What are the Usual Water Pump and Tank Pressure Control Settings in PSI?

Most residential water systems using a water pressure tank and water pump use one of these two pressure operating ranges:

Low-pressure operating range pumps like low horsepower pumps and many jet pumps

• Cut in (start pumping) – 20 psi
• Cut out (stop pumping) – 40 psi

Higher-pressure water pumps, like submersible pumps, and higher horsepower 2-line jet pumps

• Cut in (start pumping) – 30 psi
• Cut out (stop pumping) – 50 psi

How High Can we Set the Water Pressure in My Building?

You can’t just set the pump pressure as high as you want to. Here’s what can go wrong with excessive pump pressure control settings:

• Exceeding well pump pressure capability: If you set the cut out (stop pumping) pressure higher than the water pump is capable of reaching, the pump will just keep running indefinitely until it burns up or blows a fuse or trips a circuit breaker or overheats.
• Causing a ruptured water tank internal bladder: we have had a number of reports of ruptured bladders in water tanks. In normal use the bladder in most water tanks is not stressed at all – the internal water tank bladder simply moves up and down as water enters or leaves the tank – pressure on either side of the bladder (air on one side, water on the other side) remains the same.

  If your water tank were a less common model in which air were inside the bladder rather than outside it, excessive air pressure could burst the bladder. If you set the water pump pressure too high on one of these systems, you might cause the water bladder to rupture inside the tank. In an extreme case you might blow up the water tank itself. Most water tanks are not designed this way.

• Blowing up a water pressure tank – serious safety hazard: if you set water pressure too high, even if the pump is capable of reaching that pressure it may be unsafe. Most water pressure tanks are designed to operate safely in the water pressure ranges we cited above. If you had the bad luck (and stupidity) as to be using a water tank that has no pressure relief valve installed, it is possible to cause the tank to rupture or even explode, risking damage to the building or even serious injury or fatality if anyone is nearby.
• Causing leaks at fixtures: even if your water tank were rated for high pressure, and even if your water pump is capable of high water pressure, if you run water pressure in a building over 70 or 80 psi you can expect to have recurrent leaks at plumbing fixtures: most water faucets and tub faucets are not designed for high pressure use.
