Common Questions — Stopcock Repair in Harrow

How do I turn off my water in Harrow if the stopcock is seized?

If your internal stopcock is seized in a Harrow property, the water can usually be isolated at the external stopcock on the pavement (requires a stopcock key) or at the water meter box. Call us — we carry stopcock keys and can isolate within minutes of arrival.

Can you replace a seized stopcock without cutting off the whole supply in Harrow?

We use the external stopcock or meter to isolate the supply to your Harrow property, then replace the internal stopcock. The whole process typically takes under an hour and supply is restored before we leave.

My stopcock is leaking in Harrow. Is that an emergency?

A leaking stopcock spindle gland in a Harrow property is usually a slow drip that can wait for a scheduled visit. If the stopcock body is leaking or the valve won't close, that's more urgent — call us immediately so we can isolate and repair before it worsens.
