Happy now !!! 🐶 ### ⭐⭐⭐⭐⭐ Excellent quality, excellent value *by H***Y on 26 November 2020* Bought to be used in a shower. It is genuinely full bore with a good action. The metal knob is both strong and looks good. Item feels and looks like a quality item, excellent value for the price. UK delivery time was quicker than the estimated delivery date. ### ⭐⭐⭐⭐⭐ Just the job *by C***S on 21 September 2025* Fitted a like for like shower in after replacing an old isolation valve, first thing I found was the shower water pressure low, so bought this large bore isolation valve for easy operation with fitted level. And the water pressure to the shower was much much better, all you've got to watch is it's slightly longer if your swapping out an existing old isolation valve. But I would buy this unit again. ## Frequently Bought Together - Large Bore 15mm Isolation Valve with Butterfly Handle - 2 x 15mm Isolation Valves Reeds WRAS Approved --- ## 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.pt/products/58996513-large-bore-15mm-isolation-valve-with-butterfly-handle](https://www.desertcart.pt/products/58996513-large-bore-15mm-isolation-valve-with-butterfly-handle) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-17*
