Got a customer with a cracked cistern but it's a modern 6 ltr unit with push button flush valve etc, could be from b&poo can a replacement be sourced for this or will it be a complete new w/c
http://store.discontinuedbathrooms.co.uk/db/index.htm Other than these there doesn,t seem to be much about for your particular problem, ebay maybe if you can find the make,but if its a cheapo from B and Poo-they,re about 70 quid for the lot, Cheers Natro
