Some Background:
So... a little while back I replaced the electric water heater. We get a lot of minerals and sulfur gas in our well and it was finally too much for the bottom element. It was a straight-forward job of unscrewing the hot and cold lines from the insulated nipples, slide the old one out, new nipples, crank down the flex lines and reattach the 220. Only real difference this one has is the digital temp deal on the side... set at 130F. I know some won't like that temperature but there are no children or elderly but I have immune issues left over from Lyme disease and it's not worth not having your water at biologically safe temperatures, especially with a well.
The Problem:
Ever since the installation I have had air in the hot lines. This is present in both the feeds to the front and back of the house and affects all the spigots. It never gets worse but it never gets better... any time you run a faucet it is fine until the hot water makes it to the tap and then it gurgles and spits every few minutes.
I can't see any way for air to get in the lines at the heater level (they split right above the unit) but that's where it has to come from or it would not affect both ends of the house. I wondered if the holding tank was water logging any faster than usual, but it is not (old fashioned but not old galvanized tank style). We get the sulfur gas like many wells out here that turns everything red and brown but one would not think this would occur from that on the exact day the new heater is installed. It certainly is annoying.
What could be causing this?
Thanks.
