CHECK TANK PRESSURE

WHEN: 

Yearly

TOOLS:

Piece of 3/8” tubing OR Bucket

Bicycle or tire pressure gauge

Bicycle tire pump

1.  Drain water from the storage tank.

a.  Shut off the inlet water supply by removing the pre-filter or water booster system if 

applicable.

b.  Make sure the tank shut-off valve located at the top of the water tank is open.

3.  Using a standard bicycle or automobile tire pressure gauge that is capable of reading 

pressure accurately from 0-10 psi. Connect the air pressure gauge to the Schrader Air 

Valve on the water tank.

4.  Read the tank’s air pressure.

5.  The air pressure should be between 8 and 10 psi.

6.  If the air pressure is below 8 psi or above 10 psi complete the following steps.

a.  Using a standard bicycle pump add or release air pressure in the tank.

b.  Repeat Steps 4-5 until the pressure is 8-10 psi.

c.  Make sure the blue cap is replaced on the air pressure port.

7.  Close the water sample valve.
