Pressure tanks

[VancouverIslander]

For what it's worth, I've just used a box store cheap tank and been fine so far. The tank that came with our place was also that variety and lasted probably 8 years or so of abuse - pump and tank were left out in the weather for about 6 of those years and then the pressure tank failed putting additional strain on the pump so we replaced both to be safe. Hoping for another 5-10 years before the next replacement.

Me ka ha`aha`a,
