Hi. I recently visited relatives abroad where plumbing spares and knowledge are sparse. There is an Armitage Shanks ASA 180 9 litre lavatory low-level cistern with a faulty flush mechanism. It's aroung
15 years old probably. It says DPE (or perhaps OPE) Maxiflush on it. It is fitted centrally and raised by a side lever. The washer underneath is worn and that is apparently allowing the water to leak into the basin. Water is scarce there so cannot be wasted.The washer is approx 2-3 mm thick, internal diameter 28 to 30mm and external diameter 80mm.
Any ideas please on a suitable replacement mechanism or spares?
Thanks- Bill
