The Marley Pro-fit System is a polymer-based hot and cold plumbing system that offers contractors a comprehensive solution for both residential and commercial installations. The System is JASWIC approved and has been tested and rated in accordance with SANS ISO22391 for hot and cold water supply systems. Affordable and easy to install, the system ensures that there is no corrosion or scale build up. Marley Pro-fit can be utilised on many different applications, including the Latco Pressure Control Valve range.


Converting to a new system often raises concerns, in particular the initial costs incurred and the required training. Pro-fit hot and cold technology is not expensive, requires minimal training and offers many advantages.


Features & Benefits of the Pro-fit Hot and Cold Water Plumbing System

Ease of Installation

Contractors enjoy the ease with which typical installations may be undertaken and the increased productivity. Joints are easily established without the use of highly skilled artisans. A typical residential hot and cold water pipe installation may be completed in as little as half the time required using traditional installation methods.


Due to the ease of installation and reduced time needed to complete the Pro-fit installation, contractors can enjoy savings due to increase in productivity.

Quieter Plumbing

Research shows that the public demands quieter plumbing.  Pro-fit is able to achieve reduced noise levels without over-capitalising.

Healthier Water

PE (Polyethylene) has been widely used for the safe transport of potable water for more than 35 years with no harmful leaching of elements into the supply line.

No scrap value

Conductor and copper theft is a grave concern for many contractors during installation. Polymers have no scrap value and reverting to such systems will resolve the issue of theft.

Advanced Materials

Pro-fit piping is manufactured from the highest grade PE-RT (Polyethylene with Raised Temperature resistance). The material is tough, puncture and tear resistant and able to withstand the pressure and temperature issues encountered within hot and cold water supply systems.

Pro-fit fittings are manufactured from PPSU (Polyphenylsulfone) or from DZR Brass where a transition to metal is required.

PPSU resin is exceptionally tough and durable with addtional benefits:

  • High heat resistance
  • Long-term thermal stability
  • Resistance to prolonged hot water exposure
  • Broad range of chemical compatibility

PPSU has been used extensively in hot and cold water supply systems and medical applications requiring repeated steam autoclaving.
