The Novadrain 151 Series Flat Black Pop-Out Grate is designed to use with SN16 PVC-U DWV pipe. PVC-U material construction offers added strength and resists chemicals. Solid wall pipe technology optimizes the recycled PVC completely for efficient operation. Smooth bores and the precision joints ensures easy waterflow. Seal joints have been designed with high interface pressures that offer high resistance to tree root intrusions. This grate prevents leaking in ground water infiltration and sewage exfiltration caused by ground movement. Grate with a nominal size of 140 mm and measures 141 mm diameter x 17 mm.

  • Suitable to use for SN16 PVC-U DWV pipe
  • 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
  • Non-conductivity, PVC-U is a non-conductor of electricity, and is therefore not subject to galvanic or electrolytic action
  • 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
  • Grate only, use in conjunction with 172.100 finishing collar
