Does the Job - nice and cheap Does the job for a bargain price - Easy to fix but something worth a mention - the screw thread at the bottom of the unit is long which for most situations is handy or not a problem, but for my close coupled toilet with a shallow waste entry I needed to cut down the thread after installation because of blow back - took a little while to suss this out as I'm not a plumber but after eliminating all else this was the cause - all is now well in the toilet world. 20 May 2015
Nothing to critisise. These slot in and do the job. Good price and fast delivery. 20 May 2015
Converted Existing system Replaced traditional system of existing toilet with this dual flush system and internal overflow. Fitted stub/blank to outlet pipe connection and all seems to be working OK. 17 May 2015
