Box Contains Inlet valve; nut; seal; washer; instruction Review: DOES THE JOB INTENDED - Bought this as a replacement for the same part which had been broken. This one had a metal threaded lower part which was an improvement. Now fitted and does the job intended. Plumbing supply merchants online wanted a hefty postage charge, whereas desertcart Prime is free - no brainer! Happy with my purchase. Review: Good quality - Bought this to replace a fairly decent one that had a plastic fitting. It had started to leak (washer had deformed slightly, I think) and in removing it the thread on the plastic fitting got ripped to pieces. Decided to replace it with one with a brass fitting. This one was a good price, but worked very well. It's quiet and simple. ## Features - WRAS approved - Telescopic height adjustment - Suitable for high and low pressure - Operating pressure from 0.1 to 10 bar - Quiet fill, with hydraulic closure ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00M2VW7HO | | Best Sellers Rank | 38,618 in DIY & Tools ( See Top 100 in DIY & Tools ) 142 in Toilet Parts | | Brand | SIAMP | | Customer Reviews | 4.5 out of 5 stars 1,047 Reviews | | Exterior Finish | Brass,Plastic | | Exterior finish | Brass , Plastic | | Global Trade Identification Number | 03247230069521 | | Included Components | Inlet valve; nut; seal; washer; instruction | | Inlet Connection Size | 1/2" Inches | | Inlet Connection Type | Brass Thread | | Inlet connection size | 1/2" Inches | | Inlet connection type | Brass Thread | | Item Dimensions | 8.5 x 6 x 33 centimetres | | Item Type Name | 99T ½”Brass LP Inlet Valve 30992110 | | Item Weight | 249 g | | Item dimensions L x W x H | 8.5 x 6 x 33 centimetres | | Manufacturer | SIAMP | | Manufacturer Warranty Description | 10 year. | | Material | Brass , Plastic | | Maximum Pressure | 10 Bars | | Model Number | 30992110 | | Number of Pieces | 1 | | Number of Ports | 1 | | Outlet Connection Size | 2 Inches | | Outlet Connection Type | BSP | | Part Number | 30992110 | | Specification Met | WRAS | | Thread Size | 1/2 inch | | Thread Type | Thread | | Unit Count | 1.0 count | | Valve Type | bottom inlet valve | ## Product Details - **Brand:** SIAMP - **Exterior finish:** Brass,Plastic - **Inlet connection size:** 1/2" Inches - **Inlet connection type:** Brass Thread - **Item dimensions L x W x H:** 8.5 x 6 x 33 centimetres - **Material:** Brass, Plastic - **Maximum operating pressure:** 10 Bars - **Number of ports:** 1 - **Outlet connection size:** 2 Inches - **Outlet connection type:** BSP ## Images ![SIAMP 30992110 1/2" BSP 99T Brass Thread Bottom Inlet Valve - White - Image 1](https://m.media-amazon.com/images/I/61xUr1TAUML.jpg) ![SIAMP 30992110 1/2" BSP 99T Brass Thread Bottom Inlet Valve - White - Image 2](https://m.media-amazon.com/images/I/61gR9MCxZoL.jpg) ![SIAMP 30992110 1/2" BSP 99T Brass Thread Bottom Inlet Valve - White - Image 3](https://m.media-amazon.com/images/I/81c8EiVZbJL.jpg) ![SIAMP 30992110 1/2" BSP 99T Brass Thread Bottom Inlet Valve - White - Image 4](https://m.media-amazon.com/images/I/71ZBbQXZHOL.jpg) ![SIAMP 30992110 1/2" BSP 99T Brass Thread Bottom Inlet Valve - White - Image 5](https://m.media-amazon.com/images/I/51zB5gpTXLL.jpg) ## Questions & Answers **Q: i have one of these & the float does not stop it filling, but somehow it stops when it gets to the overflow. Any ideas as to what's wrong? TIA** A: Sounds like you need to set the float level. **Q: Are there instructions supplied?** A: Yes, comprehensive instructions supplied. Came with short cable assy and so had to use the original one, wasn't too hard to do. **Q: Does this need to attach to something downstream of it? There's what looks like a place to attach some kind of hose that goes out and into the cistern** A: Apart from the inlet at the base (threaded brass part) which is fed from the mains pipe there is no other attachment required. The cistern fills from water coming out the top of the unit until the level in the cistern is reached and cut off by the float valve... **Q: Just fitted this and it doesn’t stop filling, i have set the float level but doesn’t shut off the valve, any ideas? Thanks** A: Lift the float manually, if it shuts off then you’re doing something wrong with the float setting. If it doesn’t shut off when you lift it manually then you have a faulty unit ## Customer Reviews ### ⭐⭐⭐⭐⭐ DOES THE JOB INTENDED *by R***E on 8 March 2026* Bought this as a replacement for the same part which had been broken.
