cheap price easy to install, cheap price, time will tell about reliability. 20 Mar 2015
Opella Dual-Flush Siphon I bought this to replace an existing one which had a torn diaphragm. It was easy to install in about half an hour and works better that the original did from new. Like the dual flush option and the fact that it has an internal overflow so will just drain down the toilet instead of through an overflow pipe. 13 Mar 2015
