Rated 5 out of 5 by from TD duo flush Easy to fit siphon that works well. The description given on the website ensured that it was the correct item, thank goodness as I purchased it for the husband to fit! So you can see I couldn't get it wrong!! After finding a youtube clip within an hour this diy opposer (hubby) fitted it with ease!! Happy wife! Duo flush was a bonus!

Rated 5 out of 5 by from Great dual flush Device works well with reduced water consumption and is very easy to install. It is a fixed height siphon with the ability to be adjusted to deliver 6, 7 or 9 litres as required. Beware Screwfix instructions download. It is not for this device ! You will also need the old or a replacement large siphon to WC seal doughnut washer (for example Screwfix code 39353) as this is not supplied. Parts supplied seems to be geared towards a high cistern arrangement.

Rated 5 out of 5 by from Quality item Easy to fix and uses less water than previously which is a good thing. Would definitely recommend this to anyone who has a bit of diy experience because the instructions are good.

Rated 4 out of 5 by from Dudley Siphon I replaced a much cheaper siphon, which had failed, with this one. Whilst this product is more expensive than the model it replaced it is serviceable. I hope this will mean I won't have to remove the toilet cistern in the future.

This says it is 9" 205mm but 9" = 228mm and 8" = 205mm

Asked by: Hogfather
Good Afternoon, It looks like there is a typo mistake on the website. 9" should be 229mm and 8" is 203mm Kindest Regards Thomas Dudley Sales Team

Is this suitable for a toilet water tank with a 49mm discharge hole

Asked by: Cheshirewarrier

Can this siphon be used with a high level cistern. What is the best siphon mechanism for a high level cistern? Thanks

Asked by: 184869

How do I know if I need 8inch, 9inch or 237mm???

Asked by: Se88
Good Morning, Thank you for your enquiry, you would need to measure your water line in your cistern. For example, if your water line is measuring 7" you would need to add an extra inch on top of the height you require for the internal overflow to work, therefore you would need to purchase an 8" syphon. I hope this information help. Kindest Regards Thomas Dudley Sales Team
