Review: Just What You Need - This is a well-manufactured product and is easy to fit, by way of a straight replacement for a standard part 1 ball-cock assembly. Mine was dripping despite my fitting a new rubber pad, so it was the valve seating that had gone. You can buy a repair kit and dismantle the old valve in-situ and fit a new valve seating, seal and rubber pad but that assumes that your old retaining nut hasn’t seized; it also assumes that you have easy access to it! My advice is to buy a new assembly and just uncouple the water connector on the outside of the tank. You can then easily remove the nylon nuts that hold the ball-cock assembly and fit the new one. You could service the old one very easily, using a repair kit, if you want to have a ball-cock up and ready for fitting in a few years’ time; otherwise just chuck the old one away. Finally I should say that I don’t understand why some reviewers have said that this valve is noisier than average. I don’t think it is; anyway, if it is for your header-tank then that should have a lid and it will normally be in your loft. I can’t hear mine at all! Review: Does the Job. - After a new water/heating system was installed our loo water changed from very low pressure from tank to VERY high pressure from the main and the existing valve gave up trying to stop it. This did the job perfectly in controlling the water but a couple of minuses. I needed to bend the arm vey slightly. A common requirement when fitting these. A very small sideways pressure on the ball resulted in the thread shearing. Maybe I should have tried to hold the rod, not the ball, but it's not the first time I have had to do this and never had a problem before. Fortunately I was able to get the thread stud out of the ball and there was just enough thread left to refit. Second problem was that with our high pressure this was very noisy. Enough to wake you up at night if partner used the loo. It would have been nice if it had the provision of a down pipe to take the water to the bottom of the cistern but we got in the habit of shutting the loo door before flushing. I talk in the past tense as we have now fitted a complete new bathroom/toilet with a new loo and cistern. The valve on that fills up just as fast but is very quiet. If you remember to take care bending the arm and can't find an option with a filler downpipe this is a good product which does the job required. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00Y3PMS9O | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 418,078 in DIY & Tools ( See Top 100 in DIY & Tools ) 186 in Float Valves 844 in Toilet Parts 13,449 in Bathroom Fixtures | | Customer Reviews | 4.4 4.4 out of 5 stars (280) | | Date First Available | 4 July 2011 | | Item Package Quantity | 1 | | Item Weight | 180 g | | Item model number | VDTAZ012 | | Manufacturer | Choice DIY | | Material | Brass | | Package Dimensions | 32.4 x 6.6 x 1.6 cm; 179.99 g | | Part Number | 5052436072316 | | Size | 1/2 inch | ## Product Details - **Brand:** Choice DIY - **Exterior finish:** Brass - **Inlet connection type:** Flare - **Manufacturer:** Choice DIY - **Material:** Brass - **Number of ports:** 2 - **UPC:** 798256132193 ## Images ![1/2" Part 1 High Pressure Brass Float Valve - Image 1](https://m.media-amazon.com/images/I/21eb3KmUXaL.jpg) ## Questions & Answers **Q: what's the difference between a part one and part 2 ballcock pls** A: Hello - a part 2 valve is designed to have a large enough gap between the outlet and the surface of the water in the tank to prevent the risk of water being able to be drawn back into the water supply. This to comply with water regulations. Part 1 valves do not have such a gap. Hope that makes sense **Q: Is this a standard replacement arm for a traditional standard cistern please ? Thanks.** A: All I can say is, if you have a cold water tank somewhere in the house that feeds your hot water tank with a 1/2" thread on the side, and you need to stop the cold water tank from overflowing, then this should solve your problem. you will, obviously, need a ball float that are widely available, B&Q, Wickes, and even Amazon of course. **Q: is this a quieter type of ball cock system, one where water noise on exit is less is less and** A: No! This is the conventional ball cock but you can get cistern valves with a plastic pipe ond the pipe outlet is under the water line so makes very little noise. **Q: Part no vdtaz012 is32.4 the length of the flout arm ( 1/2 ins long arm float valve)** A: Yes! The float arm is approximately 30cm/12 inches long ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just What You Need *by K***N on 8 January 2021* This is a well-manufactured product and is easy to fit, by way of a straight replacement for a standard part 1 ball-cock assembly.
