Having the right components for your installation means fewer headaches, fewer leaks, and a system that holds up for years. We carry lead-free silicon bronze and brass check valves from Simmons, along with fittings and manifolds compatible with standard well system piping and pump discharge connections — the same quality parts used by well drillers and licensed plumbers, not cheap box store substitutes.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCheck Valves\u003c\/strong\u003e prevent water from draining back into the well when your pump shuts off, protecting your pump motor and pressure tank from unnecessary wear. Not sure which one you need? A submersible check valve threads directly onto your pump discharge inside the casing; an inline check valve installs above ground on your discharge pipe. Many systems use both.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eManifolds and Fittings\u003c\/strong\u003e keep your installation clean and professional, reducing the number of connection points and making future servicing easier.
