Review: Great piece of kit, well worth the money! - Used this Adjustable Syphon to replace an old one installed in the 80's. Our old one stopped flushing properly for years - the membrane/film inside it had completely disintegrated, but the toilet was remarkably still flushing if you pumped the handle 2-3 times in a row. The hardest part is removing the Cistern to install it, we had to use an angle grinder to remove the rusted butterfly bolts on the coupling kit - that took about an hour just to cut through two bolts due to the tight space the toilet was in. But installation of this was super easy then after. You will need plumbers grips (which can be pretty expensive at £9-£20), to remove the old syphon and/or to install this the first time. You'll also need a new cistern coupling kit, there's strong plastic ones available at B&Q that'll not rust. I removed everything out the cistern and replaced it, for an extra £10 you can replace the water inlet and float valve meaning the cistern/toilet is pretty much brand new. Our toilet was old, so I thought it best to just do a complete refresh of the parts. Something you should consider, it could save you a lot of hassle in the long run. Now, the reduced flush is a little tricky to get your head around first. Firstly, these syohons create a suction which pulls the water up and down the bowl, it's physics, all you need is some water moving up and it creates a vacuum sucking the rest up UNTIL air is let back in and 'breaks' the syphon. This usually happens when the water level reaches below the syphon's base. But the reduced flush allows air to pass through the part where the C-link connects, meaning you save a few liters of water if you hold the handle down. Now, this caused me a problem. The water inlet was pouring water onto the C-Link part and covering it with water as soon as flushing started - creating a small puddle in the little cup next to it. This stop air getting through and ultimately caused a reduced flush to be a full flush. It's simple really, no air was let in because the water was there and so the syphon/vacuum wasn't stopped early thus flushing the full 9L. The solution was to turn the water inlet away from the syphon, and now it works great! Just something to bare in mind when installing. As far as build quality this Syphon is amazing. No I mean it really is. It works great and frankly you wonder why they weren't designed like this to begin with. So much customization for different setups and at the end of the day, my toilet works better than it has in years. Internal overflow also works as intended. Great piece of kit, well worth the money!
Review: Replacement Toilet cistern. - Having watched a number of You tube tutorials by professional Plumbers and taking their recommendation, I bought the unit which was delivered very quickly and set about the job of the syphon replacement as the original ceased working after 39 years use. The unit was very straight forward to fit (thanks to the tutorials) and the result successful. NB Check you buy the right unit for your cistern! I bought the locator ring and seal as well to be sure of no leaks plus a spare replacement diaphragm for future use( in another 39 years? ) The unit is very well made and should last /work well. Would recommend - value for money and ideal for the job. Worth watching the tutorials if you are an amateur/ DIY plumber.

### ⭐⭐⭐⭐ Easy to fit and works a treat
*by D***L on 4 November 2012*

I bought this item to replace a siphon that was no longer working. As I had to remove the siphon I decided to try out this product as it enables servicing without removal of the cistern (which I had to do to fit it). It was very easy to fit and the most difficult part was getting the corroded screw from the C-link handle. I have not had to service it but it does appear to be easily removed without cistern removal. My only slight gripe is about the price - but being able to do this and not get the plumber out easily covers this. Overall a very good product.
