replying in banter as to not derail the long range thread.
its pretty bad, I think you would notice if it was impacting your well. We've been in our house for almost 11 years now. We have replaced our well pump/tank, water heater, faucets, etc. many times in those 11 years. the sodium chloride they use in road salt is corrosive, eats away at pipes and tanks like crazy. we actually sued the state and won and walked away with a small settlement that would pay for an RO system in the house. But then covid happened, and we kept the money in savings in case shit hit the fan. Our water still sucks and I hope one day we can put the RO system in the house. But its going to a pain, a new well field will need to be dug, a big trench off the house out to the new well field, etc. So much work to do to have good water.
So we have water delivered to the house to eat/cook with, and we have a great plumber on call when our well pump/tank and water heater fail. Yippee.
