I use a hose to fill all my tanks, I add the conditioner as the water is filling, never had a problem. The temp of the water here is fine out of the outside faucet in the summer, but winter the water is too cold, so I hooked it up to the faucets for the washer machine, I have the hot and cold hoses runing into a spliter so they both come out of a single hose, this alowes me to set the temp where i want it.
