Also buy a new pressure gauge (less than $10) and a 1/4-in. Be aware that the most common pressure gauge is the "air-filled" type, which are notoriously inaccurate. For an electromechanical switch, the stop point must be at the center of the field of operation. The pump turns on when the system reaches the low pressure cut-in and off when the high pressure cut-in is reached. If I am not mistaken, there is a check valve between the well pump and the pressure tank to prevent back flow to the well, and there should be a check valve on the top of the pump as well. Pressure must be sufficient to force the water through the piping system to the highest outlet and to properly operate modern appliances, continuously and when other outlets are also in use. The standard configuration for most tanks is 28 psi, but it can be less adjusted to adjust the standard pressure switch configuration, which is 20 psi. The valve with the green handle is a shutoff valve to shut off the water to your house.

Installing a well tank that is too small will increase pump cycles, which can reduce pump life, resulting in a costly repair or replacement. However, if the tank pressure has reached the lower cut in setting, or better yet, if the tank is empty, then it is prudent to check the pressure switch. Pressure tanks are usually 2-4 psi under the pressure switch configuration. With the water pump turned on, water is being pumped from the well and into the system, gradually filling up the water tank once again. If less than 25’, use a shallow well jet pump. You will need to take into consideration whether you are satisfied with amount of water pressure in … According to the info you gave, your pump should turn on at 22PSI, and shut off around 42 PSI. what size pressure switch should I put on my shallow well pump? If 25’ – 110’, use a deep well jet pump. The three pressure switch settings for the pressure tanks are 2040, 3050 and 4060. Then turn off the wiring (Photo 1). 20psi, 40 psi). We use cookies to enhance your experience. The three pressure switch settings for the pressure tanks are 2040, 3050 and 4060. You'll need to check what the pressure on your hot water heater's temperature-pressure valve is, but it's probably also fine. 20psi, 40 psi). Draw down capacity is the amount of water that is stored within the tank before the pressure is low enough to turn the pump back on. We use cookies to enhance your experience. Flip the breaker to the pump switch and check it with a voltage sniffer to make sure it’s off. It works just like the heater and thermostat in your house do, only it measures water pressure rather than temperature. or N.C. according to circuit requirements. The first is the pressure at which your pump is lit and the second is the pressure at which your pump is turned off (i.e. Our virtual experts can diagnose your issue (for free!) Changing a pressure switch requires a look at the whole system and also changing the preloaded air pressure in the well tank to suit the new pressure. Things You Will Need. The common settings are either 30/50 or 40/60. A system that requires a switch to activate 140 psi must use a solid state pressure switch with a 150 psi field of operation, or an electromechanical switch with a 300 psi field of operation. Check the well tank pressure gauge to see if it is at least 40 PSI (or the cut-off PSI for your pressure switch model). 20psi, 40 psi).
