Question about Apple Mac mini G4 Desktop

1 Answer

Shaired well My neighbor removed his bladder tank and pump now my system pumps water 350" up to the surface and 100" to my house and an additional 400" to my neighbor's house. Should the removal of his pump put additional strain on the well pump, if so what should be done? The model or brand name is not to be found, I do know the system is very old. It could very well be a home made system. The tank has no bladder, the air valve is on the T at the bottom and this leads me to believe there is no bladder. the tank is 24" wide 5' tall this has been working well until recently the air pressure doesn't seem to last nearly as long as it did before the second pump was removed from the system.

What is bladder tank?


A bladder tank is a water storage tank that is used to allow a pump to compress air inside the tank. Water can't be compressed so the tank is built with a bladder or balloon inside that allows the pump to be able to build up pressure inside the tank. This allows a pressure switch to turn on or turn off the pump. Typically if the bladder goes bad inside the tank the pump will cycle rather frequesntly.

High Electric Bill due to Well Pump Cycling On Frequently


The short run time of the pump indicates very litttle water volume is needed to reach to turn off pressure. To me this indicates you may have two problems. There is a leak somewhere in the system that allows the pressure to drop to the turn on point. Any check valve will fail eventually so barring any other leak that is your problem. I would think only one check valve is needed in the system so the second one may have been added to crutch the first one leaking. Normally the one check valve is placed on the pump before it is attached to the well pipe. The pump must be removed from the well to accomplish the replacement.

The second problem has something to do with the storage tank. If the pumps runs whenever you open a faucet or in your short cycle situation, then your tank is way too small or it is "water logged". Assuming it has been sized correctly, which means at least 20 gallon capacity then air needs to be added to the tank which will compress when the pump adds water until the high pressure setting is reached. When water is release to the house the air will expand until the low pressure setting is reached and the cycle repeats. The point here is that a significant quanity of water flows between pump cycles.

If your tank was installed in perhaps the last 20 years then it is likely a bladder type whitch contains the water so it never comes in contact with the steel tank, preventing internal corrosion and leaching of metals into the water. If the bladder has failed then the formally isolated air will have been absorbed by the water and your short cycling condition develops. That is what happens in non bladder tanks so air needs to be added periodically. I think all bladder tanks have a car tire like valve stem attached to the tank so that the opperating pressure can be set by the manufacture. The valve stem rairly leaks so bladder failure causes the loss of the air in the tank. There should be a label on the tank specifying the factory pressure. Use a tire gauge to test for the proper pressure. Add air if it is below setting.

How do you replace a pump pressure switch and or tank?


i would check the bladder first the switch only turns it on and off the bladder helps with the volume of pressure there is a air fitting on the top if the bladder is bad push the valve with a screw driver tip water would spray out with a tire pressure gauge set the pressure a couple pounds highter than the turn on pressure thats free to try you can't bring back parts

Loss and intermittent well water pressure. Pressure tank reads between 30/45 psi. Turns on when pressure is relieved.


Sounds like you have a waterlogged tank. If it is a tank with a bladder in it you might have to replace it. Does it have a stem on top to put air in? if so it is a bladder tank. One thing to try: turn off the circuit breaker, open the hose bib close to the tank and let all the water drain out, when empty check the air in the bladder with a tire gauge should read at leaset 20 psi. Add air if needed, close hose bib and turn circuit breaker back on, if tank is leaking this should help temporaly, if it starts doing the same thing in a short time you will need to replace the tank.

Ao smith 1 horse house water pump. water pump only fills tank half way to 3 /4 . pump does not stop running.. water pump leaking a little water out of water valve spiot


