Hi,
I have a 3/4" loop sticking out of my drywall in the garage next to the water heater. A neighbor that has lived in the devolpment since they were new tells me that it is a loop to install a recirculation pump.
I originally thought this was for a water softner, but a few years back I installed a softner and used this loop....oops, uh nope. I wish I could remember the details, I think when I had the feed shut off to the softner I was still able to get water out of faucets. That was when I asked the neighbor and he said it was a recirculation loop.
This is a southern California house built in 1980
Is there any way I can confirm (without pulling down drywall) this is loop for a pump?
If it is a loop do I need a check valve?
Is there a standard for flow direction when these where installed, if not am i assuming correctly that once the system is drained and the loop opened that I can open the main valve a bit, fill my system, and figure out flow direction?
thanks in advance
Tom
