"There is no way in the world anyone laying traditional concrete pipe can keep up with Costall Drainage- Hardiepipe™ concrete pipes gives us an unfair advantage"
Jason CostallProject Manager - Costall Drainage
Reducers are a very economical way to change pipe size in stormwater lines, possibly eliminating the need for a pit.
Reducers are machined externally to the spigot dimension of the largest pipe that is being installed and internally to the smaller pipe i.e. 450mm external diameter and 375mm internal diameter.
To reduce more than one diameter size the installer must use multiple reducers; for example to reduce from a 375mm pipe to a 225mm pipe the installer will require a 375mm to 306mm reducer and a 300mm to 225mm reducer - these reducers will fit inside each other.
NOTE: Reducers can also be used with rubber ring jointed unturned adaptors.
Installation Details
1. Fit the reducer into the adaptor on the end of the pipe reduced.
2. Fit smaller diameter pipe into the other end of the reducer.
