FAQ's


 
What is the maximum working pressure of a Flexcon tank?

Models PC44-PC366 and WR45-WR360 have a maximum working pressure of 125 psi.

Models WWT14-WWT120 and H2P15-H2P120 have a maximum working pressure of 125 psi. 

Models FL5-FL40 and H2PL15-H2PL120 have a maximum working pressure of 125 psi.

Models CSS15-CSS120 have a maximum working pressure of 150 psi.

Models FLU30-FLU120 and FLS40D-FLS120D have a maximum working pressure of 100 psi.

Models H2PLU30-H2PLU120 and H2PLS40D-H2PLS120D have a maximum working pressure of 100 psi. 

 

What is the maximum working temperature of Flexcon tanks?

200° Farenheit/ 93.3°  Celsius for steel tanks.

120° Farenheit/ 34.7°  Celsius for composite tanks.

 

Can I use glycol (anti-freeze) in a Flexcon tank?

We recommend not using over a 50/50 mix. Under no circumstances can the product contain a petroleum base. We recommend using Propylene glycol.

 

Can I use petroleum base products in my Flexcon tank?

No. The material in our diaphragm will not tolerate petroleum products.

 

Can I install my Flexcon tank on its side? 

Side installations are acceptable up to the WR140 and PC144 sizes. In fiberglass tanks the FL17 or H2PL50. The underground tanks manufactured by Flexcon are designed for horizontal installation and are availabe lin three sizes up to WR140BGR. We do not recommend horizontal installations for any tanks larger than WR140,PC144, WWT45, H2P45, FL17 or H2PL50.

 

What is the warranty on Flexcon tanks?

All Flexcon well tanks carry a 5-year limited warranty from the date of the manufacture on the original tank. Some thermal expansion tanks have a one-year limited warranty. 

 

Does the warranty cover labor?

No, unfortunately there are a number of factors that can contribute to a failed tank and the only factor that Flexcon can insure is the tank. 

 

My tank was just installed and the water has a funny taste. What should I do? 

Flush the new tank by allowing water to flow through three or four pump cycles. If the taste continues, you should probably have the source water tested.

 

Can I use chlorinated water with my Flexcon tank?

Of course. Flexcon tanks are designed with the knowledge that chlorine is often used to periodically treat a well. 

 

What is a cycle?

A cycle refers to the pump run time. A cycle starts when the pump starts and a cycle is completed when the pump stops. Pump starts and stops are determined by the pressure settings of the system. Below, we demonstrate a tank's drawdown feature that assumes a water system with a 30/50-psi pressure setting. This means that the pump will start ("cut-in") whenever the pressure reaches 50 psi. Common pressure settings are 20/40, 30/50, and 40/60.

 

How does a pressure switch control the pump and tank?

The pressure switch communicates with  the tank and activates and de-activates the pump when the cut-in and cut-out pressures are reached inside the tank.

 

What is drawdown?

Drawdown refers to the amount of water that evacuates the tank before the pressure switch will activate the pump. Drawdown is affected by the pump, the size of the tank, and the pressure settings that govern your water system.

 

How much pressure (pre-charge) should be in my tank?

Your tanks should be pressurized to 2 psi less than the cut-in pressure setting. For example, if your pressue settings are 30/50, then your cut-in pressure setting is 30 psi and your tank should have a 28 psi pre-charge. For constant pressure systems, the Flow Thru tank pressure should be 70% of the set point on the drive.

 

How do I check or change my pre-charge?

You must completely drain the tank to check pre-charge. To do this, shut the power off to the pump and open (turn-on) a faucet in the house. This will drain the tank and not allow it to refill. On top of the tank you will find an air valve (similar to the air valve on your tires)- use a tire pressure gauge to check the air pressure.
