Location is northern Virginia ... Lingering question is whether I need to or should fully drain the large spa that shares plumbing with the pool ... It is proud of pool by about two feet of water level and is about three feet down into the ground. All gunite and stone.
Do I need to fully drain the spa? I have done so for about five years and it seems like it is both unnecessary and potentially damaging to the plaster ...
Would appreciate some ideas re best course of action.
