I have looked into that but didn’t buy the system since it would make the water even harder so a water softener would need to be added. I didn’t want a basement full of water treatment to maintain. I have a simple DI system for the final rinse when washing cars. I use distilled water in the coolant systems in my shop and all vehicles. The price of distilled water did go up to over a dollar most places and Walmart has it for about $1.22 nationwide, so there is no reason to use anything else, unless a person is cheap beyond comprehension.
I dont want to stray too far off topic here but I want to clear a few things up that may be beneficial to you or other members that read this.
First off I don't work for Culligan, and at least in my area they are one of the biggest contributors of customers to our small bussiness becuase they (culligan) put on a dog and pony show and end up trying to sell .customers very expensive proprietary systems that some customers don't even need.
In the case of modern ph balancers for rasing ph there are literally no moving parts to maintain. It is a softner sized tank filled part way with a calcite and magox mix that the water flows through and as the water flows it dissolves the compounds at a very slow rate and raises the ph. These in most cases require a 1x a year check and top off some customers get away with 2-3 years depending on exact ph and water usage. There is literally no maintenance for the customer. Also just becuase a customer adds a ph balancer does not nessacarily mean there hardness will go up. We have tons of the balancers in place that have no other system. That hardness raised by ph balancer sounds like a "Culligan myth."
Now yes if you already have borderline hard water or naturally hard water a softner would likely need to be added to get the full benefits. But the ph balancer will not raise the levels enough in and of itself in 99.9 percent of cases.
Softners are also virtually no customer maintence add salt set the time of day that's it and they only use salt every x amount of gallons if properly installed with a water meter.
Our softners cost roughly 1700 installed out the door all parts and labour. And the ph balancer cost significantly less (I would have to look up the exact amount) to install since it has nopowerhead and thus no moving parts.
Even if both of these where installed by a proper water treatment company it would likely cost less then replacing every fixture pipe and fitting in a house and still not fixing the actual issue. They would solve the problem at its root (or at least close when the h2o enters the house) and eliminate the worry of having burst pipes, clogged fixtures messed up water heaters boilers dishwashers washing machines etc.
I know I strayed way off topic here but I think it's important for others to have all the facts from someone who works with this stuff every day and is employed by a small family company who has been around for over 30 years with no advertising (this doesn't count lol). At the end of the day I'm not a salesman I'm a tech I have no dog in the show, and I don't get paid on commission so I pride myself in honesty.
