Gate Valves — The Old-Style Wheel Valves
Gate valves are the older type of shutoff valve — recognisable by their wheel-shaped handle. You'll find them in older properties, usually near the cold water storage tank in the loft or on the supply to the hot water cylinder.
⚙️ How they work
Unlike a ball valve that opens and closes with a quarter-turn, a gate valve works by raising or lowering a metal gate inside. Turn the wheel multiple times to open or close — typically 4–8 full turns. Clockwise to close, anti-clockwise to open.
⚠️ The problem with gate valves
Gate valves are notoriously unreliable when they haven't been operated for years. Many homeowners discover theirs won't turn only when they urgently need it.
If a plumber tells you your gate valves need replacing with ball valves — this is legitimate and worthwhile advice. Ball valves are more reliable and visually obvious when open or closed.
📍 Where to find them
Near the cold water storage tank in the loft. In the airing cupboard near the hot water cylinder. On older properties with gravity-fed heating systems.
Worth noting: If your gate valves haven't been turned in years, don't force them. A seized gate valve can snap the spindle. Ask a plumber to assess and replace with modern ball valves.
