Dudley Turbo 88

Post by dinger » Thu Jun 29, 2017 10:04 am

Fitted a Dudley Turbo about 6 months ago and it worked fine up to today. Now it only gives a half flush irrespective of how the handle is operated. Took it out and had a look at the membrane and it's 100%, both the white plugs are in place so what is causing this half flush problem ? Got me stumped.

Stumped no more. Emptied the cistern to look for any bits that may have come off the syphon and found a clear plastic plug about half an inch long. What the bloody hell is this, thought I ? Took the syphon out and found a hole on the side of the syphon just below the flushing hook, the plug fitted so filled the cistern, flushed it and it worked ! Question: Why make a hole and then plug it up ?? Makes no sense.

The plugged holes are to allow it to be reconfigured for different flush volumes. The default setup when you buy one is 7 litres. With the white plug removed it's 6 litres, and with the plug fitted and the little yellow flap closed, 9 litres.

The correct setting depends on the design, and age, of the pan. After 2001, the pan should fully flush with 6 litres of water. Between 1993 and 2001, 7 litres. And pans fitted before 1993 will usually need the full Niagra - 9 litres.
Haste is the enemy of quality.
