    Looking at the "Large Inspection Chamber Risers" I have found a manhole that has been buried 300mm under a block paved path for years the diameter of the cover looks to be around 500mm it says "PlastiDrain" on the removable cover, are chamber Risers universal fitting or do I need to find one specific to "Plasidrain"?
    screwfix list a floPlast chambers as 450mm (76369) and Toolstation list a Aquaflo (65574) one as 470mm, is this a internal for floplast and external for Aquaflo with both having 10mm thick wall?
