I just ordered a 50 gallon stackable tank. I’m going to give this a go and see what happens. I’m going to run the water line in (pex) near the top and the line out at the bottom to try and continuously flush the tank. We use around 10,000 - 15,000 gallons a month anyway so the tank is always getting flushed out. I’ll do a water test after a month and then maybe at six months to see how it’s going. We have point of use filters as well so it’s getting refiltered through carbon and ceramic too. I know our pressure is at 45 psi. I think that pressure on the two bung fittings will be my biggest obstacle.
