Gate Valve
Also known as: wheel-head valve, tank valve
An older style valve controlled by multiple turns of a round wheel handle. Common on low-pressure gravity-fed pipework near water tanks and cylinders.
Near cold water storage tanks in the loft and on supplies to hot water cylinders.
Round metal wheel handle — requires several full turns to open or close, unlike a quarter-turn ball valve. Available in 22 mm or 28 mm.

Always turn off the water supply before replacing any part. If in doubt, consult a qualified plumber. Gas components must only be worked on by a Gas Safe registered engineer. Unvented (pressurised) hot water systems must be worked on by a G3-qualified engineer. Prices shown are indicative — check retailers for current pricing.
