Inline Spring-Loaded Check Valve

This 2-inch FIP inline spring-loaded check valve stops reverse water flow in plumbing lines. Cast brass body and brass spring resist corrosion in potable and non-potable systems. Suitable for installers who need a straight-through flow path with automatic closure when pressure drops.

Cast Brass Construction and Approvals

The heavy-duty cast brass body and brass spring provide rust-resistant durability across multiple approved applications. Secure female iron pipe threads create leak-resistant joints without additional sealing compounds. These materials and certifications allow the valve to meet code requirements for backflow prevention in residential and commercial supply lines.

Lead Content and Handling Limits

California Proposition 65 warnings confirm the valve contains lead, a chemical known to cause cancer and reproductive harm. Installers must wash hands after handling and should not use the valve in systems where lead-free components are mandated by local regulation. The spring-loaded design does not eliminate the material restriction for certified lead-free installations.

Questions about this item

How often should the brass spring be inspected or replaced?

The heavy-duty brass spring is built for long service; inspect it during routine plumbing checks and replace only if reverse flow or leakage appears.

What pressure limit does the valve reach first under continuous flow?

The valve is rated for 150 psi working pressure, so sustained pressure above that level will be the first limit encountered.

Does the cast brass body run hot or add noise when water runs all day?

The cast brass construction resists rust and operates quietly; it does not generate noticeable heat or noise during continuous water flow.
