You need to ensure you purchase the correct height otherwise you will not obtain optimal flush AND the syphon may not fit into your cistern (and stop the lid closing!). There are 2 ways to identify which size syphon you need:1. Installing a Turbo 44 for the first time or replacing a different syphon with a Turbo 88: To find the correct height of the required syphon for a cistern, measure the depth of the water level line, within the cistern, normally marked at the back of the cistern, and then add 1 or 25mm to this measurement. This will give you the height of the required syphon. (Cisterns fitted before 2001, would have an original syphon in them that would be approx. 1 or 40mm taller than the current requirements).See the Dudley video here on how to measure the water line.2. If you have an existing Dudley Turbo 44 and are confident you have the correct size syphon for your cistern then you can just measure the syphon to enable you to choose the correct syphon: See the last photo on this listing which shows dimensions. Where it says 'HEIGHT' that is where you need to measure on your old Turbo 44 syphon to enable you to correctly purchase the correct size syphon. Basically take the measurement from the bottom of the flange of the threaded tail (where the threaded part meets the moulded part that is almost in line with the oblong bulkier part of the syphon to the spillover point of the syphon (which is the bottom of the oblong bell part/moulded ridge on the domed cap at the top end of the syphon). When choosing a syphon the height stated will be the height to the spillover point and not the overall height of the syphon. (i.e. an 8 syphon would be 8 to the spill over, whereas the overall height would be 10) Below we have listed the possible height sizes and which syphon size that aligns to: HEIGHT cm(measure from bottom of flange of threaded tail to moulded ridge on domed cap.
