Hey Guys, need some help

Water tank pressure release?

About halfway up the tank is the is the pressure indicator which is mounted on a "Brady Bar-125 float (or whatever it is called) I installed a new control box that has the 35/50 off/on set and after about a day it is settled on 29/45 which I think is OK.

My question- The pump turns on and the air release on the tank make a whaling noise and lets air out and some water mist. Other then a small whale being in there, is this normal or can it be adjusted, or is it telling me something is not right.

The tank is a standard galvanized, before all this new utter and bladder stuff came out, it is new though.

Thanks for any light you can give me.

Manny

Good morning Manny,

Your control box pressure's set too high for the air release float valve.
The air release valve is factory preset to release at 20 PSI. Even though the adjusting screw will let you adjust the pressure setting between 0 and 40 PSI it will still blow off like a killer whale. The answer to your problem would be to remove the air relase float valve and either plug the hole or install a bushing that accommodates your pressure gage.
Another option would be to change out the control box to a 20/40 PSI and adjust the valve uo to 40 PSI blowoff. To increase the release valve pressure turn the adjusting screw clockwise.
As it stands now the air release valve is lowering your water pressuire.
Good luck, Tom

Good Morning Tom

I appreciate your help Buddy, I will plug the hole up an this way I will have a place for my pressure gage. That is a perfect trick!

Thanks and have a great day

Manny :)

Just remember that this device is designed to keep the correct balance of water / air--when you plug the hole you will eventually have air through your lines because there is no way for the excess air to escape---recomend that you replace the one that you have with one to match your system----joel

I believe Weller 1 is correct. This is an old style of system. When the pump cuts off, there is an air release valve on the wellhead that allows air to fill the wellpipe. When the pump cuts back on, it pumps that air into the tank to make sure the tank never waterlogs. The air release valve you are referring to is designed to prevent the tank from completely filling with air. That's why its about halfway up. When the water level drops, it releases some air to allow the tank to be about half air and half water. If you remove it, your tank will simply fill with air.

I might be wrong on this part, but it is my understanding that this valve is a float valve. When water drops too low in the tank, the float opens the valve to release enough air to allow the water level to rise enough to cut it off. That fact that it is spraying water is strange, and SB probably has a good point about the valve needing to match the switch.

It is correct that the float (air volume control) located middle ways of the tank is to let out excess air, the air is injected through the pump system, with out the air volume control the tank would eventually fill with air, the size and setting of the (pressure switch) has nothing to do with the air going in or coming out, its all done with a float inside they tank... buy a new one... Maybe $35 Air Volume Control

JP, thanks for the input. However, that post is from 2010. Still, keep posting.
