## Summary description

Sourcing PRESSURE REDUCER 3/4 (model 91271AE05) is a pressure-reducing valve designed for water supply systems with a 3/4" connection. It lowers and stabilizes incoming water pressure to protect plumbing, appliances and fixtures. Typical use includes residential and light commercial installations to prevent overpressure, reduce pipe stress and improve system reliability.

## Long description

Sourcing PRESSURE REDUCER 3/4" model 91271AE05 is a pressure-reducing valve designed for water supply systems with brass inlet and outlet connections. The device lowers and stabilizes incoming mains pressure to a safer, preset level, protecting domestic plumbing, fixtures and appliances from overpressure and reducing stress on pipes and fittings. It is intended for installation on cold water lines where stable pressure is required for reliable operation of taps, toilets, washing machines and other water-using equipment.
Advantages
The copper-alloy (brass) inlet and outlet provide corrosion resistance and a durable mechanical connection suitable for standard 3/4" plumbing fittings. The valve’s pressure-reducing mechanism maintains a consistent downstream pressure despite fluctuations in supply, which reduces vibration, water hammer risk and premature wear of appliances. The compact design allows installation in tight spaces and its straightforward adjustment and maintenance make it practical for both new installs and retrofit projects.
Suitable for (tasks / use cases)
 Residential main water supply pressure regulation
 Protecting household appliances (washing machines, dishwashers) from high pressure
 Reducing pressure for bathroom and kitchen fixtures to prevent leaks and dripping
 Light commercial installations requiring a stable downstream pressure
When it may not be suitable
This pressure reducer is intended for cold water systems and typical domestic or light commercial use. It may not be suitable where potable water regulations require specific certification beyond general material suitability, for systems with non-standard fittings or where integrated filtration, backflow prevention or complex hydraulic controls are required. For high-flow industrial systems or applications needing remote control/monitoring, a different, specially specified regulator should be considered.
Key specifications
 Connection type: threaded 3/4" inlet and outlet with brass fittings
 Material: brass body and connections (copper-alloy components)
 Application: cold water supply pressure reduction and stabilization
 Installation position: inline, suitable for horizontal or vertical runs as specified by installer guidance
 Typical uses: residential and light commercial water systems
How to use
Install the pressure reducer inline on the incoming cold water main using compatible 3/4" threaded connections and appropriate sealing (thread tape or joint compound). Isolate the supply and drain the section before installation. Fit the valve with correct flow direction as marked on the body, then open supply and check for leaks. Adjust the outlet pressure using the adjustment mechanism according to installer instructions or measured downstream pressure; make gradual adjustments and verify stable pressure with a pressure gauge. Periodic checks for leaks and correct pressure are recommended as part of normal system maintenance.
What to consider before purchase
 Confirm 3/4" threaded connection compatibility with your existing pipework or adapters
 Ensure suitability for cold water systems and check local plumbing codes or certification requirements
 Verify required downstream pressure range and compatibility with household appliances
 Consider access for adjustment and maintenance once installed
Usage recommendations
For reliable operation, fit a pressure gauge downstream of the reducer to set the required pressure accurately and re-check periodically. Use certified fittings and follow local plumbing codes when installing; if unsure, consult a qualified plumber to ensure proper sizing, orientation and sealing.
