Well Water has Air Bubbles


My wife and I recently purchased our first house. The house is currently hooked up to City water, but after going in the crawl space we noticed that the house also came with a well. The well had been disconnected so we decided to hook it back up to use for irrigation. After making sure everything was connected we attached a garden hose to it and ran the water. From there we noticed a couple of things, the first being air bubbles in the water flow. Second is fluctuation in the flow of water. Can anyone suggest anything to resolve this issue.

Is it a submersible or jet pump ? Is there a pressure tank ? Pressure switch ? More info.

You should pull a water sample and have it tested too just to be safe - even if it's only for irrigation. No telling what could happen in the years the well wasn't in use.

Thanks for the replies. It is a Jet well and has an expansion tank and pressure switch. It took about 3 minutes to fill up a 10 bucket.

Well Water has Air Bubbles


The air bubbles may possibly be from a leaking bladder in the pressure tank, or there could be a fitting leak on the suction (well) side of the pump sucking in air. Most likely it's a bad tank bladder.
Turn the pump off or unplug it, and drain the water pressure down until it stops running out.
Now, check the pressure in the tank with a tire pressure gauge. It should read (and hold) two psi below the pump cut-on pressure (i.e. 20 psi cut-on to 40 psi cut-off should have a tank pressure of 18 psi when the pump isn't on and the water pressure is drained down).
If the pump is set at 40 psi cut-on/60 cut-off, the tank pressure should be 38 psi. If the tank pressure is too high, bleed the air pressure off to the 2 psi below. If it is too low, air the tank back up with a portable compressor or air tank.
If water spews out of the pressure tank air valve, the bladder is shot and you need to replace the pressure tank, which is what I suspect will solve your problem.
If you need to know how to prime the pump later, just ask.
Good Luck!
Mike
