Re: Grohe dual flush -- which button to push?

Tony Bryer wrote

Yep, same as mine. Hmmm...

Which makes me wonder about the need to have 2 different flushes.

OMFG - I give up! Go and THINK about what a dual flush is for. Does someone really have to spell it out to you? While we're on the subject, ever heard of a water meter or water conservation?

Brian Sharrock wrote

Oh, I understand the reasoning behind the dual flush system. In fact, having to push one button for a Number One and two buttons for a Number Two would make even more sense. If only that were the case...

But with this Grohe, it's the other way around: I have to push one button for a Number Two and two buttons for a Number One. Duh.

AIUI, ladies often use a single sheet of tissue after a Number One, so it's a pity they can't use the lower level flush.

Of course, the strength of flush will probably depend also on the pattern of flush generated by the design of the toilet pan, so it may well just be a function of my particular toilet that it seems so feeble.

I like the line they used in "meet the fokkers"

If its yellow let it mellow, if its brown flush it down.

I've had a quick look at the user manual/instructions and put it to one side for further examination once I've finished the rest of the jobs in the bathroom.

Useful information, thanks. I've made a note on my instruction sheet. :)

It's certainly not original to the film.

So do some men. I do at home where the toilet tissue is readily to hand. In some places (not seen it in the UK) you get tissue dispensers next to the urinals for this very purpose.

Where do you then put the tissues ? Stick them in your pocket ? Simon.

Especially as they use the loo 23 times a day, on average. (I couldn't find a half-smiley, so you'll have to take it on trust I am semi-serious.)

I *think* my no-name model can manage a sheet of loo paper. It certainly works fairly well, except the full flush doesn't always "release" and can flow water forever if you don't happen to notice. Someone also fitted the push mechanism the wrong way round so you have to reach past the big flush button to the small one (it's on the side of the cistern).

If you look through the pictures a few times it does become clearer.

It's certainly more hygienic than... other methods.

Oops! Are you on a water meter?

In a way, that sort of thing was what led me to ask this question in the first place. I was concerned that my controls had possibly been connected the wrong way round.

One thing I couldn't work out though was the diagram/instruction embossed upon the rectangular pop-out panels. I even went so far as to do a tracing of one of them but it still made no sense at all. Arrows going this way and that, fold here, don't bend there...

I'd not a clue.

Still, that's one of the disadvantages of buying something which is sold in multiple countries, I suppose. Far better if it said, in plain English, "Don't remove the side tabs." or whatever.

Hint. Download instructions for several of their products. Some have better illustrations than others.

Not yet. My stopcock is in a damn stupid place (under the floor, would you believe) and I've a small issue with standing water under there at the moment, so I'm waiting til that's resolved before I invited UU round to survey for a meter, which I would like them to install in the pavement if at all possible. Still organising my plan of attack on that one...

I don't have a Grohe cistern (sorry for the diversion), so can't advise. The mechanism on mine seems to be a single air-tube, and presumably there's some clever trickery to make that do two functions. (I'd guess it pushes air from both buttons, but one holds the pipe closed and the other opens it to the atmosphere, maybe).

Good luck on that one!

No problem. I'm just reciting the mantra: "Big button, big flush. Small button, small flush."

I've recently seen a flush panel in Amsterdam where there are two buttons - one with one raised dot on it and the other with two. Behaviour is as expected

The pan didn't have the turd inspection shelf either.

snipped-for-privacy@hall.nospam wrote

And, as you say, it's the *expected* behaviour.

The thing is, these flushes must be simple or (a) guests/visitors aren't going to know which button to press or (b) guests/visitors are going to press the wrong button because their system is different from this one.

Well, you know what they say: "Don't blush; look before you flush."

Just as a follow-up to my experiences with my first dual-flush WC, let me say that my 3-week old Grohe (38 690) cistern has just also failed to cut off after a full flush.

It's only happened the once so far, but...

What seemed to have happened was that (a) the flow of incoming water had dropped to a small fraction of its normal rate and (b) the outflow valve had stuck in the open position. So, there was a steady flow (about as much as you'd pour from a kettle when filling a teacup) into the pan and the cistern never filled.

Having used suckers to pull off the cabinet's access panel, I saw that there was indeed almost no water in the cistern. I waggled the various levers, tubes, floats, etc until the inflow suddenly resumed its normal amount. The cistern quickly filled and then shut off as normal.

My mistrust of this overly-complex mechanism seems to have been well founded. :(
