Toilet dribbles after flushing

[covehithe]

My mother has problem with her new toilet installed in her flat.. It is an Ideal Standard dual flush compact cistern (15 months old) connected to a Sani Flow. After flushing it continues to dribble, wasting water and the Sani Flow then powers up on a regular basis - particularly a problem for her at night time.
Is this a fairly simple procedure to cure this. I live a long way from her and can only pass the information on to the buildings "handyman" or is it a definite job for a plumber. Any help or advice appreciated.

thats a compact df014 flush valve.
the valves failing to shut fully after flushing.
try removing the upper part of the valve and cleaning the rubber seal first.

shouldn't be you must have atleast one wc on the main soil pipe before you can fit a wc with a sani.

Water usually trickles through into the pan due to the Seal on the bottom of the flush valve not sealing correctly.
This can happen for many reasons, most common is detrius around the rim of the seal, worn seals (take them off and reverse them), or mishappen outlets.

Usually to remove the seal, you will need to.

1) Turn the water supply off.
2) Remove the entire float valve assembly. 2 Clasps usually hold these in place. Holding the clasps at the top and squeezing them inwards releases the tooth grip at the bottom of the clasp allowing you to life the assembly upwards and out.
3) Clean the Seal and the porcelain around the outlet.

If the seal is perished, you may be able to get a replacement.

Thanks for the info.
"Seco Services" also suggested this as a possible way of curing the problem.
My nephew managed to get the flush valve out and found that the seal was contaminated with small amounts of rubbish that looked like scale. He cleaned the outlet and the seal. So far everything is ok
