Scald Protection Valve 1/2 In NPSM

This Powers Scald Stop valve is a temperature shut-off device designed for 1/2 inch NPSM shower connections. It automatically stops water flow when temperatures exceed safe limits, reducing scald risk in healthcare facilities, hotels, schools and residences. The brass body provides durability and corrosion resistance for long service life in commercial and domestic plumbing systems. Installation fits standard two-port configurations with compact 1 by 1 3/4 by 1 inch dimensions.

Suitable For Safety-Critical Showers Not CEC

This valve suits specifiers and installers needing point-of-use scald protection where CEC compliance is not required. It serves hospitals, care homes, hotels, schools and private residences with 1/2 inch NPSM shower arms. Projects requiring CEC-listed devices or non-NPSM thread types such as BSP or compression fittings must select alternative approved hardware. The non-CEC status limits use in jurisdictions mandating that certification.

Connection Size 1/2 Inch NPSM Thread

The single specification determining fit is the 1/2 inch NPSM connection thread on both ports. Verify that the shower arm and outlet share this exact thread standard before ordering. Mismatched threads will prevent sealing and compromise the temperature shut-off function. No adapters are included, so existing plumbing must already present male NPSM ends for direct installation.

Questions about this item

What size and thread type must the supply pipe have for the 1/2 in NPSM connection?

The valve connects to a 1/2 inch NPSM threaded pipe, so the supply must match that size and straight mechanical thread standard.

Will the brass valve body resist corrosion when installed in an older galvanised steel plumbing system?

Brass construction provides good corrosion resistance, but direct contact with dissimilar metals such as galvanised steel may require a dielectric union to prevent galvanic action.

How can I verify the temperature shut-off activates at the correct point after installation?

Run hot water through the valve and confirm flow stops when the outlet temperature reaches the device’s internal limit; the shut-off is automatic and non-adjustable.
