I have a slim, high cistern and I could adjust it to fit perfectly. Like all syphons of this style, it has an internal overflow. Just get the height adjustment right. 1 thing I would say, the inlet is a tight 38mm. I have 40mm pipes from B&Q and they do not fit. Had to use a reducer to plumb it it. Can't blame the product. It is clear in the description. I thought it might fit anyway. Surely poppies are a standard size? Er, no. Review: Well built and easy to fit - Had to change the internal flush system of one of our toilets. Had done it a few times before so knew what I needed. The syphon has a plastic film piece inside and its usually that that fails. Took the old one out and there was a tear in the film as I suspected which was why the flush wasn't as powerful. This is really well built and adjustable so can make it taller if needed to give the support to the lid of the unit. Can do it without any tools but having a pair of adjustable grips to tighten final plastic nuts is ideal. Works like a dream. Don't rush it and take a few pics on your phone before you take the old one out to double check if you've never done it before. And check the size of the old one as they all do vary in terms of the footprint (how much space they take up inside the cistern). ## Features - An easy to fit syphon with height adjustment from 7.5" to 9.5" - 1.5" Bottom outlet - Ideal for use as a replacement in most exposed and concealed cisterns. - Full and water saving reduced flush - Serviced in under 5 minutes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004SHDVW0 | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 86,811 in DIY & Tools ( See Top 100 in DIY & Tools ) 236 in Toilet Parts | | Colour | Blue | | Customer Reviews | 4.6 4.6 out of 5 stars (789) | | Date First Available | 17 Mar. 2011 | | Included Components | 1 x Thomas Dudley Turbo 88 2 Part 7.5 inch - 9.5 inch Adjustable Lever Flush Syphon 324395 | | Item Package Quantity | 1 | | Item Weight | 420 g | | Item model number | 324395 | | Manufacturer | Thomas Dudley | | Material | Plastic | | Measurement System | Metric | | Number of Pieces | 1 | | Part Number | 324395 | | Product Dimensions | 21 x 9 x 29 cm; 420 g | ## Images ![Thomas Dudley 324395 Turbo 88 Adjustable Syphon - Blue - Image 1](https://m.media-amazon.com/images/I/61cJhqOYdIL.jpg) ## Questions & Answers **Q: Could someone please tell me - What is the point of the height adjust. I've fitted it, not altered the height, and it seems fine.** A: It affects the over flow level ie how high the water level is in the cistern .untill it overflows in to the bowl **Q: My cistern is a dual flush jobbie with 2 buttons. Will this syphon do 'the job', or do I need another type of syphon?** A: I don't think so, as the design relies on two different operation of a single flush handle. I doubt if this can be adapted for a two-button flush. **Q: Can I adjust the quick flush** A: As far as I am aware there is not any adjustment to the flushing system, other than press and hold the flush handle down for a part flush or press and immediate release for a full flush **Q: Can this be used to replace the dudley cacsade flush** A: Bear in mind I am not a plumber ,or diy person.I have looked at pictures and think it may be same of very similar.it's really easy to fit,just need to take your time making seals secure.they screw on.if I can do it ,anyone can.good luck. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality syphon *by R***B on 25 January 2022* I found this item to be very good quality.

Over a period of time the dual flush feature has failed and seams not to be able to fix / repare. something to do with an odd size large black rubber wisher that should be a few pence to replace if I could find a supplier. It apears like most modern things, designed to wear out over someting tiny and replace the whole item. Update, 2 years on, I have worked out a fix to restore the dual flush. two images attached edited extracts from on of Dudleys manuals with notes added. 1. isolate water supply and flush emply cistern 2. Carfully remove the syphon part of the machanisum 3. Carfully dismantle the diaphragm. 4.Clean the two washers, 1 plastic and 1 rubber and dry. 5. Three or four small drops of contact adhesive on the e flat side of the plastic washer and bring the two washers together, leave to cure as adhesive instructions. 6. Reassemble with replacement diaphragm if required and refit unit. 7. Turn on water and test. Our installation now works agin like new. One star knocked off for poor design in the first place. --- ## 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.tn/products/63754356-thomas-dudley-324395-turbo-88-adjustable-syphon-blue](https://www.desertcart.tn/products/63754356-thomas-dudley-324395-turbo-88-adjustable-syphon-blue) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-15*
