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: Is it worth the extra few quid? - Before I answer that, here is what happened to me, my toilet siphon stopped working, so off I pooped..er I mean popped down the local hardware shop, and brought a cheap as chips replacement. After giving the toilet a extra intense cleaning, I mean who wants to work that close to a toilet, c'mon man yeech. I replaced the siphon, and 14 months later it quit on me again. Now I did not enjoy changing that thing out at all, it was an icky task, and I did hit the odd speed bump. So this time I researched it before racing off for another El cheapo. Seems the the water level in your tank is important. Mine was 8" inches ( yeah I know *blushes* ) it seems that El cheapo was a 9" one, did this lead to early failure I dont know maybe, maybe not. So I looked at getting the right size siphon, and came across the Turbo 88 (yeah even I think the names a little over board) but it did have 3 great features that I liked. Number 1 it is adjustable to many water levels. ( I since found out that using the correct height stops dribbling flushes, who knew ) and number 2 you can replace the siphon part without removing the whole thing. ( still turn the water off first OK ). And the Turbo 88 ( gotta laugh every time I say that ) has the best feature ever, the stick a finger up to the Europrats who came up with the Short press = long flush and Long press = short flush crap ( sorry had to get that in this review somewhere, it the Turbo 88 ( giggle ) has an single flush option. One press and it flushes. Good flush too. Ok We're now seven years in, (yes 7) and still no problems. So the opening question, is it worth the extra money?

Definitely a yes from me Updated: March 2018 ### ⭐⭐⭐⭐ Superb product and excellent innovation. *by A***I on 1 December 2018* Brilliant in the fact that it feels well made and the idea of being able to separate the body of the flush whilst keeping the pipe connected should make it quite easy to maintain in the long term. Instruction could be written in an easier way to understand especially for a novice like me who has never looked into a cistern before in my life but youtube videos and online forums have helped me navigate my way through installation process. Also the body of the flush was a bit bigger than the old one and would not fit without lifting the body level higher up (which the flexibility and adjustability of this system has enabled me to do) and also trimming some of the plastic ridging on the side of the body to allow it to snuggly fit into the cistern. Took me a couple of hours at the end (apart from time spent looking how to do things up online) but worked perfectly at the end and very happy with the result. ## Frequently Bought Together - Turbo 88 Adjustable Syphon - Adjusts from 7.5-9.5" - Close Coupling Kit for WC Toilet Pan Cistern Doughnut Fixings Plate Donut - Merriway BH00126 Toilet Cistern Handle Fitting Chromed Metal -1 Pcs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/49930951-turbo-88-adjustable-syphon-adjusts-from-7-5-9-5](https://www.desertcart.be/products/49930951-turbo-88-adjustable-syphon-adjusts-from-7-5-9-5) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-17*
