The Flex-Lite FL series' improved CAD2 diaphragm design is stronger and won't crease and wear out like bag designs. Flex-Lite well tanks features a chlorine resistant 100% butyl diaphragm with a precision molded copolymer polypropylene lower water chamber for superior air and water separation. This patented design allows each size tank to have a properly sized water chamber, matched to the drawdown performance of that tank. When it comes to performance and durability, the CAD2 system cannot be beat.

Flexlite FL7 pressure tank

Our 10 year old pressure tank failed so I searched locally and online for a replacement. Found this website that had a better price than I could find elsewhere as well as free shipping. Called to confirm authenticity of the company, placed my order and it arrived about a week later. Packaged very well from the manufacturer, was undamaged and great quality. Easy install as it was a direct replacement. Set the pressure before I introduced water at the recommended 2psi below pump kick on pressure and put it in service. Only had it installed for a day, but it looks to work as expected.

Q: what should the air press. be set at for my FL 7 22gal. tank. the water limit switch is set at a max. of 60psi.

Asked by: george sitek - 9/23/2020

A: The air pressure when the pressure tank is empty should be 2 pounds less than the pressure that the switch turns on at. For example, a 40 to 60 PSI pressure switch would have an air charge of 38 PSI in the pressure tank when it is empty. It is important to have your tank empty of water when making adjustments as a full tank will not read correctly for it's pre-charge air pressure. Your switch is cutting off at 60 and there is usually about a 20 PSI difference between kick on and kick off pressures.
Set the air pressure to 38 PSI.

Q: Does the fl7 require air to be put into tank from time to time. If so how often and what psi.Cut in pressure set at 40 psi cut off pressure set at 60 psi. Thank you

Asked by: Frank - 9/9/2023

A: Air should be entered into the FL7 pressure tank only when the tank is empty of water. Do not add air when the tank is full of water. The pre-charge pressure of air should be 2 PSI less than the kick on air pressure set on the pressure switch. For 40 PSI on the kick on setting, this would be 38 for the air setting. If air is required to add at an ongoing basis, the internal bladder most likely has a leak and the tank will need to be replaced.

Q: We recently purchased Flexcon FlexLite Fl7 22 gallons pressurized tank. After one week of use, we cannot use two water fixtures together ( toilet and vanity or washing machine and toilet at the same time) The tank looses all its pressure and I need to reset the tank. We have a very little cottage with not many water fixtures. There is lots of water in our well . Pressure is set at 38 psi. There was no problem with previous device but it was starting to rust. We like that this tank is fibreglass.

Asked by: Brian Ganim - 9/1/2022

A: The proper setting for the pre-charge of air in the FL7 Pressure Tank is 2PSI less than the kick on pressure. For example if the pump activates at 30PSI then the pre-charge air pressure would be 28PSI. It is important to note that air pressure should be set when the tank is completely empty of water. From new, the FL7 comes with a setting of 38PSI air charge. This will need to be adjusted to the value which is 2PSI less than the kick on pressure. If the air charge is not set correctly, your pump and pressure tank will not function correctly and could be the cause of the issue you are experiencing.

Q: How do you get outlet water from the tank. There is only an inlet fitting, no outlet

Asked by: Danny - 8/11/2021

A: Plumbing connections are required for the water inlet and outlet. This can be achieved via the dedicated Tank Fitting Package TFPB1F3U4060. Please consult a qualified installer if you are unsure.

Q: Is the air chamber is replacable , can we take it out to put a new one in it

Asked by: Jonathan Ten Have - 10/14/2019

A: The Water Chamber and remaining space (Air Chamber) are not replaceable. The tanks are completely sealed and there is no way to access the internal pieces. It is possible to add air through the valve at the top of the tank. The instructions to do so are in the Installation Manual which can be found in the Product Details.
