The Plumbright 28mm Stopcock (S20228) is an essential plumbing component designed for professional plumbers and DIY enthusiasts needing a reliable way to isolate water supply in residential and commercial piping systems. Its primary benefit is providing a robust, leak-free shut-off mechanism that ensures long-term durability and peace of mind during maintenance. The main caveat to consider is that while it is designed for ease of use, it requires proper compression fitting skills to ensure a watertight seal, and users should ensure they are working with the correct 28mm pipe size before installation.

Yes, it is suitable for use in standard water-based central heating systems using 28mm piping.
No, this is a compression fitting stopcock and does not require soldering.
No, this product is designed strictly for water flow control and is not rated for gas.
The body is typically made from high-quality brass or plated metal, designed for durability in plumbing systems.
Yes, the stopcock can be installed in any orientation provided there is enough space to operate the handle.
Typically, compression fittings come with the necessary olives and nuts included.
Gently tighten the compression nut another quarter turn. Do not overtighten, as this may strip the threads.
Ensure the valve handle has been turned fully to the off position. If it still leaks, there may be debris in the valve seat requiring a replacement unit.
Verify that the pipe end is perfectly round and free of burrs or paint residue.
To install, first ensure the water supply is turned off upstream. Cut your 28mm pipe cleanly and remove any burrs from the cut edge to prevent damage to the internal O-rings. Slide the compression nut and olive onto the pipe, then insert the pipe into the stopcock body. Tighten the nut by hand first, then use an adjustable wrench to turn it a further half to three-quarters of a turn to compress the olive onto the pipe. Avoid overtightening, as this can deform the olive or damage the thread. Periodically check for any signs of dampness around the connection points, especially after the first 24 hours of operation.
