Turbo 88 Adjustable Syphon - Adjusts from 7.5-9.5"

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!

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.

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.

If you ever had to remove one of these to change the syphon membrane after the inevitable failure you will really appreciate a flush syphon that can be serviced without removing the whole thing, particularly if your cistern is hidden and a wall was then built around it. I would rather the membrane was made out of something a bit more durable then clingfilm so it didnt disintegrate and need servicing, but barring that being able to easily remove the top part so it can be serviced is greatly appreciated. The actually installation is very straight forward. There is a dual flush capability as well. If you want a half flush then hold the flush lever down until done. If you want a full flush then just let the flush lever go once the flush starts. Overall the quality is good and it is straightforward to service the unit, just make sure you retain the small instruction sheet so you know the brand and model so you can get the correct service kit. If you don't hold on to the brand and model info then the fact that it's serviceable won't make a difference because you won't be able to get the right service kit (next lesson is how to suck eggs....). Any semi-competent DIYer can install and service the unit. Recommended.

Bought this as a replacement for an old syphon fitted in a relatively 'modern' 6L ceramic cistern. I suppose I could have just swapped the degraded flimsy plastic flappy thing but the rest of the syphon looked old and tired through years of exposure to those pesky bleach blocks. I also couldn't be bothered with the hassle of trying to guess the correct (and ording the wrong) sized fixed version. Worth a few extra quid for an adjusable version I thought. It fitted a treat actually but a day later I did have to remove it, and apply some silcone sealant to stop a leak around the down tube, and refit it. I dont think you are supposed to use silicone sealant on plastic, but hey ho. In theory i can now remove the blue syphon part without having to drain the cistern but that is dependant on there being enough space the cistern to slide out and extract the yellow pin. The only way that is achievable in our loo is to install the whole thing at a slighty jaunty angle to give the pin removal a bit more clearance clarance (Airplane! gag). This does have an internal overflow too but do make sure it's set lower than the handle hole othewise it won't work.
