As has been stated you may have a gas in your water. Check the faucet with a match.
Are you talking about natural gas? That doesn’t seem like a harmless thing to have in drinking water.Have the same problem. Turns out we have gas in the water. Most noticeable in the hot water because it is contained and the gas is able to dissipate but is captured in the water heater then pushed unto the waterlines. Harmless but a PITA. Well is 25 years old problem popped up in just the last 2 or 3 years.
Well worded and probably correct. In the Northeast, we've been captive air tanks for a long time, but when I was a kid, we still had galvanized tanks and air releases.Your tank is air logged. Since you have a hydro-pneumatic tank (air over water), you have to keep an air space up in the tank. For your system, it is accomplished by using a bleeder system.
A bleeder system usually has 4 parts. The bleeder in the well, which is usually just a rubber flapper that closes when pressure is applied, and relaxes when the pump shuts off. It opens when the pump is off and drains the water, usually placed at the first coupling 20 ft down into the well. It can also be a brass bleeder with a ball check, or simply a drilled hole that always leaks a little.
There is a check valve between the well and the tank, and then a snifter valve to let air in. And finally an air control on the tank (air release).
When the pump is running the bleeder is held shut by pressure. When the pump shuts off, the bleeder relaxes and the water can drain out. The check valve keeps the water in the tank from back-feeding into the well, and the snifter valve releases the vacuum and lets air into the line as it's draining. The snifter valve can be on the check valve body, which is called a "tapped" check valve. When the pump next starts this section of piping is filled with air. The air gets forced to the tank, where it goes to the top to keep the air head maintained. The air release on the side of the tank has a little float, when too much air gets into the tank the float drops and lets the excess air out.
Sounds like your air release (avc) is not working right.
Very common system here (SE Texas).
You might actually have been generating hydrogen from the anode. When was the last time that you pulled your anode to check if it was clean and still had material on it?Do you have a electric water heater. I replaced my electric water heater that was leaking with a Richmond unit from Menards. For about 6 or 8 months had lots and lots of air in the system. But only in the hot water. I even called Richmond. I was sure that the heating element was causing it to cavate and produce air. You could even hear it when the system would be heating. Richmond blew me off and said it was my hard water!! I have a water softener too.
But the one thing the Richmond rep. told me is that they started using stainless heating elements. So people would not burn them out on a "dry fire" I really think it took a while for the element to build up a little calcium and not work as efficiently. and then the noise and air went away but not until about 6-8 months later.
