This 1/2 in Male x Female NPT brass check valve stops backflow in a single, easy-to-install fitting. The stainless steel spring keeps the valve responsive in vertical or horizontal installs, and the brass body is listed to NSF/ANSI 61 for safe potable water use. With a low opening pressure of about 45 PSI and a max rating of 230 psi, it's built for a wide range of systems — RV and residential water heaters, wells, pumps, tanks, solar setups, and general plumbing lines. Standard 1/2 in NPT threads connect directly to existing fittings, no adapters required.
  • ONE-WAY BACKFLOW PROTECTION — Allows water to flow in one direction only, stopping backflow into your freshwater line — the stainless steel spring keeps the valve responsive whether it's mounted vertically or horizontally.
  • BRASS BODY, NSF/ANSI 61 LISTED — Solid brass construction is listed to NSF/ANSI 61 for safe potable water use, resists corrosion for long-term reliability.
  • 1/2 IN MALE x FEMALE NPT — Standard NPT taper thread connects directly to existing 1/2 in fittings — no adapters needed for most water heater, pump, or supply line installs.
  • VERSATILE APPLICATION — Works for RV and home water heaters, wells, pumps, tanks, solar systems, and general plumbing — not limited to a single use case.
  • LOW OPENING PRESSURE, HIGH MAX RATING — Opens at approximately 45 PSI with minimal back pressure required, rated up to 230 psi max — reliable flow control across a wide range of systems.
