Will Interflush fit my toilet? The Interflush was specifically designed to convert single flush plastic siphons to interruptible flushing. This being cheaper and faster than changing the existing siphon to say dual flush. The Interflush also provides 20% more water saving than dual flush. (Not for cisterns with flush handles at the sides which include high level chain pull cisterns. Not for push button operated cisterns, these have valves inside.) What tools do I require? All that is required is a cordless drill and a pair of side cutters, pliers or similar (not a knife). A No. 0 posidrive screwdriver, 4mm and 8mm drill bits are provided with the kit. Is it easy to fit or do I need a Plumber? If you consider yourself to be a competent person, you should be able to fit your Interflush™ in less than half an hour. Will it fit my toilet? The Interflush™ is designed to fit plastic siphons in cisterns with front mounted handles on either the left or right. Do I need to turn the water off? No. All you need to do is remove the cistern lid. Is it hygienic, does it clear the pan? Yes. Simply hold down the handle until the pan is clear. Is it guaranteed? Yes. Unlike most products in today's throw away society the Interflush™ is designed to last a lifetime. If, at ANY time, a part should fail, simply return for a free replacement.
