The PlumbEZ Stopcock is an essential flow control valve designed for professional plumbers and experienced DIYers who need to transition between MDPE supply lines and standard copper piping. Its primary benefit is the provision of a secure, leak-free shut-off point in a plumbing system, though it requires specific compression fitting knowledge to ensure a proper seal between the two different material types.

This stopcock is primarily designed for cold water supply lines; consult professional standards before using it in high-temperature applications.
Compression fittings are designed to seal via the olive and nut; typically, no sealant is required if the pipe is cut and prepared correctly.
Yes, using a stiffener/insert inside the MDPE pipe is highly recommended to ensure the compression seal maintains its shape and integrity.
You will need a pipe cutter, a deburring tool, and two appropriate sized adjustable wrenches to tighten the compression nuts.
While the brass is durable, it is best practice to house stopcocks in an accessible valve box if installed outdoors or below ground.
Ensure the pipe is fully inserted past the compression seal and re-tighten the nut; check for debris in the fitting.
Check for mineral deposits or debris buildup inside the valve body; turn the handle back and forth several times to loosen.
To install, ensure both pipe ends are cut square and deburred to prevent damage to internal O-rings. For the 20mm MDPE side, use a pipe insert to maintain the pipe's shape under compression. Tighten the compression nuts firmly, but avoid overtightening, as this can deform the internal seals. For long-term care, occasionally turn the stopcock handle fully closed and open to prevent mineral buildup and ensure the internal mechanism remains free-moving.
