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)

Toilet stopped flushing, quick look and identified the problem. Found Stevenson plumbing had the diaphragm at a very good price. Ordered on the Friday and it was here on the Saturday. Excellent service Al Mclean (9 Sep 2017, 15:34)
