They do have water softeners you can install between your water supply hose and buffer tank/equipment if it’s something that bothers you that bad. If hard water is really bad and, really well known in your area, maybe you can use it as a marketing strategy. I haven’t heard of anyone on the forum using a water softener though. I think most hot water units have them but are mainly to help prevent minerals from forming in the coils. The spots should be an easy up sell to customers who are also bothered by them so I don’t know if I would go the water softener route unless you can somehow benefit from it.
What are you using in your house wash mix?
This is the backpack sprayer thread I was thinking of. It has some good tips from Corey too.
