Product Code: ROT-4
  • Aquasky ROT-4 Reverse Osmosis Tank:
  • The Aquasky ROT-4 RO Tank has a durable steel shell with a free-standing plastic base.
  • Reverse Osmosis Tank Specs:
  • Dimensions (Approximate): 11" W x 14" L with stand
  • Tank Volume: 4.5 Gallons
  • Water Capacity: 3.2 Gallons
  • Reverse Osmosis System Accessories:
  • Use a TPG-100 Digital Tank Pressure Gauge to measure the air pressure in your Reverse Osmosis Bladder Tank. The RO Bladder Tank can lose air pressure and needs to be monitored.
  • Use an Inline TDS Meter to monitor the Total Dissolved Solid levels before and after your Reverse Osmosis System.
  • Instructions to Properly Pressurize your Reverse Osmosis Tank:
  • Before setting the pressure on your tank, you should empty the tank of water.
  • 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.
  • You should use a digital pressure gauge on the nipple because non-digital pressure gauges are not sensitive enough. You can purchase a digital pressure gauge here if you do not already have one
  • Correct pressure for your Tank:
  • The recommended pressure for your tank depends on the size of your tank. The most common tank size is 3.2 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.
  • For larger tanks, such as 14 gallon, 36 gallon, 44 gallon, and 86 gallon units, the pressure will need to be greater.
