well tank problem
I have a well that has an above ground pump. There is a bladder tank that holds about 2 to 3 gallons of water. Lately I noticed the water pressure cycling too much, like about 3 times in the time it takes to fill a one gallon jug. Checked the bladder tank and the pressure at the tank was about 60 psi. Cut the well pump off and drained the pipes to the house. Then let air out of the tank to the recommended 2 psi below the cut in pressure switch to about 38 PSI. Worked better for a day or so. Then noticed the short cycling again. Cut well pump off and drained water pipes. The bladder tank was back up to almost 60 psi. I have done this several time. Just how is that bladder tank making air ? There does not seem to be any water comming out of the air valve at the top of the tank that normally the bladder keeps the water out of. Looks like I should be getting water out of the valve if the bladder has a hole in it. |

I've had to have my tanks replaced about every 10 years - the last one even though it seemed OK. |

Normally The tank should not gain or loose air. If anything it may leak out a small ammount of air just like your car tires. I just can not undrestand why I have to let air out to matain the 38 psi with the pump off and the water pipes open. It would be similar to having to let air out of your car tires just to matain the normal pressure. That tank is somewhere around 5 years old. I am not sure how much it should hold, but the tank is about 3 to 4 feet tall and a foot and a half in diameter. |

I think this tank is suppose to hold about 3 to 4 gallons of water. There was one about half this size or smaller when I bought the house about 15 years ago. It went bad, but the bladder had burst or had a hole in it as water would come out of the air valve at the top when the stem was depressed. So far this tank has not put out any water through the air valve so I am thinking the bladder should be ok. I can see adding air due to slow leaks over a number of years, but can not see how in a day or two it can gain air. |

That would be if the bladder has failed and there is a small leak in a suction line from the pump to the well, if it's a conventional pump. Air can't be getting into a bladder that is intact and with the tank drained, that's the only pressure you're measuring. What happens if you slowly let all the air out of the bladder, with some pressure still in it? If the bladder is intact, no water should come out. Haven't tried that, but seems like a way to test for whether the bladder is intact or not. |

Haven't tried that, but seems like a way to test for whether the bladder is intact or not. The bladder may have failed. That is the only way I can think of the tank holding pressure with the water line open . I guess it could have a small hole in it that is not letting much water in for now so it will not have any water comming out of the air valve. It sure puzzles me as to how I can let the air out to 38 psi and the next day it will be back up to 60 psi, but no water comming out of the air valve. I think I will replace the tank and hope that solves the problem. I don't see any other way out. Let us know how you make out. Over 2 years ago when I needed a new well the well digger put in a new bigger tank which he said old tank was failing but the plumber who first looked at my problem said pressure was OK in the old tank. The old might have been 10 years old and that was about all the lifetime I was getting from them. You are lucky, I usually end up replacing them at around 5, just about when the warranty is up. Funny how that works. I did have the original, true bladder, tank (fiberglass vessel) that came with the house and it lasted over 20 years. I tried to just find another bladder but it was an exercise in futility. I still have the tank. |

If the bladder had a hole in it, I would think that the tank would work ok if it had air in the top and I may need to add air from time to time. Just do not see how it can keep building pressure and I keep letting air out. |

Have not had a well problem with the new one but if I do I will use the well contractor as problem could not be solved by the plumber. At this very moment I have an appliance repairman looking at our electric stove which has been tripping breaker. Last week he could not find the problem and blamed the breaker and suggested we get an electrician to look at it. Electrician could find nothing wrong with the box or the breakers. |

I have been here for aboutg 15 years and have no idea how old the first one was as this house was about 20 years old when I bought it. Replacing the tank would be easy for me, but as I have gotten older I would rather pay a reasonable ammount to someone else. I hate plumbing more than anything around the house other than painting. Many companies have research teams to determin how long something will last. The they warrenty the items for about 10 % less. Plumber told us once that the main difference between water heaters with longer warranty was the higher price. |

You could have air getting into the system before the pump and getting compressed into the water section of the tank, displacing water from the tank. |

says... I found a youtube video that shows the same thing my well pump system was doing. More air pressure building up in the bladder tank. It shows the bladder tank gaining air pressure when the bladder is bad. I still don't see how it can gain air pressure with the pipes open, but it does. Maybe if I let all the air out of the tank by the air valve water would start comming out. Iment to include the youtube link. https://www.youtube.com/watch?v=L9KKJxdqJsU |

It's just a plastic bag, inside a tank, not exposed to weather, UV, etc. I recall seeing ones, maybe they all have it, with a good size plug on top that the air fitting comes out of. I assumed you can get a new bladder and replace just that. Which would be a lot easier and cheaper, assuming the plug will come out and that's what it's there for. Also I still can't fathom how a broken bladder results in the tank gaining air. I would expect it to lose air, as the air is slowly absorbed into the water. |

As far as stove, I had not mentioned we needed hinges on door replaced and service tech decided to change stove heating element which was apparently failing. With parts and repairs including electrician visit cost about half the cost of the stove. Not happy with Whirlpool stove only 2 years old. We had done nothing to cause hinges to fail. |

Maybe the air pressure builds up from a small hole and I did not leave the water line open long enough for the air to bleed out of the bladder. When I was a kid our water tank had a standard Schraeder valve. When the flow would get sluggish or the pump was coming on frequently we would drain the water and pump it up with a tire pump. I didn't know they had bladders until a few years ago they changed them out in the communal well house. While the bladder itself could be replaced apparently it cost as much as the entire tank and wasn't worth the hassle. |

