PermaSEAL Drainage Channel Adaptor

£8.50 Ex VAT
£10.20 Inc VAT

A special adaptor that allows you to easily connect PermaSEAL Drainage Channels to a natural drainage outlet or to a sump and pump system.


Basement Drainage Outlet Adaptor

The PermaSEAL Drainage Channel Adaptor connects PermaSEAL Drainage Channels to a sump and pump or to a suitable drain as part of a cavity drain system. 

One end of the PermaSEAL Drainage Channel Adaptor fits into the drainage channel and the other accepts a 50mm ID pipe . This outlet pipe then connects to either a sump and pump unit or a natural drainage point. Any water entering the cavity drainage system is safely removed, protecting your structure.

You can simply push the outlet onto the end of the drainage channel or floor drain. The adaptor forms a smooth and seamless connection without the need for tape. We have focused on an innovative design that means the internal surface of the adaptor and drainage channel remains flush. This avoids the unwanted build up of salts and silt and other debris that could cause issues. 

Installing Basement Drainage Outlet Adaptor

The basement drainage adaptor is easy to install as part of PermasSEAL’s complete drainage channel system. The adaptor simply pushes onto the drainage channel, and then connects to an outlet pipe that can take water to a suitable drainage outlet or sump chamber. 

The drainage outlet adaptors are part of our full range of PermaSEAL connectors and drainage channels:
