You can buy test strips to check if the water is softened or not. I use them to adjust as well.Figman2 wrote: ↑ How long does a softener usually last?
Mine is about 15 years now but I don't if it is still working good or not.
Lately I find the water pressure is low but not sure if the softener is causing this. Right after a toilet flush, the faucet has very low pressure until the toilet tank is filled.
If you have a bypass valve then use that to see if it improves your pressure.