You know they are bad if the line pressure goes to zero (pump off, valve open) and there is still water in the tank. Mine aren't screwed down and there is enough flex in the pipe to bump it off the floor. You know right away if it is full of water by the weight. |

I assume it is just the constant flexing and if you are not diligent about checking the air the bladder gets over extended. They are replaceable. The problem is finding the bladder if it is a bladder tank. Some are diaphragm tanks and you can't replace that. I have never found a bladder for a tank when I needed one. My tanks are diaphragm tanks now. Also I still can't fathom how a broken bladder results in the tank gaining air. I would expect it to lose air, as the air is slowly absorbed into the water. I thought about this for a while and the only thing that makes sense is that there is some kind of pocket that holds water, even when the system is at zero pressure and that reduced volume maintains more air pressure. That's why I said lift up that tank and see if it is waterlogged. |

When I was a kid our water tank had a standard Schraeder valve. When the flow would get sluggish or the pump was coming on frequently we would drain the water and pump it up with a tire pump. I didn't know they had bladders until a few years ago they changed them out in the communal well house. While the bladder itself could be replaced apparently it cost as much as the entire tank and wasn't worth the hassle. That was my take on it although if I could find the right bladder for the fiber glass one I have I would do it. That thing was tough and lasted a real long time. |

I assumed you can get a new bladder and replace just that. Which would be a lot easier and cheaper, assuming the plug will come out and that's what it's there for. Also I still can't fathom how a broken bladder results in the tank gaining air. I would expect it to lose air, as the air is slowly absorbed into the water. I guess they fail because of all the flexing. One side is next to the water so if the water has something in it that could also make them fail sooner. I can not think of how it makes and ar pressure. That is what had me puzzled before I found the video and another showed his gaining air. I know on the older tanks with out a bladder people often had to add air. Maybe the air pressure builds up from a small hole and I did not leave the water line open long enough for the air to bleed out of the bladder. I will guess your bladder has a pinhole leak in it. When the water pressure is at its max, a small amount of water leaks into the air chamber. It stops leaking when the air chamber gets up to the 60 psi you have observed. When the water side pressure it lowered, the leak seals itself. The air side is left at the system max pressure but is still mostly air. I believe your problem will be solved when your tank is replaced. |

I have a well that has an above ground pump. There is a bladder tank that holds about 2 to 3 gallons of water. Lately I noticed the water pressure cycling too much, like about 3 times in the time it takes to fill a one gallon jug. Checked the bladder tank and the pressure at the tank was about 60 psi. Cut the well pump off and drained the pipes to the house. Then let air out of the tank to the recommended 2 psi below the cut in pressure switch to about 38 PSI. Worked better for a day or so. Then noticed the short cycling again. Cut well pump off and drained water pipes. The bladder tank was back up to almost 60 psi. I have done this several time. Just how is that bladder tank making air ? There does not seem to be any water comming out of the air valve at the top of the tank that normally the bladder keeps the water out of. Looks like I should be getting water out of the valve if the bladder has a hole in it. Personally, I'd just replace the tank but if you want to prove to yourself that the diaphragm is bad... Bleed the air from the air side of the diaphragm and unscrew/remove the Schrader valve. Shut off pump breaker and drain the tank. Remove tank and turn upside down so Schrader valve is on bottom. I suspect you'll see water dripping from the Schrader valve opening. |

There does not seem to be any water comming out of the air valve at the top of the tank that normally the bladder keeps the water out of. Looks like I should be getting water out of the valve if the bladder has a hole in it. I found a youtube video that shows the same thing my well pump system was doing. More air pressure building up in the bladder tank. It shows the bladder tank gaining air pressure when the bladder is bad. I still don't see how it can gain air pressure with the pipes open, but it does. Maybe if I let all the air out of the tank by the air valve water would start comming out. Anyway I have a plumber comming out Monday morning to replace the tank. While it is simple enough to do it, I just hate plumbing so bad I am willing to pay a man a reasonable ammount to do it. Found some paper work on the tank and it is 6 to 7 years old so I guess that is about what others are getting out of their tanks. Makes no sense to me that these tanks fails so quickly. It's just a plastic bag, inside a tank, not exposed to weather, UV, etc. I recall seeing ones, maybe they all have it, with a good size plug on top that the air fitting comes out of. I assumed you can get a new bladder and replace just that. Which would be a lot easier and cheaper, assuming the plug will come out and that's what it's there for. I assume it is just the constant flexing and if you are not diligent about checking the air the bladder gets over extended. They are replaceable. The problem is finding the bladder if it is a bladder tank. Some are diaphragm tanks and you can't replace that. I have never found a bladder for a tank when I needed one. My tanks are diaphragm tanks now. Also I still can't fathom how a broken bladder results in the tank gaining air. I would expect it to lose air, as the air is slowly absorbed into the water. I thought about this for a while and the only thing that makes sense is that there is some kind of pocket that holds water, even when the system is at zero pressure and that reduced volume maintains more air pressure. That's why I said lift up that tank and see if it is waterlogged. I forgot about diaphragm tanks. Nice images here to look at differences between them. https://duckduckgo.com/?t=ffsb&q=bla...l+tanks&ia=web -- Tekkie |
