Hi, first post here. I've been lurking for a while. I'm new to pool ownership, having just bought a house with the pool listed below in my sig. I've been digesting all the info here and I think I've got a pretty good handle on the water chemistry thing....except for my calcium hardness. I did several tests and it's showing in the mid-800 range. Our water is pretty hard to begin with (tap is about 250) but it seems I need to drain and refill. According to the pool calculator I need to drain about 70 percent of the water.
I'm trying to figure out if my pool's plumbing has a connection to the sewer in order to drain it. There are a whole mess of valves and shutoffs back there, but none of them are labeled so I don't know what I've got going on. Is there something I should look for in the plumbing that would indicate if there's a connection to the sewer from the pool plumbing? If not I guess I'll have to drain it manually with a sump pump, but that seems like a bit of a pain.
I can post pics of my plumbing setup if that would help.
