The Novadrain 178 Series 100 mm DWV Slab Repair Coupler in light grey, is designed for use in various plumbing and piping applications. It helps to do in-Situ repairs to the damaged pipe work by allowing a joint of the slab repair coupling directly into the bore of the riser pipe. It is made of PVC-U for added durability. This F/M coupler connects using solvent cement joint. It is suitable for use with SN16 PVC-U DWV pipe.

  • Perfect for various plumbing and piping applications
  • Extremely smooth bores, precision joints, and lack of internal projections encourage flow capacity over the total life of the system
  • Flammability - PVC-U does not support combustion and 'Non-conductivity, PVC-U is a non-conductor of electricity, and is therefore not subject to galvanic or electrolytic action
  • Connects using a solvent cement joint
  • Iplex DWV elastomeric seal joints have been designed with high interface pressures which, when coupled with smooth, impervious PVC socket and spigot surfaces, provide high resistance to tree root intrusions
  • The lightweight of Iplex DWV pipes together with longer pipe lengths, flexibility and the use of narrow trench widths minimises installation costs
  • PVC-U has excellent chemical resistance to hydrogen sulphide and the acids or chemicals normally expected to be encountered in sewer drain and waste applications
  • The spacing of manholes can be increased due to reduced incidence of blockage and increased flow rates
  • Ground water infiltration and sewerage exfiltration due to broken and cracked elements and joint openings caused by ground movement are significantly reduced
  • DWV sanitary drainage fitting used to do inset repairs to damaged pipe work vertically exiting a concrete floor slab penetration
