Product Information

This syphon diaphragm washer suits standard and 3 part versions of the oblong shaped Derwent Macdee Metro WC toilet cistern syphon.

Approximate dimensions : 140mm x 82mm, centre hole 14mm diameter.

Older versions of the diaphragm had an extra couple of tiny holes. If needed, you can make these using a sharp tool.

Using this replacement diaphragm washer to repair your syphon can fix many toilet flushing problems and is a great alternative to buying a new siphon.

toilet syphon diaphragm washer

Thanks to Stevenson, not only did I not have to call plumber, but could repair the flush mechanism myself, sparing landfill some plastic as the whole thing did not then need replacing. The part arrived within 2 days, excellent service, excellent company. Thank you Carol. carol hutchence (9 Feb 2019, 13:43)
