Hello, I've had a couple of plumbers out here, and they left in defeat, stumped as to what is going on:
Every morning after the sprinkler runs, we have no hot water in the house (no drips, no noise, just nothing coming out of faucet). Cold water is fine. After much research in the forums, I narrowed it down to an airlock being created in hot water line (or electric HW tank) after the sprinklers turn on or off. Reason being, after I open up all the hot water outlets in the house for a while (sometimes hours), the hot water will suddenly 'pop' out and start flowing again.
I've got a 6 zone system, but only use 4 zones. Automatic controller. Run them for only about 5 minutes now everyday around 3:30am, one zone per day (2 zones on 2 days a week). Yesterday I tried closing the sprinkler's shut off valve about 50% to reduce the pressure, but no noticeable change. There's no hot water coming out of sprinklers.
Any ideas what could be going on here? Thanks for your help!
