How do you pressure a water tank?

To pressure a water tank, you must first completely drain it and then apply air pressure using an air compressor. This process involves using the snifter valve.

Here's a detailed breakdown of the process:

Steps to Pressurize a Water Tank

1. Drain the Tank:

   • Open a hose spigot or sample tap connected to the tank. This allows the water to drain out.
   • Reference: Open a hose spigot or the sample tap to drain the tank.

2. Evacuate Remaining Water:

   • Use an air compressor to apply a small amount of pressure through the snifter valve. This step helps remove any remaining water from the tank.
   • Reference: Apply a small amount of psi with an air compressor to the snifter valve to completely evacuate the pressure tank of all water.

3. Close Drain:

   • After confirming the tank is empty, close the hose spigot or sample tap.

4. Pressurize with Air:

   • Add the proper amount of air into the tank using the air compressor through the snifter valve. The specific amount of air will depend on the tank's specifications and your plumbing system requirements.
   • Reference: Turn off the hose spigot/sample tap and add the proper amount of air into the tank.

5. Re-pressurization:

   • Your system has now been re-pressurized.

Key Points

• Snifter Valve: This is the crucial point where air is added to the tank using an air compressor.
• Air Compressor: An air compressor is necessary to supply the pressure. The exact pressure required is determined by the size and type of your tank, so always consult the tank's manufacturer instructions.
• Proper Pressure: Maintaining the correct pressure in your water tank is crucial for efficient water distribution and system performance.
