Frequent Asked Questions

Calmat is suitable for all pipe materials: iron, galvanized iron, copper, steel, stainless steel, plastic, PVC, PE-X, compound pipes (any material mixture) etc.

Yes. Plastic and copper pipes are prone to calcification, too. The smoother a surface is the longer it can resist the process of calcification. It may take longer until plastic or copper get a first layer of scale. However, once that first layer has built up, the scaling process proceeds just as fast as on any other surface or material.

The winding direction (either clockwise or counter clockwise) doesn’t matter, each impulse cable can be wrapped either way.

The number of winding around the pipe does not have to be necessarily equal to each other and the unit will perform well regardless. Winding the cables a few inches away from the Calmat device is ok as it wont affect the transmission of the electrical impulses. Ideally we recommend winding the impulse cables as tight and neat together as possible for maximum performance.

Does the orientation of the unit or cables does not matter! Calmat can be installed vertical, horizontal, even upside down and is going to work the same. It will treat the water from the point you install the unit on wards and will protect the rest of the piping system.

Calmat should be installed on your main line coming in after any pressure tank, sediment filter or whole house filter you may have; and before the split into both the cold line and water heater leading to the hot line. Anything else including a water softener, RO system, UV filter would be fine afterwards.

Calmat will treat your whole piping system downstream from the point of installation forward and about 10m backwards.

After the installation, you will see some or all of the typical effects. Depending on the water composition one effect may be stronger than the other. We have customers that have seen some effects right away, others after a month, and some others after a few months. To have the whole limescale removed from your piping system usually, it can take from a few months up to six months. Please find attached a description of what to expect.
