- Adjustable water pressure from 0 to 50 psi

Brass Pressure Regulator for Commercial
The Watts Series 215 regulator controls water pressure in a 0 to 50 psi range. Its brass body with Buna-N seals handles a maximum inlet pressure of 300 psi and operates at temperatures up to 120 Degrees F. The unit fits 3/8 inch FNPT connections on both inlet and outlet.
Suited for New Installations Requiring Lead-Free
This regulator meets lead-free standards for potable water systems in commercial and residential settings. It is not intended for applications that require a gauge port or pressure settings above 50 psi. Builders needing a different adjustment range or a built-in gauge should select an alternative model.
Handles Standard Supply Pressure
The 0 to 50 psi adjustment covers typical residential and commercial supply requirements. The 300 psi maximum inlet rating provides substantial headroom against pressure spikes. The regulator reaches its limit when downstream demand exceeds the 3/8 inch pipe capacity or when inlet pressure surpasses the rated maximum.

Questions about this item
What size pipe and thread type must my supply line have for the 3/8 in FNPT inlet?
The regulator accepts a 3/8 in pipe with female NPT threads on the inlet side.
Will the 300 psi maximum pressure rating protect older 1/2 in copper lines downstream?
The brass body handles up to 300 psi, so it can shield legacy piping from supply surges.
How can I confirm the outlet pressure stays inside the 0 to 50 psi range after installation?
Install a gauge on the outlet and verify the reading remains between 0 and 50 psi while fixtures run.
