How do I adjust the pressure switch on a small water well pump, there are two adjustment screws one is larger than the other.
Many thanks, M. Ruen

If you have a square "D" control box,(see image) let me show you how.
First turnoff the power at the breaker box, then pull the cover off the pressure switch and you will see two spring loaded bolts secured with nylon nuts. One tall, one short. To increase the cut in pressure, turn the nut on the tall bolt down. To increase the cut out pressure,(that's the one that will give you more pressure) turn the nut on the short bolt down. This should give you the additional pressure you desire. Good luck Tom

The pump comes on for a few seconds every time we use the tap, everything seem normal except when using water the pump kicks on for seconds. How do I correct this?

Could be a bad pressure tank. Your tank should have a little air valve at the top, like found on a tire. Push the valve stem down for a few seconds to release air. If you get water, then you have your problem. Only solution... new tank. To get by for a few weeks, you can refill the tank's air charge. With power off, drain pressure to zero by opening a low level faucet. I like to use an air tank to add some pressure to the tank to the tune of 10 or 15#. Turn your power back on and you should be in business. Just be aware that the problem will come back in a few weeks. The only permanent cure is a new tank.

Check that tank and let us know what you find.

Emptied tank & changed air control valve & everything is back to normal. My tank did not have an air valve. Thanks for you help. Tc

Ah. You did not have a bladder tank. They have become so common that I have gotten to where I don't even mention the galvanized tanks. My bad.
