Who is PTH Water RSA?

Domestic use

PTH Water RSA has been actively engaged in water treatment in Southern Africa as far back as 1996 and have established a wide clientele on the sub-continent since then, and our track record is beyond reproach.

Marais Massyn started Water Softening RSA in the ’70s in Bloemfontein, South Africa, supplying cation-exchange, resin-driven water softeners throughout South Africa and the then South West Africa (now Namibia). Although serving their purpose at the time, there were certain disadvantages associated with water softeners that use salt.

These old-fashioned water softeners had to be regenerated with a brine rinse, which resulted in a run-off harmful to plants, as it brackened the surrounding soil. The recharging process was time-consuming, time being a commodity which modern society no longer has. In addition, it was subsequently established that the sodium released into the water by the resin during this process of cation exchange, was potentially hazardous to users’ health, in that it was associated with high blood pressure and certain heart ailments.

These factors resulted in the preference of chemical-free softeners, instead of resin-operated softeners.

With the advent of electrochemical water treatment internationally, the emphasis started swinging away from the so-called saltwater treatment towards more environmentally friendly products.

South Africa was ready for chemical-free water treatment. There was a massive demand for a product that was easy to install in-line into any existing closed water system, that was unbreakable, compact, and above all, chemical-free.

In 1995, contact was established with the producers of the PTH product in Israel, HOP Engineering in Tel-Aviv. Water Softening RSA was awarded the distribution and marketing rights for the revolutionary PTH.

On his return from Tel-Aviv, Marais Massyn said that the PTH Water Improver had all the qualities and characteristics for it to be of considerable use in the southern African environment.

PTH supports NSRI

In 2005, PTH Water (Southern Africa) founder and owner, Pierre Massyn, turned into Crew and Fundraiser for the NSRI (National Sea Rescue Institute).


He hoisted the NSRI banner on top of Mount Kilimanjaro for the first time, raising approximately $400 000 in a self-funded expedition.

Pierre has had many adventures. The most recent one included travelling to Cape Horn, the southernmost headland of the Tierra del Fuego archipelago of southern Chile. Read more about it here (only in Afrikaans).

Then PTH took South Africa by storm...

Since those early days, thousands of PTH devices have been installed in homes and factories, dairies and laboratories, gardens and restaurants, and even mines, all over South Africa.

PTH is widely used by some of the most prominent names in the industry

These include Samsung International, De Beers Mines, Nasionale Pers, Rossing Uranium, South African Breweries, Eskom, South Bakels,

Koogans Plastics, Marine Oil Refiners, Sanlam,  Polyoak, Marine Products, Kentucky Fried Chicken and many others.


The Coca-Cola factory in Kimberley purchased the product in August 1997.


The South African Navy is another satisfied user, as is the luxurious Beacon Island Hotel in Plettenberg Bay.


The prestigious University of Stellenbosch has tested the product and is currently using six of the devices.


The product is also endorsed by the University of Cape Town as well as Ben Gurion University. The Grain Research Institute of the University of Potchefstroom uses six PTHs on wet walls and speaks highly of the product. Read more about it here.

Windmaker Waterversagting CC was established in 2007 to cater corporately for the vastly expanded business. It is now trading under the name PTH Water. By 2020, there were more than 10 000 PTH units of different sizes in operation in South Africa and other countries, including Namibia, Botswana, Zambia, Mozambique, Morocco, the UK, France, Australia and even Mongolia.

Utilising its comprehensive network of distribution throughout South Africa, Namibia and the rest of Africa, the PTH team can service clients almost immediately.
