What pressure switch do I need for my well?

Asked by: Valerie Powers

Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi. If your well tank is on a 40/60 pressure switch, your pressure setting should be 38 psi.

How do I know what size pressure switch for well pump?

Pressure Switch Setting

The three pressure switch settings for pressure tanks are 20/40, 30/50, and 40/60. The first number is the pressure at which your pump turns back on and the second number is the pressure at which your pump turns off (i.e. 20psi on, 40 psi off).

Do I need a 30 50 or 40 60 pressure switch?

For a single level home or a two story home without water fixtures on the 2nd floor a 30/50 PSI setting may be sufficient. For two or more levels with water fixtures on more than one level you may want to use 40/60 PSI setting. It’s easier for a pump to supply the lower pressures and it’s less strain on old plumbing.

How do I know what well pressure switch I have?

There are two numbers on the switch that denote at what point the switch cuts in and cuts off. For example, a 30-50 pressure switch indicates the pump will kick in at 30 psi and cut off at 50 psi. You can adjust these numbers as needed based on what you need out of your water supply.

What is normal psi for well pressure tank?

Normal well water pressure should fall between 40 and 60 psi, so if your pressure is outside the normal range, adjust the pressure switch.

Is 70 psi too high for water pressure?

How High Is Too High? The ideal water pressure level is between 50-70 PSI. If your water pressure goes above 70 PSI (even occasionally), you should install a pressure regulator to your main water line.

Can I put a higher pressure switch on my well pump?

You can raise the pressure switch-points by adjusting the pressure switch. It’s not uncommon to run at 60/40, and 70/50 is also possible. The limiting factors are: Your pressure switch (though as Ed says, most go to 90 or so)

Is a bigger well pressure tank better?

When it comes to pressure tanks, bigger is almost always better. A pressure tank creates water pressure by using compressed air to bear down on the water.

Is 40 psi good water pressure?

Normal water pressure range

In general, residential water pressure ranges between 45-80 psi (pounds per square inch). If your water pressure is under 40 psi, it’s considered low. A psi between 20-30 is considered very low, and under the minimum water pressure required by most building codes.

What is good well water gallons per minute?

The Water Well Board suggests that a minimum water supply capacity for domestic internal household use should be at least 600 gallons of water within a two-hour period once each day. This is equivalent to a flow rate of 5 gallons per minute (gpm) for two hours.

What is a normal gpm for a house?

about 6 to 12 gallons per minute

The average household needs 100 to 120 gallons per person per day, and a flow rate of about 6 to 12 gallons per minute.

Is 20 gpm good for a well?

You could have a great well water flow rate – say 20 gallons per minute – but if it the water will only run at that rate for five minutes before you run out, the well has a very poor water quantity (5 minutes x 20 gpm = 100 gallons of water) and it’s not a satisfactory well.

How many gallons per minute does a 1 HP well pump?

Number of submersible well pump stages determine pump lift capacity

How far can a 2 HP pump push water?

What is this? At the end of the day, though, the question turns back to push and lift. You can expect a 1/2 HP submersible pump to raise your water up to 10 feet out of the ground.

Is 1 gpm good for a well?

Many Mid-Atlantic states consider a well adequate if it produces 1 gallon per minute when complete, and consistently over specific time periods. The fact is that a 1 gallon per minute well will produce 1,440 gallons per day.
