Has anyone tried save a flush?

Hi,

I installed a new bathroom for my client recently who swore by these - Free Flush Water Saving Device | Fab Free Samples just wanted to know if any of you have used these before? and if they are any good?

Cheers

Just put a brick in the cistern

worst products ever, cisterns are designed and tested to flush according to written standards at the rate per flush that they were made too. These things will reduce the flush but as soon as you realise that every now and then you have to flush again it defeats the object

Advising to save water by putting a brick in the toilet will have blocked more U bends than people will readily admit.

Low volume flushes defeat the object in my opinion, save water by limiting the litres of water per flush but have to flush 2-3 times :6:

Hello All,

I agree with the Members comments above.

Another consideration is that the volume of water discharged in a W.C. flush has to be enough to carry the `Solids` along the drain run - not enough water entering the drain in a flush could easily just run away leaving the solids [excrement etc.] in the drain run not far away from the bottom of the Soil stack or ground floor drain connection.

Hopefully other flushes not containing any solids would move any build up but in a Home where only Women lived the build up of excrement and toilet paper could easily get worse as women use toilet paper with every flush.

I have encountered exactly the above in a Home where the specified W.C. cistern [supplied by the Homeowner] had a very small volume flush - specifically requested by the Homeowner against my advice.

After diagnosing the problem - the drain actually blocked up - [I had told him in advance this could happen] and because the Homeowner did not want to replace the W.C. / alter a tiled floor my only advice was to carry out a couple of additional flushes every time they used the Toilet.

This definitely negated the water saving properties of their new low volume flush W.C.

On this subject Who remembers Syphonic WC's?
Brilliant.

Ok it was a good 2 Gallon flush but Sucked everything out ! You flushed once !

I often think when I hear people flushing twice, That they just thrown more than 2 gallon down the drain because the modern loos are rubbish compared to the Syphonic.

Getting rid of them was due to waste water and regs, I bet we use more water now !



Sorry OP, I digress no i haven't used one of those things.

Around here they were called Water Hippo`s and given out FOC by the water company, It was just a bag of air!

Ok on 9L cisterns but not 6L. They caused all sorts of problems where a macerator was fitted because macerators do not suck waste in, they need a good amount of water to pick up and carry the waste matter into the cutting chamber. The Syphonic toilets supplied the water with too much force which then caused another problem.

I've seen just about every water saving device for W'Cs and urinals including Waterless urinals.
I work in commercial buildings so see a lot of energy/cost saving ideas.

Almost without exception they are all useless and cause more water to be used.

Bags, granules, bricks, blocks and the dials drilled into the top of a syphon in a 9tlr either cause jamming or convert the useful flush to useless.
Half flushes aren't any better when the get misused.

Anything saving water in a 6ltr is pointless.
6ltr was set as the absolute minimum required and pans were designed to make best use of it.
Why reduce it even more.

It's not enough generally, as above it ends up with 2 flushes totalling 12ltrs.

And don't even mention Flexi pan connectors.

JOKE!
i did a boiler sercice on friday and customer asked me to look at the loo as he cant flush no#2's away properly..

looked inside and there was one of those bags, i threw it out and he presto works perfectly.
if the toilets designed to use the fill volume indicated then why muck about with it. its like that because end of.
if they want to save water then go dig a hole in the garden!

 

[REDSAW]

the only water saving device that works for a toilet is to route the basin waste into cistern!!!!!!!

You know what I thought it would be a load of rubbish lol, I wont bother then
