WELL WATER TANK AIR RELEASE VALVE

[Chumley Jr.]

My tank has no bladder supposedly. The tank air release valve is leaking water when pump is engaged. As I understand it, the pump pumps air and water and the air must be released. The air release valve releases the air. This looks like a tire valve but supposed does not operate like one. Such a valve would be used to pump air into a bladder-type tank. I do not have this. I have a bladder-less tank, so I need the valve that will release air.. Just bought a valve from the clerk who knew exactly what I wanted but sold me an air inlet valve instead. I removed the core and checked it out. Can you sell me what I need???

I would imagine that what you need depends on the particular air volume control that your tank has. The ones I'm familiar with do not release air. The volume control is attached to the tank at a level that the water reaches when at max level. The air control has a line connected to the pump suction. If water gets too high in the tank, meaning there is too little air, then the air control allows a small amount of air to be drawn in on the suction line when the pump runs. That adds air to the tank, until the air/water balance is right again.

Why can't you take this valve part to the local plumbing supply and show them what you need?

I have never heard of what you are describing (but that doesn't mean you aren't right). Without a bladder, most simple systems lose their air because the air can disolve in the water. That valve would be used to add air - not release it. If the valve is on the top of your tank and water is leaking out, that would mean you don't have any air and the pump will cycle too often. (My apologies if what you have isn't what I am picturing in my mind).

replying to Pat, D Forr wrote: You are incorrect. A Bladderless Pressure tank is not common but they do have a pressure relief system. The pump is designed to push air into the system so the tank does not fill completely with water, however, when the air builds up to a certain level the pressure is suppose to be released. I am having the same issue and can't find this relief valve anywhere.

Never saw one with an air pressure relief valve. I have seen various types with air level controls that work by letting air into the suction side of the pump whenever the water is above the level of the control and the control is mounted in the middle to upper part of the tank. That keeps the water to air ratio correct. It has to respond to the water level, not the pressure. You could have

60 PSI in the tank with it all air or with it 99% water, ie water logged. The pressure would still be 60 PSI.

There are always air bleed valves.

[trader_4]

That's an example of what I was talking about.

Which are used to burp systems to get all the air out, air that should not be there. Not for water pump tanks. I suppose there could be systems that always draw some air in on the suction side, then use an air volume control on the tank to let out the excess. But that would be less efficient and I've never seen one.

[Bob F]

Articles I've read suggest that it's fairly common to just have a section of the supply line that drains when the pump is off, filling with air, so a little air comes in each time the pump turns on.

If you have a pump in the ground then you need an air release to let air out of the tank if too much air gets in the tank.we sell the air release in ms

What if the tank has a bladder?

[Goose]

The air level control valve does that job, when the float inside the tank (like a toilet float) drops to low it opens the valve to let air out this valve can also be set to only let out a certain amount, if it lets out to much don't worry the (schrader valve) suction valve will replenish the amount needed in small quaniteys, they work together to keep the system from water-logging or air locked.

If the tank has a bladder, which virtually all new tanks over the last several decades do, then it doesn't have or need an air control float valve.
