Not really the basement, but the external entryway (not used) to the

tunneling experiments.

I suppose two valves would be best, as it would let me service the inside
valve without draining the pond. But there would still be no easy way to
get
at the outside valve for servicing.

Here, we'd just plug the bottom drain & skimmer with a plug to fix valves.
So inside, where you don't have to dig, if you can keep it freeze free...
which, if a small insulated space, depending on pump type/size, may keep
it
warm enough.. if you run it during the winter, even a small heater set on
low would due.

I've been toying with the idea of putting a heater inside the filter and
diverting the return flow below the surface, but I suspect I would have too
much heat loss.

I know when I was growing up we had several acres for our horses and a
small pump house, about the size of an elevator room. Irrigating started
early in the season, often causing ice on cold mornings to form. While the
pump was running, the pump house was the place to go to warm up after
moving hand lines. ~ jan

LOL, we had a pond too, but with beavers not horses. :-)
