Rated 1 out of 5 by 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. 23 Jul 2015
Rated 4 out of 5 by so easy to use Great product easy to use and reliable. Quick to install and quality 15 Jun 2015
Rated 5 out of 5 by 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. 13 Aug 2012

This can be cut to your size in 60mm increments, by cutting above the large flanges.
