Relief & Reducing Valves

Safeguard your plumbing system and ensure optimal water flow with our selection of relief and reducing valves! These essential components play a vital role: air relief valves prevent air buildup that disrupts flow, vacuum relief valves guard against pipe collapse by allowing air in, and pressure reducing valves regulate incoming pressure, protecting pipes and appliances. Shop now and invest in the peace of mind that comes with a healthy and balanced water system!

FAQ's

What is a relief valve and what does it do?

In irrigation systems, a relief valve, also called a pressure relief valve (PRV), acts as a safety guard against pressure spikes. Here's how it protects your irrigation system:

Prevents Damage: Imagine your irrigation system as a network of pipes. When water pressure builds beyond a safe limit, the relief valve acts like a release valve. It opens and diverts excess water, preventing pipe bursts, sprinkler head damage, and potential leaks.

Protects Components: High pressure can also harm pumps, valves, and other irrigation system components. The relief valve safeguards these by ensuring pressure stays within the recommended range.
