Will Interflush fit my toilet? The Interflush is designed to convert single flushing, plastic WC siphons to interruptible flushing on toilets with FRONT mounted HANDLES. It needs about 20mm of space between the siphon and the underside of the cistern lid. (Not for cisterns with side handles, chain pulls or push buttons.) 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.
