I need to connect to the mains drainage. The run from the house is approx 20 metres with good fall. I need to include 1 manhole or inspection chamber at a change of direction. Where is best to source materials and does anyone know where I can get the french guidance for install, ie depth of pipe, connection etc, manhole requirements I'm familiar with British below ground drainage, just need to understand the french system. any help much appreciated
