Testing your Water Softener quarterly????
We check ours daily as part of a daily checklist. Only takes 2 minutes.
A couple of days of running hard water through your RO machine, and your checkbook will tell you why quarterly isn't enough. Hard water plugs membranes.
Although quarterly may be the minimum I would think daily is excessive on the other hand. I dont anticipate my water softener to completely fail overnight. A water softener may become less effective over time and the hardness of the water should be monitored but I use other indicators as well to make sure my softener continues to function properly such as:
1-putting a flashlight up to resin tank and marking the level of the resin in the tank
2-monitoring salt levels to be sure its consistently being depleted
3-taking note of when regeneration cycles are taking place and comparing that to salt levels as well
These are a few of the things I look at but it seems you are much more attentive to your water quality so what else should I be doing to keep up with mine?
