Side sump box complete with outlet

  • Ensure the gutter around the side sump box is clean and dry. Blow dry with heat gun if damp
  • Continue to roll the liner two metres beyond the side sump box ensuring the liner is pressed firmly into the gutter creases. This will prevent air pockets and form a solid base to weld the side box to the liner
  • Using a Stanley knife, cut around the side sump box removing the section of liner
  • Pin the liner either side of the side sump box, one fixing 35mm into the gutter sole from the gutter crease and 35mm up the gutter slope from the gutter crease
  • Using the 200mm rule, pin the liner every 200mm across the gutter sole and up the gutter slopes if required
  • Ensure Sharmans Fixing Caps are installed over all fixings prior to welding
  • Push the side sump box through the hole in the liner ready for welding
  • The weakest point of any weld is the crease lines on the gutter sole. Weld the side sump box at these points first
  • Fully weld the flange on the side sump box to the gutter sole followed by the gutter slope to complete the installation
  • Allow the sump box to cool before probe testing the weld
  • Any un-welded area’s will have to be re-welded and again probe tested once cool