Hi, W/D here.
The tank has to have an air cushion in it for the water to be delivered as water is not compressible. Ideally, the water is expelled from the tank without air leaving the tank, and then the pump starting to refill the tank. The air in the tank is supplied either by an air bladder installed in the tank, or by an air injection system where a little air is injected into the tank every time the pump runs and shuts off.
A little leak at the pump is not a big deal, but should be capped off or the faucet repaired/replaced at your earliest convenience. Ideally, the water level in the tank should be closer to 80%; so if you have an air injection system, you might let a little air out of the tank (if you have a top valve), and this might cure your cycling problem. With the tank level as is, you are probably getting some air in your lines into the house. If you have an air bladder in the tank, the required pressure of the bladder, with no water in the tank should be on a sticker located at the schrader valve on the top of the tank (A schrader valve is similar to the air inlet valve on a bicycle tire). The ones I am familiar with are set around 28-29 psi. If you have an air injection system, it may need to be replaced. If the costs are close, I would elect to go with a bladder tank, as I've found that they eliminate many of the problems associated with the air injection type.
Fix or cap the faucet so you have no leaks showing at the pump or tank. Catch the pump running, and wait for it to shut off. When it does, close the discharge valve to the house and wait. You may need to trip the breaker for the pump. Watch the pressure gauge. If the pressure falls, the problem is with the well, and you may need to pull the inside well supply line from the casing and make repairs at the foot. My experience has been that it is better to replace the leathers, jet valve and foot valve all at once than to hope they hold if I repaired only one part.
If the gauge holds after 10 minutes, open the valve. If the pressure falls, the problem is on the house side of the valve.
Resolve any issues on the well before checking further, as that's where most well problems originate.
Adjust your tank level and pressure. If the pump continues to cycle, you may need to replace your pressure switch.
Best regards, --W/D--

The pump goes on and off repeatedly


The pump should only run if you are using water. If you have a leak it will cycle on and off. If it only cycling fast when you're using water, you may need an expansion tank, sometimes referred to as a bladder tank for newer style. If you have a "bladder" tank , the bladder may be leaking and lost it's air charge. This bladder will have an initial air charge, and when the pump runs it will compress the bladder even further. When the pump shuts off the bladder is compressed. When you begin to use water, mainly low flow like one faucet, the bladder will begin to expand expelling the water from the tank until the pressure drops below that of the pump pressure switch. This makes the pump start and stop fewer times.

How do you stop a 12 volt water pump from short cycling when the outlet tap is on


Is this in a camper? You can either increase the flow to match that of the pump, or install a "bladder" tank in your plumbing system. A small air bladder tank is not too expensive. You charge it with a min of air pressure. When the pump comes on, it will pump the water, and this will compress the bladder raising the pressure in the bladder. When you begin to use the water, the bladder tank will begin to supply the water, when the pressure drops sufficently enough for the pump to come on the cycle will repeat, allowing the pump to start and stop with a delay in between instead of off-on-off-on etc.

When adding air to a pressure water pump ,i


Sounds like the bladder is gone or inproper air pressure in water storage tank.

Bladder goes bad check it out with step 1
1-
One way to check for sure with everything hooked up. The air valve on top of the tank if pressed you will get water out of the valve which should be only air. This will let you know it should replaced.

If Tank bladder is low in air and not water coming out.

2-If it checks ok put an air gauge to tank to check the air pressure, with a standard 40 gal tank you will have 28 psi of air in tank for it to function properly.

Why is the pump cutting in so much


Check your water pressure tank air pressure, turn off pump, drain off all water pressure and using a air pressure gauge check pressure at the schrader valve on the water pressure tank. It should be 2 lbs below pump cut-in pressure, they come factory charged at 30 PSI...works for most residential systems. Most likely you have a bad bladder in pressure tank.

Other possibles are a broken line between pump and pressure switch/pressure tank or bad pressure switch.If you have a pressure gauge on the water system(should have one near pressure switch) see if it is cycling at the right points if it is the switch is good. If pressure is dropping with NO water uasge in house you have a leak.

Most likely a bad pressure tank bladder is the problem.

Flotec 42 gallon water tank - short cycling and changing water stream...do I need a new tank or could it be another problem?


These holding tanks are pre charged with air which in turn pressurizes the water. The tank has a bladder and an air valve on top. The pre charge ,over time, loses pressure, and the tank has to be pressurized again.
  • The well pump needs to be turned off.
  • The water has to be drained from the tank
  • Air is put into the tank from the air valve on top of the tank, and is measured with a tire air gauge.
  • The pre charge pressure is set to two psi below the pump cut in pressure.
  • In other words if your pump kicks on at 30 psi, the pre charge pressure is set at 28 psi. If the pump kicks in at 20 psi, the pre charge is set at 18psi, etc.
  • After you pressurize the tank, turn water back on.
  • If water comes out of air valve on top of tank, then the bladder is ruptured and you need a new tank.
  • Hope this helps!
