Rated 1 out of 5 by from Connecting to older FloPlast I bought this to fit to an older FloPlast system installed about 8 to 10 years ago. Firstly this item came without a seal which is an extra £5 something. Secondly the whole riser was a tight fit in the older chamber. When the seal was in place this needed driving home with a block of wood and a mallet. Disappointing that it didn't just fit together easily and the additional cost of the seal, which used to be included, made this a very expensive item. Would not recommend for connecting to older Screwfix products / FloPlast systems.

Rated 5 out of 5 by from So easy to fit You do not need the silicone spray to fit this, they slot in very easily to the chamber base and into other risers if you are using more than one. I used two and it was the easiest thing to assemble ever, the base and lid all slot together perfectly. If you are using the lid that goes with this you don't need a sealing ring as the lid comes with one.

External Diameter ?

I need to extend an inspection chamber which has a internal diameter of 235mm and an external diameter of 250mm. On top of this I currently have an Osma 4D328 inspection cover. Will this riser allow to extend the chamber and still use the existing cover ?

raising 2 manhole covers

hi, can I use this to raise two manhole covers by 60mm each, or do I have to buy two of these.

Will this fit other makes of inspection chamber

We do not know the make of inspection chamber but it is plastic and 450mm dia. The house is 7 years old and we need to raise the cover by 200mm. Will this fit? Thanks Steve

Will this fit into a clay chamber base and give a good tight seal

Asked by: Gazza1240
There is no guarantee that the risers will fit into a clay chamber base. A lot of the chamber bases different sizes between manufacturers so are often not compatible.
