Review: Does as it says! - Works perfectly ! Very easy to fit and does the job! Now it flushes with just a feather touch compared to before where you had to flush at least 7 times in order to create vaccumm! Very pleased with the purchase.
Review: The best syphon I have ever known - I have had so much problems with the new generation of flush syphons that became fed up of regularly fitting replacements. I eventually purchased the first Fluidmaster Pro-ultra Universal Dual Flush Syphon from a local shop a few years ago and was pleasantly surprised. As this is the best flush syphon I have ever known, I bought a second one and fitted it in a second toilet. Delivery was quick and it was securely packaged. Just gently depress once and all the water right to the bottom of the cistern flushes into the pan. No need to flush a second time as with other syphons. There's ample adjustment to fit most cisterns and fitting it is simple. I am not a plumber but found it easy to install. It's excellent value for money. I have now purchased a further 3 to fit in my other house. I highly recommend.

## Features

- Compact Toilet Syphon with Universal Fit – The space-saving toilet syphon design fits virtually all 1½″ lever-operated cisterns, making it an ideal replacement for existing installations and retrofit applications.

I'd never done one of these before. Very good quality and was surprised how many things could be adjusted on this to get the water level and flush feel just right. Highly recommend to anyone replacing or installing new toilet guts.
