Thanks for the replies gents :D
Pretty much all the plumbing in the house has been renewed over the years, its just the incoming black plastic water pipe thats original.
I will need to get it sorted in the near future as we have put the flooding through the insurance. 3x4m new floorboards...
G'day
I have just found a slow leak that has knackered half my kitchen floor due to the stopcock drain off washer dying :o
Had a plumber in who told me as my house is 1960's vintage none of the modern fittings are compatable.
Managed to repair the washer in the drain off bit so stopped...
