Hi Fellas, Just wanted to first thank you all for all the help over the years. I sometimes forget to reply with my graditude. Anyway, I have a customer that is claiming that she is having an increase is air coming through the water lines (milky water, some initial spudering) weeks after I installed a GE electric water heater. This did not occur with her poorly functioning heater that I had replaced. She is generally a bit fussy but I like to keep em happy. I have to go back tomorrow morning and want to be thouroughly prepared. any ideas? thanks red

No plumber
but, possibility that the changeover could have loosened some scale or other crud. I'd pull the spout screens and clean them off.
After that or maybe even b/4, I'd have called my plumbing sub that did the work and ask him to have a look.
It's possible that some air got trapped in the system somewhere, and is slowly working it's way out. but two weeks seems like plenty of time for that.
It's vaguely possible that the water is highly reactive and is reacting with the anode in the new heater, producing hydrogen or some such. Of course, if that were the case there'd be other signs of highly reactive water, such as copper pipes rotting through in 5 years. But swapping out the magnesium anode for aluminum might solve the problem.
Air in lines
Is this happening with the hot water only? is this on a well or a city system?
True, well water will sometimes get air in it from various sources. In particular, if there is an old fashioned air volume control then the control could be stuck and letting too much air in. Or there could be a small air leak in the suction line of a shallow well pump.
