Hello. Thanks to everyone for their help in this forum.
I put in too much salt and have to do a 1/2 drain and refill.
I have a Letro autofill feature.
For the drain I have shut off the valve at the outdoor faucet - tightly.
I noticed that the refill hole for the water is leaking a little. The last time I did a drain/refill I don't think I saw that. I removed the Letro autofill and re-plumber taped it and rescrewed it in. And I'm still seeing that water leak out the hole area. Looking at the Letro, I see that it looks like the water is staying within the letro tube but the water is leaking out of the tube a little ways up from the bottom. I have attached a photo to show it.
Is this normal?
