Rated 5 out of 5 by Does what it says I bought this to replace a small brick built structure installed by the builders who constructed our conservatory. It was a bit rubbish to start with and following a sewer collapse at the far end of our street, it had started to leak. Lovely!! The conservatory builders had to move the inspection chamber. Having carefully dug out the old clay sewer pipes, and the newer plastic ones that drained the conservatory roof, I was able to cut them reasonably accuratly with a large angle grinder and used rubber conversion sleeves and short lengths of plastic pipe to re-make the connections to the clay pipes. The flexible inlets of this chamber came into their own because with 4 half buried pipes to connect, a little give and take was required to get everything attached to it. In a new installation this may not be so important. Although I only needed 3 inlets and one outlet, this chamber provided me with a better range of angles for connecting my pipes, and since it comes with blanking pieces for the unused inlets, it made a dirty job a little easier. That can only be a good thing. 21 May 2014
