Hello all. Re-posting this from about a week ago with an update on a solution I've thought of and hoping for input on that. Solution (hopefully) is at the bottom in bold. Here it is:
After about an hour of searching, I couldn't find anything similar to my problem so please help. This is the first summer for my pool, and the salt level in the water was originally set at 3000 PPM by my pool service to work in conjunction with the Hayward SWCG last September. Everything was ok until recently. One of the several problems that's come up is that my salt level is up to 4300. And since I'm sure the salt fairy hasn't been visiting my yard, I've come to conclude the Water Softener is causing the sodium level to go up since it is connected to the autofill. So before I drain and replace, I want to know suggestions on how to get around this. My builder told me that the autofill ran direct from the street, but when I checked recently, the main into the house goes right into the filter and softener units. He's out of the picture since I fired him for other issues, so his lie does not surprise me. The way I see it there are three ways to remedy this, and I'll list them in order of desirability:
1) Install some kind of low cost sodium filter at the autofill
2) Replace my salt based water softener with a low cost descaler (also called a conditioner)
3) Get this re-plumbed somehow to send the pre-softened water directly to the autofill.
A trip to Leslie's for testing of the water showed 600 PPM, and the gal there said there is no filter of this type, but the girl behind the counter looked about 11 and I would not trust her expertise. The descaling options which consist of wrapping wire around the pipe seem good, but there are a lot of naysayers saying science does not support manufacturers claims, and I don't want my house water to suffer just to correct the autofill. And a re-plumb seems like it could be pretty costly. It would require splitting the line and running pipe an additional approx 200 feet to meet the autofill. And I don't even know if that's legal.
Or could something funny be going on and the 600 PPM water not be enough to bring the 12,000 gallon pool up 1200 PPM in 10 months? Please help, and thanks in advance.
I have found my water softener, a Morton MSD30D, can also work with potassium chloride pellets. Do I have anything to worry about by having potassium instead of sodium going into the auto fill valve?
