Very low water pressure and excessive pump running

it is compressed air and is set around the 50psi mark
the operation is that the pump starts and pressurizes the system
when the 50 psi is reached the pump switches off
you turn a tap on and the bladder starts the water flow at around the 40 psi mark the pump cuts back in and pressurizes the system when you turn off the tap the pressure goes back to the set pressure and turns off
unfortunately bladder systems are out dated and don't allow for more than one tap in operation
There are cheaper and far more precise controllers on the market to control pump operation that also have pump protection where by the pump is stopped if there is a lack of water supply with in 1 minute

Make sure you do not have any excess air in the line. More than likely there is an air (vacuum) leak on your suction line.

Have to set the pressure switch
(instructions are under the cover)

65 # cut off
42 # cut in

Should install a new switch every ten years
& a new check valve before the tank & manifold
assy every 20 years

Without knowing all your variables with well it is hard to say. Bladder tank needs to have 30 psi with no water pressure. It is possible that the screen down the well is restricted and you are only getting that much water. Or you may have clogged impeller in pump.

We don't have a service light on our pump, but usually when our is playing up it's because the pump is struggling to push enough water through - for example if the filter needs changing or if the skimmer isn't receiving enough water/water level is too low.

Varem pressure tanks are simple pressure vessels. They have a chamber where the fluid comes in and a bladder that is pressurized on the other end that the fluid pushes against and compresses the air or other gas that is inside the bladder. When the pressure on the fluid line reaches the pressure switch setting, the pump shuts off and the gas pushes the water back out of the tank (if it is being used) until the pressure switch lower limit is reached and the pump kicks back on, pushing fluid back into the tank. This cycle continues until the fluid is no longer being allowed out of the system.

The bladder pressure is set when the system is empty of water and is set to a couple of pounds less than the low pressure cut on setting, that keeps the bladder from pushing all the fluid out of the tank before the pump comes back on resulting in a zero pressure moment which with some pump switches means it shuts down and has to be manually restarted.

The check valve is bad. When the system builds up pressure and shuts off the check valve prevents water from dropping back down the well line. When the check valve goes bad water drops back down the well line and siphons water back out of the well tank causing the switch to kick on and off constantly. The check valve will between on the well line coming from the drop pipe. It may be making a constant rattling noise as pump is running. Replace the check valve and you should be fine. Also check the pressure in bladder tank it should be 2psi below the "cut-in" pressure for the switch.

the unit has a hi pressure safty switch on it, probally has a red push button on top. when the water slows down or stops the hi pressure trips to shut unit down to prevent compressor damage, the switch does not reset it self, find it in the outdoor unit and reset it, let me know. thanks wally.

pressure switch,look under cover tells you how too set there's low set and high set,look at pressure guage should click on at 30psi shut off at 50psi, adjust to this, just be careful don.t get shocked'power goes to switch for your pump. that would be first thing i'd check.

What's the problem??
