Maker's recommendations on checking precharge ?

[Reach4]

How often should the precharge on a pressure tank be checked? Some people recommend as often as every two months. As far as I can tell some makers don't seem to require/recommend periodic checking. Certainly many homeowners never check the precharge after the installation. Here are some things I found and did not find, looking for data from manufacturers.

says "NOTE: The tank pressure needs to be checked AT LEAST twice a year. It is better to check it every-other-month. "

Pentair Southern Cross documentation says "... and then checked approximately every six months."

This Amtrol instruction manual does not specify to do check the precharge periodically.

I don't find similar Flexcon documents. They may keep their installation instructions hidden a bit, or I might not be up to the search.

It may be those makers who specify checking periodically don't hold air as well. Maybe the marketeers keep those instructions/suggestions out of easy-to-find documents. Maybe the technology is such that some tanks don't need air to be added during the warranty period.

Thoughts?

The good tanks will not lose air. The cheap ones can't be checked often enough. I check mine by run time on the pump. I have a Well Mate WM6 buried in my yard. I have to add air about once per year. I have a Cycle Sensor set up that looks at the run time of the pump. I set the Cycle Sensor to look for 60 seconds of run time. The first time the Cycle Sensor shuts the pump off and says Rapid Cycle, I know the pump is not running 60 seconds as it should and I go out and add air to the tank.

I have another systems with a Well-X-Trol tank WX203, that has not had any air added since it was installed in 1982.

Every tank company looses it's air these days because of the quality drop to compete against the clone tank companies over the years. Believe me, I have tried probably every top brand out there and none of them hold up like an old wellXtrol, (60's - 80's models) even our continuing education classes they recommend that we show the customer how to check the Precharge in their tank.

Warranty tank WM-6 quick connect.

These are my favorite tanks, that should last forever by just maintaining the Precharge yourself or you can spend the extra money on the micronizer.

People started noticing smell problems when they got away from using hydropneumatic tanks.

They had your best pump system figured out along time ago but they last to long now. Same thing happened with cars, appliances...
