I have 3 questions relating to this. I have 5 Hepworth inspection chambers around my small garden. They are all identical and are 10.5 inches across, metal and have 3 flat head screws securing them (that have all sized up) My property only has one toilet.. First question, Why are there so many of these all on my property? (Am one of 60 houses on the estate which has 2 build styles, built in the late 1980's) Second question. What is underneath these inspection chambers? And third question. Water board and leak specialists could not open them band where frightened they may bust the lids! So how do you open up stuck solid screws on these Hepworth lids please.
