External Stopcock Installation

What external stopcock installation covers

A properly fitted external stopcock (isolation valve) provides a clear, accessible shut-off point and helps protect outdoor pipework. The service typically includes:

• Assessing the existing incoming supply and the best location for safe, convenient access
• Installing a new external stopcock, or replacing a seized or leaking valve
• Renewing short sections of exposed pipework and fittings if required for a sound connection
• Securing pipework and ensuring correct valve orientation and operation
• Pressure and leak testing after installation
• Weather protection measures, such as insulation and positioning to reduce frost risk

When this service is most useful

External stopcocks are often requested when:

• You cannot easily access or operate the internal stop tap
• The current valve is stiff, seized, leaking, or unreliable
• You want a clear shut-off point for a garden supply, outside tap, or outbuilding feed
• You are a landlord improving safety and maintainability between tenancies
• You have experienced freezing or damage to exposed external pipework

How the work is carried out

The work is planned to minimise disruption and leave the valve easy to locate and use.

1. A short survey confirms pipe type, routing, and isolation options.
2. The water supply is turned off and the line is drained down where needed.
3. The valve is fitted with appropriate connectors and supports for the pipe material.
4. The system is refilled, tested under pressure, and checked for smooth operation.
5. Insulation and finishing touches are added to reduce weather-related issues.

Aftercare and ongoing protection

You will be shown how to operate the new stopcock and what to do in an emergency. If the valve is in an exposed position, simple seasonal checks and insulation upkeep help reduce the chance of freezing and future leaks.
