  1. Before setting the pressure on your tank, you should empty the tank of water
  2. There are two nipples on the tank. The nipple on the bottom should have a blue cap on it. Remove this cap and use a bicycle pump to add pressure to the tank
  3. You should use a digital pressure gauge on the nipple because non-digital pressure gauges are not sensitive enough
  4. The recommended pressure for your tank depends on the size of your tank. The most common tank size is 2 gallons. For these and similarly-sized tanks, you should have pressure of 8 psi when the tank is empty. If the tank is full, there should be 36 psi
  5. For larger tanks, such as 14 gallon, 36 gallon, 44 gallon, and 86 gallon units, the pressure will need to be greater
