Underground well-water pressure tank?

Question

I need to install plumbing in my Northern Michigan (cold!) hunting cabin, but want to keep the pressure tank outside and underground if possible. Does anybody make a tank that can simply be buried below the frost line to prevent it from freezing in the winter time? My idea is to bury a tank (if possible) and have it run to a drain-back outdoor hydrant. Then, when I want water inside the cabin during the summer months, I can hook a garden hose from the hydrant to the cabin plumbing, and pressurize the system by turning the hydrant on. When winter comes, I will simply unhook the garden hose and drain the cabin pipes. Idiot-proof way of preventing frozen pipes. And, I will still have accessible water, it will just be outside at the drain-back hydrant. My only roadblock to this "ingeniously-redneck" idea is that I can not find a underground pressure tank. Anybody know if there is such a thing? If so, are they durable enough that they don't need to be dug up and serviced every year?

In the rural north a large majority of pumps and tanks are installed in a wood or concrete lined hole in the ground with an insulated lid. You can service the unit by simply lifting the lid instead of having to "dig it up".

Answer 4

Have you considered using a regular tank placed in a pit deep enough to be frost proof. ? I doubt if you will find a tank which can be completely buried

Answer 5

Is your septic system a "mound system?" Your description sounds more like that...and if so, I wouldn't do any digging.
