We just had our inground pool completed about 4 weeks ago. The pool
is open so that we can brush the plaster as it cures. The PCC 2000
filter system runs 24x7. We have another 2 weeks (minimum) of
brushing recommended by our pool company. We live in Northern
Virginia where the temperature has been 50 - 60 during the day (now in
Dec) and 30's at night. The folks at our pool servicing company said
we may want to leave the pool open through the winter instead of
closing it up and reopening in 3/4 months. They said as long as there
is no deep freeze and the filter stays on continously we shouldn't
have a problem. My question is what defines a deep freeze? And is
this really safe on something I just spent a lot of money on?

When I bought our last house with pool, the previous owner kept the
pumps running
24/7. I did too for the first 3-4 years until we had weather down in
the teens, which was still fine until the power went out. Now I had to
deal with broken pipes and a cracked heater mainfold. After that I
always close the pool for winter. It's time well spent to not have to
worry about it, not to mention the waste of electricty.
