We ski-leased a place with electric shutoff. The real estate agent detested the system. If we were leaving, and power was out, the agent had to crawl under the house to drain the pipes since there’d be no heat… or hope power would return before freeze set in.
So, when we bought, we opted to have mechanical shut off and drain valves extended into the living space so we didn’t have to crawl under the house or deal with what-if-there’s-a-power-failure.
We were quoted three options — vertical risers into the house from current shutoff valves (into Living room), relocating valves to middle of house and putting levers in sink cabinet so not visible, or external valves on the side of the house accessed from the deck.
You might ask a couple plumbers to suggest solutions for you.
