Pressure Regulator 10-25 psi
The Watts B1156F pressure regulator controls water pressure between 10 and 25 psi for residential and commercial plumbing systems. It features a bronze body with 1/2 inch MNPT connections and a Buna-N seal. The unit handles a maximum pressure of 100 psi and temperatures up to 212 degrees F.
Replaces Fixed-Rate Valves
This adjustable regulator replaces non-adjustable pressure-reducing valves when supply pressure fluctuates or when fixtures require a specific lower pressure range. The jump is worth it when appliances or fittings are rated below the incoming main pressure and need consistent protection within the 10 to 25 psi window.
Fits 1/2 Inch Plumbing Lines
The regulator installs directly into 1/2 inch threaded pipework using its male NPT inlet and outlet. Its compact 3 1/2 inch length allows placement in tight mechanical rooms or utility cabinets. The bronze construction resists corrosion in potable water systems, freeing up maintenance intervals compared to lesser materials.

Questions about this item
Will the 1/2 in MNPT connections on this Watts B1156F regulator match my existing piping?
The regulator uses 1/2 in male NPT threads on both inlet and outlet, so it threads directly into matching female fittings without adapters.
What is the correct orientation when installing the Watts 1156F regulator, and which step is often missed?
Install with the flow arrow pointing downstream; the step most often missed is flushing the line before threading the regulator in to avoid debris on the Buna-N seat.
How often should the internal Buna-N seals be checked or replaced on the Watts B1156F?
Inspect the Buna-N seals annually and replace them if you see pressure creep above the 10 to 25 psi set range or any external weeping at the body joints.
