Cast Iron SimpleFIT Drainage System: A video guide to pre-relaxation of the rubber gasket prior to assembly

The SimpleFIT drainage system, made from quality cast iron, is ideal for traditional style, heritage or listed properties. Its clever, simple push-fit method of assembling the components significantly reduces installation time and, therefore, cost.

That said, to aid insertion of the SimpleFIT pipes into the eared or non-eared sockets, pre-relaxation of the rubber gasket inside the sockets immediately prior to assembling the joint is essential.
A short video demonstration always makes an explanation clearer than just words and still pictures, so we put one together for you below.

Video transcript:

  • To aid insertion of the components immediately prior to assembling the joint
    You will need:
    1. The relaxing tool
    2. The lubricant
    3. And the eared/non-eared socket with the logo up-side-down
  • Apply lubricant to the rubber gasket inside the eared/non-eared socket
  • Apply lubricant to the open end of the relaxing tool
  • Insert the relaxing tool into the socket
  • Slide it up and down over the gasket sealing face three or four times
  • The gasket will now be temporarily softer and enable easier assembly
  • Add a small amount of lubricant to the pipe/fitting
  • Turn the pipe/fitting over and insert into the socket

Additional Information:

  • The same process will need to be repeated for the other side of the socket before the next length of stack/fitting can be inserted.
  • Using at least one eared socket on each fitting will enable the system to be anchored securely to the building.
  • Installation should be from the bottom to the top of the soil stack with, typically, a length of pipe, boss pipe or branch at the base of the stack.
  • The first pipe, boss pipe or branch should be connected to the underground drainage system and have an eared socket fitted to its top to ensure a secure base and stability of the pipework before proceeding further.
  • Subsequent pipes/fittings installed vertically above this point should incorporate at least one eared socket.
  • On branch ‘arms’ (i.e. off the vertical) we recommend the use of a plain socket to provide the correct aesthetic.
