    Phoenix/Tucson how long before drain/refill because of excess calcium hardness?

    I am wondering for Phx/Tucson area folks (or anyone else with high calcium in your tap water) How long before your Calcium levels are so high you need a partial/complete drain refill?

    Depends on how high your CH starts at. Mine for a fresh fill is about 130ppm and it goes up about 125ppm every year. So after 4 years or so, the CH is getting to the point that a refill would be helpful in preventing scale.

    Are you metro water? I haven't tested it yet, but all the builders I've talked to says you'll be draining and refilling every 5 years because of CH.

    Semi private well, so my water is better than most.
    If your water starts harder, then I think you will want to replace water much less than 5 years. Harvesting the little rain we get can help too.

    My water is currently at 800ppm CH and I'm able to manage it just fine. Using a pool cover and keeping evaporation to a minimum is key in high water hardness areas. Rain harvesting is a great idea if you have adequate roof area and good area to put a storage drum.

    It seems like the average varies, but generally falls into the 3-5 year range. I'm going into my fourth year with the same water. I don't know if I'll make five years, we will see.

    I know Richard320 just runs it off the roof straight into the pool. Drain a little before the expected rain.

    I have not tried this, although it would actually be pretty easy for me to setup.

    My CH is up to 500ppm, after 3 years starting with a refill of 130ppm. Was thinking of replacing it next spring. Of course I have the advantage on the well, that a refill costs me only $15 for the water. Although then have to add $60 for CYA and $60 for salt. So, under $150 to start fresh.
    Still have a box of borates that I did not put in last year because I knew I would drain fairly soon, so figured I would wait.

    Cover is too much of a hassle
