The Plumbright Stopcock 15x20mm is an essential plumbing component for homeowners and contractors managing outdoor and subsurface cold water systems. Its primary benefit is the ability to reliably isolate water flow for maintenance or emergency repairs, though users should note it is specifically engineered for cold water lines and should not be used in high-temperature or pressurized hot water installations.

No, this specific model is designed exclusively for cold water systems.
No, you only need standard adjustable wrenches to tighten the compression nuts.
Yes, it is designed for subsurface applications, though a valve box is recommended for access.
It allows you to connect a 15mm pipe line to a 20mm pipe line while maintaining the ability to shut off the water flow.
Generally, compression fittings rely on the olive to create the seal and do not require PTFE tape on the threads.
Ensure the pipe is cut squarely and the olive is properly seated. If the leak persists, slightly tighten the compression nut or remove and inspect the olive for damage.
Apply a small amount of plumber-approved lubricant to the stem or turn the valve back and forth slowly to work out any mineral buildup.
To install, ensure the pipes are cut squarely and are free of burrs or debris. Slide the compression nut and olive onto the pipe before inserting the pipe into the stopcock body. Tighten the nut by hand, followed by a final turn with an adjustable wrench to secure the seal. Do not overtighten, as this can damage the fitting. For subsurface installations, apply a layer of gravel around the valve box to improve drainage. Periodically turn the valve handle twice a year to ensure the internal mechanism remains free-moving and does not seize due to mineral deposits.
