S-trap procedure — Securing the pan  

 

connector in place

1.1

  Determine the centre of the 

pan and mark the centre line on the 

floor and wall.

1.2

  Work out the setout required.  The recommended setout is 

150mm (setout range is 90-190mm).

1.3

  You may need to trim the large end of the plastic 

pan connector 

to fit the required setout. To trim, first remove the plastic ring 
and rubber seal, then cut pipe to size.  Refit rubber seal and 
plastic ring securely, ensuring a good fit.

1.4

  Position the pan connector into the floor outlet pipe (S-trap).  

The height measurement from the floor to the centre of the pan 
connector is 185mm.

1.5

  Slot the 

threaded section (with flange plate) onto the pan 

connector, ensuring that the flange plate is touching the wall. 
You may need to trim the threaded section so that it fits properly.

1.6

  Mark and drill the flange plate holes and secure the plate to the 

wall with fixing screws.  The pan connector is now installed.

 

Positioning the pan

2.1

  Use the centre line marked on the wall and floor to position the 

pan (see Step 1.1).  Push the pan into the installed plastic pan 
connector.It is recommended that wedges are used to support 
the foot of the pan during positioning.
