My spa (slightly elevated from pool, overflow into pool) is draining into the pool when the pump stops running. I was told something about a valve...can anyone explain how this works (or in my case, doesn't work)?
You have a bad check valve or one of the diverter valves isn't closing completely. Try using the search box. You'll get a bazillion hits, so try to narrow the search to thread topics or first post only.
