Reclaimed and recycled water sources, and rainwater catchment systems are being specified and installed much more frequently as building and plumbing codes are updated to allow this as means for improving water conservation. The codes will require that the system be kept entirely separate from the potable water supply, and that the piping be color-coded and labeled to identify it as non-potable.

The water from these sources can be used for:

  • flush,
  • irrigation,
  • cleaning and laundry.

The new aquatherm lilac pipe system has been developed exclusively for these applications. The piping uses the same durable, corrosion-resistant polypropylene material that has been successfully used for hot-and-cold water distribution for over 25 years. This, combined with design modifi cations, coloring, marking, and independent third-party certifi cation by NSF International, make lilac the ideal choice for water conservation.

The advantages of the new aquatherm lilac-system:

  • corrosion resistant
  • well-priced
  • easy assembly
  • durable
  • high flow rate
  • colour-coding accepted in several countries

UV Resistance

Pipes and fittings made from fusiolen PP-R are normally not installed where subject to UV-radiation.

All aquatherm PP-R pipes and fittings have UV stabilizer to bridge transport and installation times. Maximum storage time in the open air is 3 months under Australian UV-conditions.

For the application in open air aquatherm offers composite pipes with an UV-protective layer made from black polyethylene, which excludes damages caused by sunlight.

Aquatherm PP-R fittings have to be protected against sunlight by using a black UV-resistant adhesive tape.

Painting the aquatherm PP-R pipes and fittings with an UV resistant epoxy based primer or lagging the aquatherm PP-R pipes and fittings with an UV resistant insulation is sufficient as well to protect the PP-R pipe system from UV damage.

Available types of pipe:

  • aquatherm green pipe MF UV
  • aquatherm blue pipe MF UV (on demand)
  • aquatherm blue pipe MF UV-OT (on demand)

Peeling of the UV layer

When welding UV pipe peel off the UV layer off the aquatherm pipe before fusion.

Push the end of the UV pipe into the guide of the peeling tool. Peel off the UV layer up to the top of the peeling tool. It is not necessary to mark the welding depth as the back stop of the peeling tool indicates the correct welding depth.

Before starting the fusion, check if the UV layer has been completely removed.
