Jim M: "After the installation of the Housetron the glass in my new shower looks just like it did the day it was installed.  There is absolutely no scale buildup at all. This shower has 3 times the amount of glass as the old one. We use no chemicals at all on it now...."

Jimmy and Karen E: "Since installing the housetron unit, our icemaker makes approximately one-third more ice and we haven’t had any repairs on it. Because of this and what we have noticed with our shower and dishwasher, we also feel confident that our other appliances and plumbing are benefitting as well...."

dave_chrissie.jpgDave and Chrissie L: " I installed a Housetron myself using fittings from Home Depot, we're very happy that our water no longer has the slimy feel that we had with our old water softener. I have a bad back so not having to buy and move salt bags is a big advantage to me."

Dayle and Kenneth G: "We couldn't be happier with this product. We are now several years in residence and are very satisfied with the results so far".

Scale build up in the home: 

  • Affects system pressure and reduces flow rates

  • Raises energy costs as scale insulates and reduces the efficiency of water heating appliances such as boilers, hot water tank heaters, tankless water heaters, coffee machines, kettles etc.

  • Leaves unsightly deposits around baths, showers, sinks and toilets particularly around shower heads and faucets. This often requires tiresome cleaning with de-scaling chemicals.

The problems associated with the use of conventional water softeners: 

  • Water softeners utilizing salt have a detrimental effect on the environment and drinking water quality

  • Initial cost, running costs, size, consumption (water / salt / power)

  • The overall inconvenience of maintainance and operation: carrying salt bags, dosing etc.

  • Interruptions in water supply during backwashing cycles

Benefits of using the Fluid Dynamics Housetron solution:

The Housetron prevents scale build up and hard water stains when installed on new systems and gradually removes scale from previously untreated older systems ( this process is gradual and it may take up to several months to de-scale a previously untreated system ) 

No detrimental effect on drinking water unlike salt utilizing conventional water softeners

As the Housetron replaces existing water softeners all the running costs and inconveniences associated with the use of conventional water softeners is eliminated. No more salt carrying, water waste and no more damage to the environment.

You can fit and forget the Housetron as the Fluid Dynamics solution is completely maintenance free requiring no chemicals, electricity or salt.

With no backwashing required a continual water supply is assured.

Compatible with any pipework material, the easy installation can be carried out either, by a DIY enthusiast or, a plumber. Installation involves replacing a small section of pipe with the Fluid Dynamics Housetron and typically takes under 30 minutes.

Installation and sizing:


This simple example shows a 3/4" Housetron about to be installed in a previously untreated galvanized steel system. 

The home owner installed the unit after noticing significant scale build up during the installation of a tankless water heater.

houseInlet.gifThe Housetron is an in - line treatment unit that can be mounted horizontally or vertically, whichever is the most convenient, on the inlet to your home following the stop valve.  Many of our customers have installed the Housetron themselves, however, for those that require a plumber the installation does not take long under normal circumstances.


Sizing is very important. For one to three bathrooms select the ½” Housetron.  For four bathrooms and above with high occupancy select the ¾” Housetron.

Yes or No

Technology / Product Knowledge:

If the technology behind the Housetron is of interest to you, we have an educational section devoted to explaining how all of our catalytic products work. However, if you'd prefer, here's a brief explanation:
With its unique special alloy core the Housetron works like a battery, generating a very small electrical current as water passes through it. This electrical current has the effect of neutralizing the particles of calcium carbonate in water that would otherwise cause scaling. These particles just stay in the water and instead of sticking to pipe work and hot water cylinders just pass harmlessly through the system and down the drain.
