Water Well Maintenance Tips & Advice for Longevity.
From time to time the points on the well water pressure switch need to be cleaned as sometimes they either get corroded or small ants or bugs get in the water pressure switch. Often you do not need to put in a new water pressure switch as most of the cleaning the point will make them work as good as new now. Typically the water pressure is adjusted for 40 to 60 psi. The main trick to extending the well pump life is to keep it from starting up (kicking over) a lot. Constant running of the well pump does not wear it out any where near as fast as the motor constantly starting up (that principal pretty much apples to many other electric motors).
One other thing that is very important for good water pressure and to keep the well water pump from starting up too often, is to maintain the air pressure in the water bladder. It should be checked every year. Most homeowners that have well water probably don’t know this. The way to check the air pressure in the water bladder is to first turn off the power to the well and then let the water out by turning on the a faucet. Then use a tire gauge and check the air pressure at the top of the water bladder at the air nipple. It should be at 38 psi when the bladder is drained of water. This air pressure causes the bladder to shrink and keeps the water pressure up so the well pump motor does not start up as often. This will greatly lengthen the life of both the well pump motor and the water bladder. The water bladder can last 30 years, if maintained correctly.
Additionally if you use the well to water the lawn you are better off using a few water hoses that keep the well pump running constantly versus using one garden hose at a time that causes the well pump motor to constantly be starting and stopping.
