New domestic toilets - small cistern - WTF
Discussion
Just getting our bathrooms redone - incl new furniture. The old toilets that were taken out held 9 litres of water in the cistern, and would generally get rid of the bowl contents in one flush - occasionally 2 (maybe after a curry 
).
The new ones are 6 litres "to help conserve water". WTF! It now takes 3-4 flushes to rid the bowl contents. That equals 18-24 litres, as opposed to 9, but sometimes 18. Where's the sense there!

What the 
are you eating?!
If your toilet is perfectly installed so that the u-bend drains very "cleanly" into the soil pipe with the appropriate siphoning etc, then the flow from the small cistern works OK. But back on planet Earth, where the bog is often attached to the soil pipe by a horizontal run and a bend or two, and the bog doesn't siphon properly when it flushes, then the small cisterns are a complete waste of time.
What is particularly stupid is that if you sell someone a larger cistern, and it turns out the bog flushes perfectly well with a reduced volume, the plumber can always reduce the large cistern's working volume by putting a couple of house bricks in the bottom of it and adjusting the ballcock so it doesn't fill to the brim. Given the choice, who wouldn't choose to save a few quid each year by making a simple adjustment to their cistern if it turns out to be viable?

Yep - think that's my problem. It does a 90 left behind the loo, then a shallow run to the main house soil pipe ( about 4 ft), then a 90 right, then a run of about 1 ft, then into the outside verticle pipe.ATG said:

Yes, but who is organised enough to get round to doing it? Most people (OK, probably not on this forum, but in general) would want to call out a plumber to do the job! (And pay extra for special 'plumbers bricks' 
)This sort of thing really hacks me off... reducing the size/performance of things to try and "save" something or other to such an extent that the thing doesn't bloody work properly any more. Washing machines are another example... "saving water" and "saving energy" by using an insufficient amount of non-hot water for an inadequate number of rinses, so you have to put the clothes through another complete cycle but without putting any more detergent in in order to get all the soap out.
How utterly vile.

In our house, when we piss we don't bother flushing.Gassing Station | The Pie & Piston Archive | Top of Page | What's New | My Stuff
