Rated 5 out of 5 by Siphone Excellent product used this siphone for more than 5 years with no problems or call backs as good as more expensive products 27 Aug 2016
Rated 5 out of 5 by No frills, does the job Used this product to replace an old malfunctioning siphon. Never had to fit one before, but I followed the good clear instructions printed on the back of the bag it came in and the job was successfully completed in no more than half an hour saving me a plumber call out charge. Not sure how long it will last in a well-used school toilet block, but not a lot to complain about at this price. 5 Jul 2016
Rated 5 out of 5 by Leak fixed Old Siphon was leaking from the bottom as the rubber washer had perished. Cheap enough and easy to fit although I did have to trim a bit off the rough edge at the top as it caught on the ball cock arm. Smeared some clear sealant on the top and bottom of the rubber washer to ensure it seals well (being an old cistern). Bought in conjunction with the close coupling kit which was also easy to fit. Job done on a Sunday morning for less than 15 quid! Thanks Screwfix for being open. 29 Jun 2016
Rated 3 out of 5 by Too big for toilet The siphon seemed fine, problem was it was too big for my compact cistern, the distance from pipe outlet hole to cistern side wall was smaller than siphon so could not fit, so be aware if have a compact cistern but traditional flush. Ended up repairing old siphon with a new membrane 20 Jun 2016
