Hi I have a continuously filling cistern and i'm not familiar with the mechanism. its a dual button flush with a cable connection. water enters thru the grey cylinder. the red would normally shut the water off but lifting as far as it goes doesn't stop the flow or even slow it. how do i get the grey cylinder out without damaging it to inspect ? it's not obvious exactly where water is entering via the grey cylinder any ideas on why the water won't cut off ? do you reckon replacement is needed ? it all seems a bit rickety

I'm building a small extension with new walls on two sides... 2.50 x 3.00 http://imageshack.us/photo/my-images/69/sideelevation.jpg This plan is obviously not to scale.. I've been told by building regs I need to double the rafters around my two 800 x 1100 roof windows. At the moment we have installed 170mm x 50mm rafters with 250-300mm spacing across the roof... and with the span being being 2.50m. The window suppliers site seems to indicate they are happy with single rafters.. but has no clear info on installing to a new roof. Can anyone could point me to a place on the net for chapter
