Hi, first post here.
I'm looking for advice on:
1, Whether to buy a syphon or a flapper valve for a toilet cistern. Which is most reliable? Which is most efficient use of water?
2, Dual-flush systems. Whether syphon-based or flapper valve-based, what is available, and how intuitive are they to use, without needing instructions left by the toilet for visitors?
Some more details:
I need to buy a new syphon or flapper valve to replace an old syphon in a cistern for a toilet, close-coupled to the pan if that makes any difference. The reason I want to replace it is because I want one with an internal overflow, which I understand they all have these days, and I'm also interested in dual-flush systems. Although I've done lots of searching, I still need some advice about what to buy.
Firstly, should I buy another syphon or a flapper valve instead? I've read thread //www.diynot.com/forums/viewtopic.php?p=65182 from 2004 but are there any more opinions? I've heard flapper valves can be unreliable and need replacing often, which is not what I want.
I'm quite interested in saving water so am interested in dual-flush systems, where you can do a smaller flush for #1 rather than #2. I've seen flapper valve systems with two buttons which seem nice and intuitive to use, but are there any of these that will fit into the hole left on the front of the cistern by removing the lever? All the ones I've seen need a big hole, usually in the lid of the cistern, and I don't really want to change the cistern or lid.
Alternatively, what about dual-flush systems which can work with a lever, either with a syphon or a flapper valve? I believe they were tried several years ago with flush and release the handle for #1 and a flush and hold the handle for #2, but as people were used to flushing and releasing, they thought that their loo wasn't working and ended up flushing twice, wasting more water.
So I was interested to read about the Dudley Turbo 88 Duoflush http://www.thomasdudley.co.uk/turbo88.asp which works the other way round (short 'normal' flush for #2, long flush for #1). I like the sound of that because it means that people living in the house can learn the system, but visitors can use the system without having to have it explained to them and can just flush as normal and it will at least work for both #1 and #2, even if it does mean using a bit more water. (Of course, I would have to leave the instructions for future residents if I moved out, so that they know they can save water.) Any other similar systems, or is it just the Dudley Turbo 88 that works like that?
I have other questions, but let's stick with those for now. Many thanks in advance.
