3 foot section of copper pipe that had developed a pinhole leak. He put in a replacement section using sharkbite fittings because both ends of the section were cramped and close to wood.
Copper pipe, cold water line to our hot water heater, I don't know what "normal" pipe size is, 3/8" I guess? Our water here (Vancouver BC) is really soft.
Today I noticed that one of the sharkbite fittings had a slow drip coming from it. It just started because it's in a location that I look at pretty much every day (corner of the basement where I park my bike). When I got up and looked at the fitting, I can see the water seeping and dripping, it's maybe one drop per minute.
I haven't looked up yet whether it might be leaking because the pipe wasn't quite seated or has somehow worked out a bit. I'm going to try that and then get someone in to replace the fitting. In the meantime, I'm wondering if the fitting might blow apart. It's easy to catch the drip right now, but I wonder if the fact that it started leaking means it might fail completely?
I guess a related question would be: what would make a sharkbite fitting start to drip after a year and a half?
