Question

Air in hot water lines (well system)


I recently had some serious excavation work done in my back yard (new septic system installed) and I now find that I have a lot air in my hot water lines. When I first noticed the air in the lines (while the contruction crew was still driving heavy equipment all over my property) I suspected they might have cracked my well casing. I dont think thats the problem now as I only seem to have this problem when a hot water faucet is turned on, and as the construction crew pointed out there was sign of moisture leaking around the concrete cap to my well (I dont know if this is a valid test, this is my first home on a well/septic system). I get soo much air in the line at times that a glass of water will look almost like milk for 30 seconds or so until the bubbles disolve.
At one persons suggestion I have since drained the hot water (which I do every few months anyway) but I see no marked improvement.
The air/gas does not appear in the lines all the time, nor just when turning the water on. I can let the water run for several minutes before it starts to sputter and turn cloudy. It will clear up as quickly as it started, only to happen again a few minutes later.
I have tried letting the cold water run and I have not noticed any such problem.
Any help/suggestions would be greatly appreciated.

Thank you
John

If it was the well I would think both hot and cold would be effected.
Check the pressure in your pressure tank.
If the bladder blows it dumps water in the water lines.

Thanks for the suggestion. If it was a blown bladder wouldn't that also effect both hot and cold? And would that not also cause a decrease in my water pressure?

Actually a blown bladder in a water system pressure tank usually causes no problems other than the need to add more air to the pressure tank every month or maybe slightly more often.

The exception is if the bladder tore in a manner that a flap covers the hole at the bottom of the pressure tank where the tank is connected to the water pipe.
