In response to Re: Well Pump on/off, on/off, on/off
: We are on a well system for our house H2O. Recently the people who installed our softener/filtration system added an oxygenator to the input side of our pressure tank & switch to eliminate a "sulfur" smell in the hot water. Now the pump is going on & off every time we run the slightest amount of water. Is it possible too much air is collecting in the holding tank? Is the pressure switch going bad? I don't know if it's coincidence or a result of the oxygenator. Please help if you can. Thanks for the great web site.

What you have is called an air injection system; they use a venturi that sucks air into the water as it passes through it. It won't cause the 'short' cycling that you are experiencing. It can cause a lag in the pressure switch and gauge seeing the pressure though. That would cause a hesitation in the pump coming on and shutting off. The cause would be dirt' or rust etc. blocking them and/or any nipple or tubing connecting them to the plumbing.

If you have a captive air type pressure tank, the bladder may be broken. Check the air pressure in the tank with no water in it. It has to be 2 psi less than the cut-in pressure switch setting. I.E. 28 psi for 30/50 psi water pressure. If you get water when you check the air pressure, you know the bladder is broken. Same if you get water vapor as you vent some air out of the tank. You can do that with water in the tank, but only a spritz or two of air. Hold your hand so the air forces any water or vapor onto it.
