Cathodic Protection of Underground Tank

Whimsey · 03-24-2021, 01:17 PM

I own my 1000 gal underground propane tank (Eastern provides the propane and I get an extra 10 cent/gal off the Our Town coop rate). I know taks can last 30-40 year if properly maintained. How frequently do i need to refresh the cathodic protection anodes?

You should be testing every 3 years minimum and replacing them as needed. Course many companies never test them.

Interesting. So if your propane supplier owns the tank I assume they should be performing this testing?

When I built I considered an underground tank with Eastern. Though the tank would be theirs the maintenance on it and the fittings were not. Those cost would be mine. Decided against it.
