Davey presssure pump when switched on b4 tap is opened the pump does run stop run stop run stop between each cycle small squirt of water escapes from pressure tank at the clamped junction

If your pump is turning on by itself every 10-15 minutes for a brief period when no taps are open, it may indicate a potential issue with the water system or the pump itself. Here are some common causes and troubleshooting steps:
1. **Pressure Tank Issues:**
Check the pressure tank in your water system. A malfunctioning pressure tank or a tank with inadequate air pressure can cause the pump to cycle frequently. Ensure that the pressure tank is properly pressurized according to the manufacturer's specifications.
2. **Water Leaks:**
Inspect your plumbing system for any leaks. Even a small, slow leak can cause the pressure in the system to drop, triggering the pump to turn on periodically. Check for visible leaks and listen for any sounds of running water when all taps are off.
3. **Faulty Check Valve:**
The pump may be turning on due to a faulty check valve. The check valve is designed to prevent water from flowing back into the well or water source when the pump is off. If it's not functioning correctly, water may flow back, causing the pump to cycle.
4. **Waterlogged Pressure Tank:**
If the pressure tank is waterlogged, it can lead to frequent cycling of the pump. You may need to drain and recharge the pressure tank to resolve this issue.
5. **Faulty Pressure Switch:**
The pressure switch is responsible for turning the pump on and off based on water pressure. A malfunctioning pressure switch can cause the pump to cycle erratically. Check the pressure switch for proper adjustment and functioning.
6. **System Overpressurization:**
Excessive water pressure in the system can also cause the pump to cycle frequently. Check if the pressure relief valve is functioning properly and that the system pressure is within the recommended range.
7. **Electronic Control Issues:**
If your pump system has electronic controls, there could be issues with the control panel or the pump's electronics. Check for error codes or indicators on the control panel and consult the pump's manual for troubleshooting steps.
8. **Professional Inspection:**
If you're unable to identify the cause of the issue or if the pump continues to cycle unexpectedly, it's advisable to seek the assistance of a professional plumber or pump technician. They can perform a more thorough inspection and address any underlying problems.
Addressing the issue promptly is important to prevent unnecessary wear and tear on the pump and to ensure the efficiency of your water system.

if the pump is delivering to the hose tap then it is working
there has to be a problem in the plumbing and control arrangement to the house taps for there to be no pressure at the house
possible tap turned off to the house circuit
Is the pump big enough to supply constant pressure /flow to more than one tap
what sort of pressure control unit is there on the pump
what distances and head heights are involved from the water level in the tank to the house taps
Is there water flow from the house taps but not at pressure
the pump should be able to maintain at least 35psi with at least 4 taps running

possible it is a jet pump that has a return hose back to the foot valve to assist the pump to lift the bore water higher to work the pump
if that is the case ,when you turn on the tap on the pressure to the lift jet is reduced and so the pump cannot lift the water from the bore --it runs out of water
the fix here is to restrict the flow out of the tap so that jet pressure is maintained--- don't turn the tap on more than 1 turn
the reason is the lift height is too great ,indicating that the bore water level is lower than it normally is

Check the turn nob and the corresponding switches.. if theres power going to the pump the something from the setting to the pump is broke. Id assume the contacts are not connecting thus skipping the drain cycle or youve got a bad switch

Start dishwasher. Stop after a minute or so. Check the water level in the tub. On a older model I would expect about 2 inches of water in the tub. About 1/2 inch or so below heater.

If water OK than I assume you can hear the pump running.

If pump running and enough water than I would assume a blocked wash arm.

• First rotate by hand and make sure that it doesn't bind or interfere with rack.
• Check carefully the holes at the ends of the arm looking for debris that collects. Seeds and such love to collect at the tips preventing the jet of water that provides the rotation force from escaping. Use small tweezers to grab debris and pull through hole
• Blocked water return screen. Look for clear plastic etc that covers the return of the water to the pump sump.
• Place small cups right side up in upper and lower rack. Cycle machine for a minute or so. Confirm cups are filling with water!!

If all checks OK than try running water at sink for several minutes to confirm water is very hot. Start cycle knowing inlet water to dishwasher is hot. Evaluate results.

Push it back onto nipple-should hold rarely come off-change tubing if too loose.Put a small clamp.easy as pie.

I take it that the system is a pressurized tank system, If this is the case, the tank should be drained to about 1/4 full by opening the valve at the top of the tank with the pump switched off. open a low lying tap and let the water drain out, when the tank is at the 1/4 level, close off everything and switch on the pump. It should now fill the tank to about half and the pump should switch off. If it does not yu will need to set the differential pressure switch or if damaged, replace it.

well the part that tells the water to stop running in is the pressure switch if the water valve is working properly so disconnect the power and if the water continues to run in it is the water valve just replace it

If it fills with water and starts the cycle and the water keeps running in then your water inlet valve on the back where the water supply comes in is sticking. It needs replacing.

If it overflows and don't start the cycle-
Your pressure switch stops the water and allows it to start the next cycle. It's a switch either in the control panel or at the top of the tub with a small tube connected to it which goes down between the inner and outer tube. As the water level increases the air in the tube is compressed until there is enough pressure to make the switch stopping the water from filling. This tube can get clogged and the switch won't work. Remove the tube and clean it out. Blowing on the tube when it's still connected to the switch will make the switch if it's working and clear.
