Compact Vertical Flue Extension ( Ø80/125mm) Nominal length 1 meters

First determine the degree of extension that causes discomfort and slightly flex the joint for taping. Shave all surfaces where tape will contact the skin or cover the skin with prewrap.
If your water source is heavily chlorinated then
many parts won't last long. Or if you have a lot of sand or grit or have a low
pH or "aggressive" water source then parts simply won't last as long
as the 'average' length. Also the quality of the parts matters. The replaceable
parts such as flappers and washers/seals generally will last at least 4 to 5
years on "average." If you use a bowl cleaner some flappers won't even
last one year. If your flapper has black "goo" on it then it is either
due to age or quality of your water and if it feels soft then it's best to
change it.
