choosing fitting for repair

[rbs]

Discovered a water leak above hot water heater at a T connection. Very limited space is going to require a use of a Shark Bite style connector, which Home Depot shows they carry. Don't see any other method of making the repair, don't have room for a crimping tool. Looks like I'm off to Home Depot, need to get my water going again. If any suggestions or advice on the repair/choice let me know, kinda stuck for options

I haven't used the Shark Bite fittings on my AS yet, but they work well on the pex tubing on my house. That's what I would use.

If you use the Shark Bite fittings you'll have to make sure you clean all the crud off those pipes, and also make sure that there are no defects/deep scratches/etc or you may not get a good seal. Those fittings rely on an O-ring to make the seal, and if that O-ring hits a damaged part of the pipe it will leak.

Possibly it would be worth a try with a brass barbed fitting and some good quality hose clamps.
