Newbie here. I bought a house last year that had been sitting for about 2 years. The pool has a SWG, but the previous owners thought it was hit by lightning after they moved. Pentair customer service said I need to add 18 bags of salt (since none is left in the pool) to see if the SWG is operational. Lights come on, but it doesn't read anything. Since we bought the house late last summer, we didn't worry with the SWG and just did chlorine manually based on the pool company's recommendation. This year we want to be more hands on and do it ourselves. So, here are the questions I have:
1) Is there another way to troubleshoot without buying 18 bags of salt?
2) Is it worth the effort/money to have it replaced if it was indeed hit by lightning?
3) If I add the salt and decide to hold off on the new SWG (assuming this one is fried), will the salt cause any problems with the water without the SWG running?
Any help is greatly appreciated.
