Request Solution For Mineral Deposits Build Up

[SoakMaster]

Our 325 gallon spa is 14 years old. The master valve/jet -- the one we turn inside the spa (under the water line) to direct which set of jets operate -- has been frozen in place for a couple of years. I suspect calcium or other mineral deposits have locked it up. Short of replacing the valve, is there a proven method that provides some kind of chemical cleaning of buildups of mineral deposits?

I know soaking shower heads in white vinegar removes deposits; is there something comparable for old spas?

We replaced the pump and heater pack (replacement was unrelated to the suspected mineral buildup), so the spa otherwise runs great. We'd just like to be able to return to dialing the different jet settings.

Thanks for you consideration/comments.

PS: FYI, I attempted to email my query to [email protected]; that address bounced. I don't know if the bounce is an interest of yours or not, but sharing that here if it helps.

you can try swirl away plumbing cleaner, as it is in the tub, keep trying to turn the knob a little, dont force it though. You will have to keep it in a longer time than stated on the bottle. It maybe easier and cheaper to replace the entire diverter valve. Many people leave jets and valves in one place, and no matter how great the water chemistry is they become stuck over years. I always tell people to turn their jets, diverters, air controls etc. on/off a few times at least once a month to keep them free.
