We've recently moved from Seattle to Las Vegas (talk about a welcome change of weather, gloomiest city in the US to probably the sunniest!) and our new house came with an inground pool:
Here's some shots of the filter/pump setup:
Everything turns on and operates without blowing up or bursting into flames, which I assume is a good thing. The valve was originally set to the "Backwash" setting.
I read up on pool equipment maintenance and found that I should change the valve over to the "Filter" setting, which I did, only to find that running the pump on that setting actually drains my pool. I don't know where the water goes.
Where should I start with this problem, if it indeed is a problem? Let me know if I need to provide any further information!
