Scrapping out a full brine tank

[nova_robotics]

I have to say it hurt me to see a perfectly good, heavy duty, plastic barrel cut up and tossed away like that.

I'm a massive pack rat, bordering on hoarder. I see fibreglass pressure tanks on the side of the road all the time. I've always resisted the urge to throw them in the back of my truck. I keep thinking that the diaphragm is leaking and the tank is probably still good. Not sure what I'd use them for. It just seems like a waste. In your experience is it just a diaphragm failure?

Edit: Come to think of it, I rarely see steel pressure tanks out for garbage day. That can't be a good sign.
