Too powerful flush

[izzy eckerslike]

Just fitted our new cloakroom toilet with hidden cistern behind stud wall but the problem is the flush is too powerful & splashes over the rim a bit

Reducing the amount of water in the cistern has minimal effect.

Is there a means of slowing down the gush of water that comes down the curved flush pipe somehow by fitting something inside it?

The design of the toilet bowl is probably the main cause of this as it has visible outflow holes near the rim which is completely different to our other toilet where all the water comes down from under the rim itself

You always take a chance if you mix bowls and cisterns from different sources. The only way I can think of to reduce the flow is to sleeve in the downpipe. A short piece of 1.25" waste might do the trick.
Friend of mine found a big lump of putty in this pipe in his new house. Made a huge difference to the flush when he eventually found and removed it.

It could be a faulty pan, certainly it's not uncommon, with all the european rubbish flooding the country.

Could also be the pan is leaning forward, and the front edge wants raising.

It's just occured to me that maybe the answer is obvious,lol

If I just reduce the flush pipe length & lower the cistern then hopefully it will reduce the surge of water? going to try it anyway

Lowering the cistern right down just above the bend worked wonders, flush is perfect now with no overspill, luckily it's fitted with a remote air flush button which remains in it's original position
