Cycle stop valve problems
Replacing the water tank and bad diaphram symptoms
Submersible pumps and motors that were sold to homeowners until the early 1970s were designed to last. Pumps and motors used to last 20 to 30 years since they were designed to withstand the abuse of cycling on and off. Companies have been reducing the length of motors and replacing lifetime ball bearings with short-lived bushings since the 1970s. The heavy-duty brass impellers on the pumps have been replaced with all-plastic impellers. These improvements were made to minimize the expected life of pumps and motors, not to boost them. Pumps and motors are now built with “anticipated obsolescence” in mind, rather than the consistency necessary for a longer service life.
Most pumps and motors on the market today have an estimated life of around seven years. This means that some will live for 14 years and others will only live for two. The number of times the pump cycles on and off is normally what decides how long the pump and motor will work for the average homeowner. The bigger the pressure tank and the less water used, the less cycling on and off can occur, extending the life of the pumps and motors. The shorter the life of pumps and engines, the lower the pressure tank and the more water used.

I had a leak in my well supply line under the slab in my garage two days ago. I broke open the slab and patched the poly line after a lot of swearing and a huge mess. All was well after that, and the machine was pressurized, though at a lower pressure than normal. I wanted to fiddle with the settings today.
My pump was running nonstop this morning, and the machine was not pressurizing to hit the cutoff. When I turn on the pump, it quickly reaches around 30 PSI and continues to run whether or not a faucet is turned on. Since the pump is not pressurizing and does not meet the 60 psi cutoff, it does not shut off.
How to make your water well pump last longer
Pump Regulation Valves: Do You Have Any?Resting Pumps and Motors: Do You Have Any? Pumps are designed to operate continuously and do not require any downtime. What Is Soft-Start Equipment? Since the CSV has a mechanical soft start and stop, a soft starter can be used to reduce the end rush. If You Have Back Pain? Pumps are not harmed by back pressure. Pumps are just tricked into thinking they are in a deeper well. Is There a Minimum Flow? Pumps only need a small amount of flow to stay cool. Derated motors need very little cooling as well. What is cavitation? At low flow, recirculation rather than cavitation occurs. Impellers with a high tensile strength can withstand recirculation wear.
Back Pressure and Differential Pressure are two examples. Enable the pump In PSI, a dead head equals 250 PSI. PSI 250 – 65 = 185 PSI Static Water Level 150′ = PSI 250 – 65 = 185 PSI Back pressure or full inlet pressure 185 PSI will be applied to all pipe and fittings prior to the CSV. If the CSV is set at 60 PSI and the inlet pressure is 185 PSI, the differential pressure through the CSV is – 60 = 125 PSI. The differential pressure must never exceed 125 PSI.
Using two or more valves to stair step the pressure down to the necessary pressure if the differential pressure is greater than 125 PSI. For example, if the differential pressure is 200 PSI, the maximum inlet pressure is 250 PSI, and the device only needs 50 PSI, the differential pressure is 200 PSI. The first valve is adjusted for 150 PSI and sees 250 PSI. The second valve is adjusted for 50 PSI and sees 150 PSI. Each valve receives a 100 PSI differential as a result of this.
Troubleshoot: water well pump starts too often (rapid
A Constant Pressure Valve, or CPV, is a pump control valve that converts any normal, constant speed pump into a variable flow pump. A Constant Pressure Valve, which is attached to the pump’s discharge, automatically chokes back the pump’s output to meet the user’s water demand. The amount of energy used by a centrifugal impeller inevitably decreases as the number of gallons per minute used decreases without increasing the pump’s speed.
Regardless of the amount of water used, the CPV ensures a constant pressure for the water user. The CPV is entirely mechanical and does not require any circuitry. Without variable speed monitors, massive pressure tanks, or water towers, large pumps can now handle very small flow rates. Pumps with a Constant Pressure Valve can operate safely from as little as 1 GPM up to the maximum output of the pump.
Stopping pump cycling, eliminating water hammer, extending pump life, and saving energy are all benefits of the CPV. The CPV can maintain a constant level in elevated tanks and water towers, or supply water to a city of 40,000 people from a 44-gallon tank.
