Saw this at a great price and said I'd try it. It arrived the next day (I have Prime) and I went about installing it. All was going well until I came to the coupling plate (the silver bit that connects the cistern to the toilet) because this kit does not include the plate, and the one that is used on standard Irish toilets is too small. I COULD NOT get a plate to fit over the new fitting in any local plumbing supplier (as it is a EURO size) so I had to improve and make the hole on the old one a bit bigger with the help of the hacksaw. Once I got this sorted, it was a breeze. It works really well but perhaps the button push is a tad on the hard side to push. All in all, it's good but be aware of the dreaded coupling problem. ## Frequently Bought Together - Ibergrif M20521 Toilet Cistern Bottom Side Fill Valve Adjustable Telescopic Urinal Flush Valves Parts M13-17 (3/8") Plastic & Brass Multi Color - Close Coupling Kit for WC Toilet Pan Cistern Doughnut Fixings Plate Donut - SPARES2GO Toilet Cistern Seal Kit 100mm M6 Bolt Through 1.5" Rubber Dome 2" Foam Washer Set --- ## 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.vu/products/517476916-m20521-toilet-cistern-bottom-side-fill-valve-adjustable-telescopic-urinal](https://www.desertcart.vu/products/517476916-m20521-toilet-cistern-bottom-side-fill-valve-adjustable-telescopic-urinal) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-03*
