I'm looking at replacing a very old Maxmatic waste disposal unit with a sink basket strainer fitting. The Maxmatic was installed (by me) over 40 years ago and has given excellent service, but has now failed. We don't use it much now as we recycle the vast majority of food waste. So, as it has failed we thought we might as well ditch it. In fact, the only reason for getting rid of it right now is that it will likely get clogged up with bits and pieces that still get down there. So I looked around for sink basket strainers and came across some that say "Replacement waste kit for sinks manufactured AFTER September 2008". So that set me thinking about things like: What has changed? What do I need to be wary of? Can I even get a sink basket strainer to fit my old sink? Be grateful if anyone can shed any light on the matter. Cheers, Barry Man

And a few more photos giving the overall context. As is clear, the roof falls towards the rear and water runs off at the sides of the rear onto the meain roof.

Couple more photos taken at same time, but zoomed out a bit more. HTH. Would have to get the ladders up again to do more.

Recently had flat dormer roof covering replaced (new insulation, decking and felt layers). Having got up there and had a look I see two areas of possible concern with the works. Best illustrated by the attached photos. In both cases the issue relates to the corners where the flat roof joins the main roof. In the left one, the 'felt' seems to be lifting away from the lead that goes up under the tiles, plus the lead seems to be rather up in the air. In the right one there is what appears to be exposed bitumen surface (selvedge?) - i.e. not covered by mineral granules. Would appreciate any thoughts / observations. Thanks, Bazza
