Frequently Asked Questions

AI
Many of these fittings, such as push-fit connectors and compression valves, are designed for DIY installation. However, if you are unfamiliar with isolating your water supply or working with copper piping, consulting a professional is safer to avoid leaks.
Compression fittings use a nut and ring to grip the pipe, often requiring a spanner for a tight seal. Push-fit connectors rely on an internal gripping mechanism and O-ring, allowing for tool-free installation, though they are sometimes more expensive.
Check the thread size, typically 3/4 inch BSP for most UK washing machines and dishwashers. Always verify if you need a straight valve or a Y-piece splitter if you are connecting multiple appliances to one water feed.
