Checking the Screwfix catalogue and see there are two types of ready made sewer chambers, the 450mm size and 270mm size.
I need a new chamber for my house, where a 4" pipe will join into the sewer leading to the public sewer chamber. Also a rainwater down pipe will need to join in to the chamber on the same side. So can I use the 5-inlet mini chamber, which would save me a bit of money. Adjustable mini chamber, 2 x risers and frame and cover = £64, Adjustable 450mm chamber same spec = £124, so the larger chamber is twice the price.
Also what advantage does the adjustable chamber give me over the fixed units?.
With the rainwater down pipe, what do I need on the bottom of it? Is it a low back P trap with a hopper above it???
Apologies for all the questions, but I know there are experts on here with good advice - thanks
