Love this forum, as it has kept me away from the pool store! Had a broken light though, so needed them to fix it, and while here they "opened" my pool without me asking. Unsuccessfully. Filter had a bad air release, so they put it on recirculate and left me a note... Not even a phone call, but don't get me started... (I've left four messages over the past month and still no call back and the new light trips the breaker too!) plus we have a leak that we can't find and were down 6000 gallons over the winter. I had water delivered anyways... Gotta get this started, and it looks slow.
Point question: I replaced the air release and my filter is running, but I have no flow from the skimmer, and I need to backwash and add DE. I've never touched the valve you see here: could this be a diverter for my main drain vs. skimmer? I don't recall it's position from last year. Have not tried anything with it, as I thought I'd check here first.
