What the requirements these days regarding the flush on the WC.
Are they all dual flush water saving cisterns and push button function?

I think, off the top of my head. You should always use water saving flushes. Some older toilets will not work if you install these though. So if its a new toilet always a water saver if older try a water saver but be aware you may have to change again.

You need to ensure the toilet will work with a reduced flush. Had to replace an entire toilet for a mate after he got a plumber out to sort out the issue with his flush. Plumber (qualified, long time established) charged a fortune and fitted a flush not suitable for the toilet. Therefore the water would not flush anything away and would often rise up in the pan.
 
It will be a new WC that is being installed, just seems that all most all are now push button rather than lever/handle flush, with water saving flushes.
What is the requirement for flushing capacities?
I remember the old cisterns allowed for a 9l flush, then I believe it went down to 7l. Is it something like 4l now for a full flush?
 
Most new loos will work to 6/4. 6 litres full flush, 4 litres for number ones or small poos.
You are not allowed to fit a new loo with greater than a 6 ltr flush.
I could sell one, but it's against regs to fit them. (1999-ish) More UK legal logic!

Loos are available in the UK nowdays that will work to 4/2.5.....if you look hard enough. In Scandinavia they are the norm.

Sounds like an old syphonic WC - so a new £60 bog in a box using 6 litres or less is actually not a bad solution . Whole job for a Ton inclusive, knowing Naz. ;)

You're my hero Naz. Remind me again why these qualified, long time established plumbers:
(a) Don't want to take you on, and
(b) Are "long time" and "established" and trading effectively.
 
Naz, if he was your mate, why didn't he ask you first???????? :confused:

Simple reason was his dad got his mate to come and sort the toilet. Didnt bother asking the son if he knew anyone.

So yet again i have had to correct a job which was bodged up by an experienced plumber who charged £100 to change a blooming flush which turned out to be unsuitable for the toilet.
