What are those sliders for?

[saveasteading]

 

I have successfully removed the bits from the Roca concealed cistern. There was an excellent video, although it was difficult to find.

further to an earlier post, I was very pleased to find an additional stopcock inside.  the space available is tiny but tit all clicks apart.  I dread dropping anything.

The quality is stunning, although we will see if it goes back together again 

I was expecting to find lime on the washer, thus being easy to stop the constant running, but there was no buildup. So I have given it a clean anyway and will shortly start the reassembly.

 

But I am concerned that I have moved these red sliders. I had assumed that they adjust the water flush quantity, but I can't see any effect on the mechanism.

The top one is labelled 'half, and bottom one labelled 'full'  ,  so that is simple enough.

On the red sliders the top one is marked  >POM<1-2

The bottom one is marked  <POM<1-3  I don't know what POM means.

 

and behind the sliders are scales the top one being 0 to 12, the lower one being  0-8

 

the picture attached is a screenshot from the video apparently set at zero for full flush and 12 for half flush.

 

confusing or what? I will accept any guesses but obv would love any real knowledge.

 

 

I  think I am going to put it back together with both high numbers.

 

Might see if I can reduce the fill level too in case that is the issue.

Adjusting the flush volume for short flush and long flush

 

get them in the right orientation and the flushes are both the same volume 

 

(expletive deleted)ing hate modern toilet flushes that are supposed to save water with a 3 L short flush and a 6 L full flush - no-one ever uses the short flush and it won’t clear a good piss from the pan

 

and don’t get me started on a number 2 that needs 2 full flushes to clear the pan

 

give me an old ceiling level thunderflush any day

That's  the query really.  

acc to the spec, the thing seemingly does, as suggested above,  3/6litre flushes    I assume that means up to 3 and up to  6 litre, so what the scales saying 0-8 and 0-12 means is  a mystery.

And POM does not appear as plumbing on any searches .

POM is the type of plasic the part is made from, is it not?

The good news first.

Roca have been very helpful in identifying the replacement part needed.

Their film of how to dissembleis slick and quite accurate.

Not so good :

it needs a new inlet as I have identified that it doesn't close off and apparently it isn't cleanable.

And I dropped a bit into the tank.It's a plastic spigot that the front plate screws into. Value about 10p. But the tank is so narrow that I can't get my hand in. If only they made the tank an inch wider or the part floated.

And roca have gone quiet on the part number. I might end up bodging a way of fixing the plate on.

 

I've been several hours doing this and now starting again. I wonder if a typical plumber would have known what to do.

 

Moral....beautifully made but impractical. The next house is having exposed cisterns and that is my advice to anyone.

A wet vacuum?   If you can see the beastie laying at the bottom of the cistern giggling at you then you may be able to suck it up and save yourself the tenpence…..
