The float is the big plastic piece and its position can be adjusted. This inlet valve would normally replace an inlet valve with ball float, given that the basin dimensions can accommodate it. **Q: Is the inlet 1/2"bsp (21mm) or is it 3/8" bsp (16.67mm)?** A: It says on the inlet float valve it`s 1/2in.. 15mm plastic. **Q: What’s the outside diameter of the bottom screw thread part?** A: I`d say a Quarter of an inch. You will easy see when you take the old one off. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly What I Needed *by C***S on 28 April 2026* This was just a perfect replacement to replace my original Siamp silient fill inlet valve very easy to install the only noise is the original flush , no power needed just spanners ,and easy to adjust the fill height of cistern hope it lasts as long as my last one. ### ⭐⭐⭐⭐⭐ Works as described 👌 *by M***H on 18 May 2026* Cheap option for fixing your toilet.
