Hello everyone,
Attached is a sketch showing the water supply from the cistern to an outdoor faucet mounted on the house wall. My question is whether anyone has an idea on how to make the entire system frost-proof.
Problem 1: The first problem is that the water pipe, shortly before reaching the house wall, leaves the frost-safe burial depth and could potentially freeze.
Problem 2: The second problem is how to make the water outlet on the house wall frost-proof.
My idea: A frost-proof faucet that is not connected from the inside of the house wall but instead sits only about 15cm (6 inches) or 20cm (8 inches) deep inside the wall. I would protect the water line in the non-frost-safe section with a heating cable.
Does anyone have any ideas or has faced a similar problem? Are there any control systems available?
Thanks in advance.

The pump is floating inside the cistern. The picture shows the current situation. It was built this way.

Bieber081517 Jul 2017 11:55In my opinion, you are only truly safe if the pipe is empty during winter. There must be an access point to the cistern for maintenance or inspection, right? The pipe should be drainable up to that point.
Have someone explain exactly which type of backflow preventer is being used. Valves commonly used for cistern applications often allow water to drain slowly.
By the way, I have never heard of or seen a floating pump. I only know of submersible pumps that rest on the bottom of the cistern, and suction pumps that are installed above ground and draw water up. Only the latter require a check valve to keep the suction line filled with water (this eliminates the need to prime the pump and allows water to be drawn immediately after opening the tap).
Both systems allow for a "floating draw-off."

You could also deactivate the pipe that is permanently connected to the house and install a separate water outlet independent of the building. This should also be drained in winter, but the potential damage would be much smaller.

Have you considered frost protection, just like with a car radiator?
