I am conversant with UK plumbing but the different plumbing fittings in Australia have me stumped. For example, I want to change the old taps in the bathroom, that are dripping, with ceramic disk taps. The problem is that I cant remove the tap body shrouds to gain access to the tap body and I'm reluctant to force things I don't understand. I believe that there might have been a problem in the past because the shrouds show signs of having been attacked with stillsons.
Because there are no isolating valves the only way I can turn the water off is by using the garden stop-cock by the meter. If I inadvertently damage anything,the water has to stay off until an emergency plumber calls. Reluctantly I am going to have to call in a professional plumber
