We have PCI next week - a major issue is the q-stone (like essa stone) on the island bench
it's 2.4 metres long and about 900mm wide. when it was fitted it had a very obvious inverse bow.
this was discussed with BSS and the rectification to date looks like some very rudimentary packing. I managed to sneak in to house last week and run a string line across it - I can sit a couple of coins under the dtring in the middle. To me this is a major worry as the bowing cannot get better - can only develop further.
BSS has said this is the best you're going to get it. waddya reckon?
