Fienza Tono Tornado Flush Back-to-Wall Toilet Suite

We purchased two Tono back to wall toilet suites. Initially we experienced the complained about issues with flushing. There is nothing wrong with this series of toilets but the problem lies with the plumber who installs them as instructions are never read and so unflushed solid matter constantly causes blockages. If you read the instructions providing the plumber did not throw them out! there are two adjustments to increase the amount of water which will ensure 100% flushing without blockages. The factory setting is very conservative so minimal water is discharged on full flush with not enough water to fully push the solids beyond the bends.

First increase the total amount of water held in the cistern using the white plastic screw turning it clockwise. This should raise the total water level by about 12mm. The major adjustment is within the discharge valve housing. Remove the assembly by a ¼ turn anticlockwise and then take out from the cistern. Find the small adjustment assembly at the bottom. Unclip the slider lock with a tooth pick or similar then slide the adjustment all the way to the bottom. Relock the slider. Put back into cistern. Our measurements were originally 5 seconds of full flush water, with adjustment now 9 seconds full flush volume and zero blockages.

If the adjustments suggested are too complicated the simple solution to the flushing issue is to hold down the full flush button until the cistern fully drains and then you will have about 10 seconds of water which will certainly do the job but you need to use this method every time.
