Tapped Blank 4"
Product Specifications
Product Name: Tapped Blank 4"
Main Size: 4"
Product Type: Tapped blank / blanking plate
Application: Fire protection pipework, riser systems, hydrant systems, sprinkler systems, and mechanical water services
Connection Use: Designed to blank off a 4" pipework connection
Tapped Outlet Use: Commonly used for an air release valve, drain valve, test point, or compatible threaded accessory
Installation Type: Pipework blanking and valve take-off fitting
Product Use and Protection
It is often installed at strategic points in a system where trapped air needs to be released or where water needs to be drained from the pipework during testing, servicing, or maintenance.
Typical uses include: Air release valve connection and drain valve connection. System venting point. This makes the tapped blank a practical fitting for both installation and long-term maintenance of fire protection and water pipework systems.
UK Regulations and Standards for Fire Protection Pipework
In the UK, fire protection pipework should be correctly designed, installed, inspected, and maintained by competent professionals.
The Law: The Regulatory Reform (Fire Safety) Order 2005 makes the building’s “Responsible Person” legally accountable for maintaining fire safety systems.
System Design: Fire protection pipework and associated fittings should be selected in accordance with the project specification, fire strategy, system pressure requirements, and relevant British Standards.
Compatibility: Before installation, the tapped blank should be checked for compatibility with the pipe size, connection type, system pressure, gasket or sealing method, and the air release valve, drain valve, plug, or accessory being fitted.
Access and Maintenance: Any tapped blank used for an air release valve, drain valve, testing point, or monitoring point should remain accessible for inspection and maintenance.
Installation Guidance
The Tapped Blank 4" should be installed by a competent person as part of a suitable pipework or fire protection system.
Before installation, the installer should confirm the correct size, tapping size, thread compatibility, pressure suitability, and sealing method.
The fitting should be correctly aligned, securely fixed, and properly sealed to prevent leaks. If used for an air release valve, it should be positioned where air can collect and be released effectively. If used for a drain valve, it should be positioned where water can be safely drained from the system.
Maintenance Requirements
The pipework system, including the 4" tapped blank, should be inspected and maintained by a competent person.
Visual Inspection: Check the tapped blank, valve connection, threaded outlet, plug or accessory, seals, and surrounding pipework for signs of leaks, corrosion, damage, movement, or tampering.
Air Release Valve Check: Where fitted, ensure the air release valve remains accessible, operational, and free from obstruction.
Drain Valve Check: Where fitted, ensure the drain valve remains accessible, securely closed when not in use, and free from leaks.
ystem Testing: Where installed on a fire protection system, the fitting should be included in the relevant pressure testing and maintenance schedule.
A full logbook should be kept for inspections, tests, repairs, and remedial works where required.
This product should be checked for suitability before installation, including size, tapping size, thread type, pressure rating, material compatibility, and intended system use.
Please check all products before signing for the materials. We cannot be held responsible for goods after they have been signed for.
Due to the specialist nature of fire protection and pipework fittings, this product may not always be available on a standard next working day service. Lead time will be advised where applicable.
