How to replace a water filter tank

How to replace a water filter tank? First you would turn off your water. And then you would open a faucet somewhere to relieve pressure. At this point if you have a bypass valve, you would bypass the unit. And then the next step would be to unhook the unit from the pipes. Also, you want to unhook the drain line and the power cord.

At this point you simply unscrew the control valve on top of the tank counterclockwise. And as it becomes loose, be careful that you take it off gently. When replacing the tank, it is always a good idea to replace the minerals inside as well. We can provide you new minerals in any amount. If you measure the filter tank, we will know exactly how much media (Mineral) you need.

And most water filters have a gravel bedding in the bottom of the tank to keep the riser tube stable. If you are not sure if you need a gravel bedding. Just empty your current tank and see if there's gravel in the bottom when you pour it out. If there is no gravel, and the riser tube inside of the tank appears to be attached to the bottom of the tank. Then no gravel is needed. Just remember that gravel is OK to place in the bottom of any tank. It will never hurt. It will only help.


Remember that if you replace your current water filter tank with a tank that is TALLER. You must replace the riser tube inside as well. We have water filter riser tubes as well. So don't worry.

If you do not change the height of the tank. Then your current riser tube should work. But if the water filter tank is old. It is best to replace the riser tube anyway. If you need assistance.
