 Topic: Replacing a well pressure tank
Posted: 30 Nov 2018 at 7:08pm |

Gonna replace my pressure tank tomorrow for the well system, my question is once I get all the plumbing done , should I fill the pressure tank with water before putting air pressure to it then drain , or just put air pressure to it , then fill?

Instructions usually come with the tank. If I remember right, for bladder tanks, you add air until the pressure is 5 lb. below turn on pressure. Then turn the pump on.

I believe they are already set at the correct pressure. You want the bladder tank to be set lower than the pump shut off switch is. I just put one in and the pressure in the bladder tank was preset at 37 psi and my switch on the pump is 40 psi.

YUP^^
Since different mfg's make different tanks, when all else fails, follow the instructions...

If all else fails OR you want to know for sure, PM Les or wait for him to come on here and see this thread. He told me explicitly (step by step) once and he knows his chit about this,,,,,,,,,,,,,

my tank came pre-pressurized years ago. I remember the well co kept checking the pressure and kept releasing air from it.
