Derwent Macdee Metro Rapid Square Toilet Cistern Lever Flush Syphon Diaphragm Washer 10120568
If your Derwent Macdee Metro Rapid square syphon unit isn't flushing properly, it could very well be that all you need is a new diaphragm washer. Many make the mistake of purchasing an entire new syphon unit as soon as there are any flushing problems.
Typically, it's just this washer that needs to be replaced to make your toilet flush like it's brand new. Purchasing a replacement diaphragm washer instead of an entire syphon unit can save you a lot of money (and potentially time and effort) in the long term.
We usually advise purchasing a couple of these washers so in the event that this part fails again in future, you've already got one on hand.
Suitability: For use with Macdee Metro square syphons.
Manufacturer: Derwent Macdee / Wirquin
