The Plumbright Stopcock (S30328) is an essential component for homeowners and professional plumbers looking to reliably manage domestic water supply lines. This DZR (Dezincification Resistant) fitting provides a durable method for isolating water flow during repairs or emergencies, featuring a precise 25mm to 22mm transition. While it offers robust construction and a secure seal, it requires careful installation to ensure the compression joints are leak-free and properly aligned with existing pipework.

Yes, the materials used are suitable for standard domestic water supply systems.
No, compression fittings create a seal using the brass olive; PTFE tape is generally not required and can sometimes interfere with the seal.
Yes, this stopcock can be installed in any orientation that allows for easy access to the operating handle.
DZR stands for Dezincification Resistant; it is a specialized brass alloy designed to resist corrosion in water systems.
It is highly recommended to use new olives whenever you disconnect and reconnect a compression fitting to ensure a leak-proof seal.
Gently tighten the compression nut another quarter turn. Do not force it if resistance is high.
Ensure the valve is not under tension from misaligned pipes; apply a small amount of silicone-based lubricant to the stem.
Check if the internal washer has been damaged by debris; flush the system or replace the internal valve assembly if necessary.
To install, ensure the pipes are cut squarely and deburred properly to prevent damage to the internal seals. Slide the compression nut and olive onto the pipe before inserting the pipe into the stopcock body. Tighten the nut by hand first, then use a suitable wrench to tighten approximately one full turn; do not overtighten, as this can deform the olive. For maintenance, periodically operate the handle to prevent lime scale buildup. If the valve becomes stiff over time, a light application of plumbing-grade silicone grease to the stem can help maintain smooth operation. Always ensure the system is drained before beginning installation to avoid water damage.
