Like I mentioned before, I worked in this field for MANY years and have seen it all! If your pump is cycling quickly ie off and on off and on at a rapid pace, your tank is probably the culprit. The tank should be almost empty of water because above the diaphram there is air. The diaphram separates the air from the water. Just in case you are being scammed, tap the tank and see if in fact the tank feels full. If not, take an air guage and check the air valve on top. It should read 2 lbs less than your cut-in pressure. In Mexico, the usual cut in pressure is 20 lbs but with newer places they are jacking it up to 30lbs per sq. inch. The high end is 20 lbs/per sq. inch higher than the low end. Like I said, I'd have to check it to know if your plumber knows for sure. It could also be a faulty pressure switch. If the cut in pressure is NOT at least 18 lbs per sq. inch, take a bicycle pump or an electric air pump and put that amount of air into the top of the tank. All this info is based on the fact you actually do have a diaphram tank. Good luck.
