Can you please tell me where in South Australia I can source a zurn flushometer to replace my 2 ailing Unibra toilet systems. They are approx. 50 years old and are finally giving up their long and loyal performance. No-one in South Australia seems to know what I’m talking about when I ask for a Unibra repair kit so I presume there is no such thing – anymore!!! However, I understand that Zurn Flushometers are still on the market but where???
