Dual flush toilets waste water

Interesting story. The source seems respectable.

Billions of litres of water are being wasted every week because of an innovation intended to cut water use.

 

About 400 million litres of water are estimated to leak from UK toilets every day.

 

But much of this can be blamed on dual-flush toilets, designed to save water, the BBC has learned.

 

One water company says dual-flush toilets are now wasting more water than they save due to a combination of leaky mechanisms and confusing flush buttons.

 

Dual-flush toilets allow the option of a small or large flush - typically four or six litres - to only use the water necessary for urine or faeces.

 

Water-saving organisation Waterwise estimates that between 5% and 8% of toilets are leaking and says most of these are dual flush.

 

Andrew Tucker, water efficiency manager at Thames Water, the UK's largest water and sewerage company, says the problem is getting worse as bathrooms are done up.

I hate them, another invention that just doesn’t do what was intended, I find the full flush is never enough and normally flush again after I’ve washed my hands, so using twice as much. ?‍♂️

Just heard on r4. Amount of times half flush packs up on cheap bogs. Everyone I know full flushes

The toilet equivalent of the NEDC fuel consumption test.

 

On paper they use less water, in reality they don't.

True this. I’ve got one leaking at the moment. Seeing as it would cost £100+ for a plumber to fix it, I’ve let it leak.

It's not "dual flush" that is the problem, it's the modern release valves.  These often leak a trickle regardless of whether they are dual or single flush.

 

Lets all go back to syphonic flushes. They did not leak.
