The built-in check valve uses a spring-loaded mechanism to allow water to flow into the pump while automatically closing to prevent backflow when the pump stops — maintaining the system's prime and protecting pump integrity.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What pipe sizes is this copper bottom valve compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: This valve uses a quick-release union connection style and is designed for insertion into standard pipe configurations. Please verify the pipe diameter matches the valve's fitting size before purchasing. Check the product variant options or contact us for specific sizing guidance.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this valve suitable for outdoor or irrigation use?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The solid copper construction makes this valve highly resistant to corrosion and well-suited for outdoor environments, garden irrigation systems, agricultural water transfer, and other demanding water handling applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does the filter screen do, and how do I clean it?\u003c\/h4\u003e\n\u003cp\u003eA: The integrated mesh filter screen traps sediment, sand, and debris from entering your pump system. To clean it, simply disconnect the valve using the quick-release union fitting, remove the screen, rinse it thoroughly with clean water, and reinstall. Regular cleaning extends the life of both the valve and your pump.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a bottom valve and how does the check valve function work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A bottom valve is installed at the inlet of a self-priming pump's suction pipe, typically submerged in the water source.
