You can pump up the tank okay, but it won’t hold the pressure. Solution: Check the pump gasket at the top of the pump cylinder (tank); it may be cracked or damaged and not forming a seal with the tank cap. Replace the pump cylinder gasket and make sure that it fits tightly around the top of the pump cylinder.
Chances are there is dirt or debris somewhere in the discharge line. Most likely the nozzle is plugged. RELEASE THE PRESSURE by SLOWLY opening and removing the pump. Then, unscrew the nozzle cap and check to see that it`s clear (see diagram below).
Check the Tube

Instead, it`s likely your spray bottle isn`t spraying properly because the tube has disconnected from the nozzle. To check this, poepping says to push down on the sprayer. If you can press down with ease, but the product isn`t coming out, it`s likely a disconnect with the tube.

Running pump stopped
ANSWER : I assume that the plug in is working properly. Always check power supply first. Is there a GFCI circuit that it is plugged into. Then check the pump to make certain it us turning. How long had it been on before unplugging it. It could be worn out. Sometimes it takes a jolt to start the motor again. How big is the motor. Possible bad capacitor. Could be a solid state motor, then it’s bad. Is it a magnetic motor, that could be turning the wrong way.

Pump works for about 20 seconds then stops for 40 seconds then starts again.
ANSWER : This sounds as if motor is overheating and the thermal switch is stopping it (why it restarts by itself) if a pump is overheating then a few reasons need be looked at , is pump encountering higher viscosity’s than designed for and is having trouble moving liquid fast enough , is distance pump has to lift liquid over what it’s designed to do most of these pumps use liquid it’s moving to provide cooling to pump , is liquid it’s moving warm/Hot allready if so use different type of pump (non submerged) and last but not least is pump worn out and is failing moving parts wearing together make heat !!! ?

The pump will not continue to run after starting, it runs for 5 seconds and then stops, until the next attempt to detect water, the pump is sitting in three feet of water. The pump will not continue to run after detecting water.
ANSWER : CLEAN AIR LOCK HOLE

The well pump is running, but no water is supplied to thr irrigation lines. once I put water in the pump housing by removing the pump guage the pump pumps water through the irrigation lines. when it shuts down, iloose the prime again. what should I do?
ANSWER : Sounds like you have an air leak. First check your fittings, next carefully run water over the pump seals (avoid getting water on the motor or you’ll hurt yourself and the pump if not worse) the pump will prime if the leaking seal is covered with water. Take your time and be careful and it should only be a matter of a loose fitting or simple seal swap.

Pump runs for a few minutes becomes hot and stops then starts again
ANSWER : Pump motor is overheating or drawing too much current and the safety is shutting the motor down. After a period, it automatically kicks back in (quite common). Replace motor (and safety which probably comes with, or is actually contained inside motor).

It has lost it's prime – Sta Rite Ds3hf 1.50 Hp Self Priming Irrigation Pump
ANSWER : Without more info it’s hard to say. This could be something as simple as a dirty lid “o” ring, if it is streched out or cracked you will need a new one. If not you can clean with dish soap then when you relube “o” ring use teflon or silicone grease then wipe excess off as this excess will collect dirt, also clean lip of pump pot also. If this is not the problem then you may need to replumb pump or replace seal. When you loose prime if the pump runs for any lenigth of time the water left in pot will overheat and cause plumbing to warp or seal falure.

I have a pressure booster pump installed which turns on automatically when we open the tap and turns off by itself when we close the tap, but when power goes and comes back(common in india), the pump will turn on even with no tap opened and does not turn off automatically and goes on running, some kind of airlock problem I think, when we just shut off and on water input several times, it again starts working well
ANSWER : Check to see if the output pipe has water in it when the pump swutches off the pump needs to be primed at all time what we normally find cases like this is the pump is higher than the supply or there is an air pocket on the output where the pressure sensor is
