Opella Dual-Flush Siphon 4.5 5 119 119
value toilet siphon I was looking for a toilet part. And seen some really bad reviews for this identical siphon in many other large retail stores. So i decided to take plunge and buy from screwfix as this was the cheapest. This one is about 1" shorter than my old white siphon with added feature of half flush which is useful. Fitting was easy after slight adjustments with c-link and ball float arm then after i was pleasantly surprised to discover it works even better than my last toilet flush with added benefit of half flush. I was nervous at first thinking it may be difficult to fit or i might get leakage and it only took me 30 minutes to complete But all in all i am happy with this product does the job i would recommend this product my advise would be take your time when fitting otherwise you might need to call a plumber! 1 Mar 2015
Siphon at its best This siphon is excellent value for money, simple to fit and allows different flush volumes to suit the customer. 13 Feb 2015
Good piece of Kit Just the job for my low-flush system and at a great price, for close-coupled systems you will need the extra associated parts kit. 11 Feb 2015
great water saving device This is brilliant if you need to save water with the half flush system or full flush It also is good because it does away with any worries as it has an inbuilt overflow 10 Feb 2015
