Equal Standard Tee
Product Specifications
Product Name: Dry Riser Equal Standard Tee 4″ Grooved
Product Type: Equal tee / grooved pipe fitting
Main Size: 4″
Branch Size: 4″
Connection Type: Grooved
Application: Dry riser pipework and fire protection systems
Function: Creates a branch or directional split in dry riser pipework
Use: Suitable for creating pipework drops, branches, or multiple flow directions
Product Use and Protection
The Dry Riser Equal Tee 4″ Grooved is typically used where dry riser pipework needs to be split into multiple directions or where a branch connection is required without reducing the pipe size.
Because all three outlets are the same size, the fitting allows for consistent pipework sizing across the main run and branch connection. This makes it useful for maintaining balanced flow through the system and supporting efficient dry riser layout design.
This product is commonly used in dry riser systems, fire protection pipework, vertical riser pipework..
UK Regulations and Standards for Dry Riser Pipework
In the UK, dry riser systems must be correctly designed, installed, inspected, and maintained so they are ready for Fire Brigade use in an emergency.
The Law: The Regulatory Reform (Fire Safety) Order 2005 makes the building’s “Responsible Person” legally accountable for maintaining fire safety systems.
Building Regulations: Approved Document B requires dry risers in buildings where the top floor is between 18m and 50m from ground level. Buildings over 50m generally require wet risers.
The Standard: BS 9990:2015 is the main code of practice covering the design, installation, testing, and maintenance of dry riser systems.
Compatibility: Before installation, the equal tee should be checked for compatibility with the pipe size, groove profile, coupling type, gasket type, system pressure, pipe material, and intended dry riser application.
Installation Guidance
Before installation, the installer should confirm the correct pipe size, groove dimensions, coupling compatibility, gasket suitability, and system pressure requirements. The pipe ends should be clean, correctly grooved, and aligned before the fitting is installed. Compatible grooved couplings and gaskets should be used to secure the tee to the pipework. The pipework should be properly supported so the tee and connected pipe runs are not exposed to unnecessary stress, movement, or misalignment.
Maintenance Requirements
Six-Monthly Visual Inspection: Check the tee, grooved couplings, bolts, nuts, gasket areas, and surrounding pipework for signs of leaks, corrosion, damage, movement, tampering, or misalignment.
Annual Wet Pressure Test: Once every 12 months, the dry riser system should be filled with water and pressure tested to ensure it is watertight and capable of withstanding operational pressures.
A full logbook should be kept for all inspections, tests, repairs, and remedial works where required.
This product should be checked for suitability before installation, including pipe size, groove type, gasket material, pressure rating, and intended dry riser 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 dry riser fittings, this product may not always be available on a standard next working day service. Lead time will be advised where applicable.
