I was hoping that someone could help me- I have the clack WS1 valve and have had so much trouble with my water softener. Twice in the last year and a half the plastic tubing from my brine tank to the mineral tank has cracked or broken off. I replaced it and it worked fine for one month. now the water is hard again. I regenerated yesterday and the water is hard once again. The salt level does go down but the water is hard. the guy who installed it has been a problem since the beginning. when he first installed my tank he forgot to put the salt in it. then when he did there was always some type of residue on my hands after washing them. he finally replaced the mineral tank and the tubing keeps cracking or breaking.
He said he would charge me to come out and I do not want to give him another dime since I have had so many problems.

can someone please recommend what I should do to troubleshoot this?

thank you so much!
