My opinion - after you get that installed (for $1200-2000+ per prices noted in plumbing and review blog comments on the web) if ya got any money left I got a bridge in Brooklyn I want to sell you cheap. Or a nice illuminated steel tower in Paris built by some guy named Eiffel, if you prefer.

This type of item (under a lot of different brand names) has been pushed recently (and every 10 years or so) by some wholesalers and distributors, who convince plumbers to recommend and sell them (at a considerable profit). In some cases the local distributors and plumbers might actually believe the hype - in others it is just a way to bring in mega bucks with a gizmo that you can sell as the "latest and greatest" technology - despite the lack of professionally tested and reviewed scientific evidence that it does anything at all. There are several articles on the web from universities and even the Department of Defense (see source for one) who have tested this sort of thing and found it totally ineffectual, or in some cases with the powered ones actually promoting corrosion in the pipes near where it is attached. I remember one city water treatment plant I was sent out to investigate problems at - found they had a number of these type gizmos on the main piping (each at hundreds of watts power) and they were eating away the pipe and pumps and valves with electrolysis, to the tune of a couple million $ damage.

Are you familiar with the term "junk science" ? Like the clamp-on magnetic devices people sell to put on your car gas line claiming to increase your gas mileage by 50% with a magical electronic field - sound familiar ?

If this sort of thing really worked, industrial and water treatment operations and ships and large buildings all over the world would be using it en masse to eliminate pipe scaling - but they are not because they do not. The Lorenz field theory is used in very localized instances commercially to stop scaling - but it only works where the electromagnetic field actually exists around the pipe - it does not keep the minerals "charged" or "clumped" for any distance past the field application point, so can be useful in stopping or slowing buildups pumps and meters and such for a couple of feet of run, not for piping systems in general.

Oh - BTW - those units themselves wholesale for about $100-150 from a few checks I made, and are available at Home Depot for $125-175 depending on model - so a $1000-2000 charge from a plumber to just clamp it to a water pipe and plug it in should tell you something about what sort of product it is. Sort of reminds me of $5,000-10,000+ tankless water heaters .....

Google this search phrase for more on this type product - flow tech scam . Or even check Wikipedia under this category if you believe Wikipedia - electronic pipe scaling prevention

My recommendation - run, don't walk away from that kind of "miracle" device and any plumber who would recommend it. If you have bad water go with conventional carbon filter or disposable element cartridge filters plus carbon filter technology for odor/taste/oil problems only, salt based water softeners for hard water, or for really rank water a housewide water softener PLUS a dedicated kitchen drinking/cooking water carbon filter or osmotic treatment.

Do bear in mind, with older pipes that are scaled up - put in soft water and it will start leaching away the buildup in many cases, and in such situations the scaling is sometimes concealing pinhole leaks in the pipe underneath - so put in soft water with bad pipes and you can start getting pipe failures in quantity a year or few down the road.

The person that answered above has absolutley no idea of what he is saying ......these products work based on the principle of FARADAYS LAW. Ther are plenty of products that work this way and consumers should only beware that a trusted company selling these units has credibility and CREDIBLE LABORATORYS have tested same. One great way to know is to install a unit with this technology, use Cascade Complete so there is no soap residue and Rinse Aid in dishwasher . There should be no hard water residue and glass sparkles!

The water softner industry hates this technology because it undermines the sale of $7,000systems , massive profits and leaves consumers buying bags of salt for the rest of their lives.

Sounds like we know what sort of company the other commenter MarkMichel works for - all I can say is that that sort of system would not be on the scam lists at BBB and several government agencies if it was not a popular and common scam.

And the comments on Faraday's Law - that law describes the interaction of electric and magnetic fields and how inductive power is generated in a magnetic field - it says absolutely nothing about aggregating or "suspending" minerals to make them inert or non-objectionable, which is what this type of system commonly claims. Such suspension or ionization, even if it did what is promised, goes away very shortly after the water passes out of the electric field at the device - so even if it worked locally (which some very expensive large commercial units used in refineries and such do for short runs of pipe in aggressive chemical environments), it just is not going to provide protection through a household plumbing system. When used in industrial applications, the device - the electromagnatic field - normally surrounds the entire section of pipe being protected, at very significant capital and energy cost - certainly not what the advertised home units do.

And the normal water softener system is more on the order, for a normal size house, of $500-3500 depending on what specific treatment method you use and whether it has manual or automatic regeneration - commonly in the $1000-1500 range, not the $7000 he quoted. Here is an AL article on the subject FYI -

My advice - stay with the tried and proven and avoid the snake-oil salesmen.
