sounds like there isn't a shut off or it is not working.all your water is going down the drain!
screwing up the backwash by flushing the potty at 3am
forgetting to add Cl2 to the stripper filter,stinky water,
dead plants

All these kind of headaches were solved by putting a 1500gal storage tank and have city water trucked in twice monthly, cost tank$400,pump and pressure tank$500
water $100 monthly
we got it initially for the plants but use it for the whole house now, no more headaches
