VIEGA plumbing bypass fitting 15 mm — full bypass (model 508515)

The VIEGA plumbing bypass fitting 15 mm — full bypass (model 508515) is a compact plumbing component designed to provide an alternative flow path in water installations with a 15 mm connection diameter. Intended for use in residential and commercial systems, this full bypass fitting enables continued water flow during maintenance, valve replacement or rerouting of piping. The design supports temporary or permanent bypass needs where uninterrupted service is required.

Advantages

This full bypass fitting offers straightforward integration into existing 15 mm plumbing runs and is constructed to meet the practical demands of service work. Its 15 mm connection diameter ensures compatibility with standard small-diameter domestic and light-commercial piping. The fitting simplifies maintenance operations by allowing isolation of a section while maintaining service to the rest of the circuit, reducing downtime during repairs or modifications.

Suitable for

• Creating a temporary bypass during valve replacement or repair
• Rerouting flow around a section under maintenance
• Maintaining water supply in residential or light commercial plumbing while work is performed
• Use in service loops, repair patches and retrofit installations

Key specifications

• Connection diameter: 15 mm
• Type: full bypass fitting for plumbing systems
• Application: water installations in residential and commercial buildings
• Function: provides alternate flow path for maintenance or rerouting

How to use

Install the bypass fitting into a 15 mm supply line according to standard plumbing practice, ensuring the system is depressurized before work begins. Fitters should use appropriate joining methods compatible with the pipe material and the fitting, follow manufacturer torque and sealing guidance, and verify that all connections are leak-free after installation. Operate valves to direct flow through the bypass when isolating the work section, and return the flow to the original route once maintenance or replacement is complete.

Usage recommendations

Use the bypass fitting with 15 mm pipes that match the fitting's connection type and material compatibility. Ensure routine inspection for leaks after initial installation and after any change in system pressure. For permanent installations, verify compatibility with the plumbing system standards and local codes. When in doubt, consult a qualified plumber to determine the correct joining method and safe installation practice.
