I don't know why these things always come down to a pissing match.
I don't recall exactly who brought up an AVC, but you keep referring to an AVC in the system as an air release. Don has a 2-stage jet pump. He does not need an air release because he has no excess air. You don't put air releases on a well system unless it somehow makes air, like some wells near here that are naturally gassy.
I just love it when a DIY tries to tell me how a well system works. Let me rephrase my answer. It's not about the pressure of air in the tank, because pressure is always controlled by the pump. It doesn't matter if you put 20 psi in the tank or 60 psi or air in the tank. The pump controls the pressure, not the air. What one tries to do is achieve about a 50/50 mixture of water/air based on volume. The volume of air in the tank determines the drawdown.
Heck, I did one the other day and supercharged it to 2/3's air. Probably had close to a 15 gallon draw down on an 82 gallon tank. Also, here's a little trick. Most pressure switches are set either 30/50 or 40/60. Tweak the switch to 30/60 to get a little better drawdown.
I think I was the one that said that I did not have a AVC, Because they did not work for me, My pump or tank.
Sorry if I was the one that confused the unknowing.
You can get off your high horse cuz you are not the only one that knows how a well system works. Go back and reread post #7. Here, I'll make it easy for you.
There is no such thing as "pre-pressurizing a non-bladder tank, because there is no way to keep the air in it, and the "pressure" will ALWAYS be the same as the water pressure at that moment. The best you can do is turn the pump on, and then when the tank is full, let a faucet "drip" slowly so it does not drop the system pressure too quickly. Then inject air into the tank to force the water level down to the desired point, (it will have to be by "guess" unless you have a glass sight gauge to show the water level). Then close the faucet.
hj, if the air is humid enough, the sweat level on the tank should give clear indication of the water level if you wait for the tank side to warm up to its surroundings. One can always lick the side of the tank with a propane torch to hurry along the process. I can usually tell just by holding my hand against the side of the tank, where the level is at but then around here water from the ground is damn cold.
Do you have a pressure gauge on the tank? I put in a nipple and a Tee so that I can have both a gauge and a schrader valve to use with my compressor. Half a century ago, I used a bicycle pump to add air to the tank. The tank was tucked under the stair landing and there was no room to stand up so I had to work the bicycle pump sideways. Remember it like it was yesterday.
When the pump is off , I would think that it is reading the tank pressure.
I could add another meter, but would have to worry about it freezing.
I have a heat tape to keep the regulator and Pressure switch from freezing.
But that is quite true. The float release is designed for submersibles.Quote:
My understanding is there are two types of AVC. One style only lets air out and works in conjunction with a submersible and a bleeder/snifter. The other kind takes air in and works with a piston or jet pump...
