Plumbers, irrigation installers, pool technicians, and DIY builders who work with PVC pipe systems need a PVC check valve that seals decisively, resists corrosion, and installs without specialist tools. This solvent-weld foot valve and bottom valve combination is engineered for exactly that job.\u003c\/p\u003e\n    \u003cp\u003eEach valve body is manufactured from rigid PVC (polyvinyl chloride), offering excellent resistance to chlorine, mild acids, and common water treatment chemicals. The solvent-weld (Klebemuffe) socket ends create a permanent, leak-free bond with standard PVC pipe. Available in seven sizes spanning DN15 to DN65, with inner diameters from 20 mm (approx. 0.79 in) up to 75 mm (approx. 2.95 in), covering the most common residential and light-commercial pipe schedules.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include submersible pump foot valves to prevent siphon-back in wells and cisterns, inline check valves for drip irrigation and sprinkler systems where backflow protection is required, and bottom valves on chemical dosing lines where a corrosion-resistant PVC solvent weld check valve outperforms metal alternatives.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard PVC pressure pipe — DN15 (20 mm OD), DN20 (25 mm OD), DN25 (32 mm OD), DN32 (40 mm OD), DN40 (50 mm OD), DN50 (63 mm OD), DN65 (75 mm OD).

A foot valve (Fußventil \/ Bodenventil) is a specific type of check valve designed for vertical installation at the bottom of a suction line, typically submerged in a well, tank, or cistern. It keeps the pump primed by preventing water from draining back when the pump stops.

For best results, clean and dry both the pipe end and the valve socket, apply PVC primer to both surfaces, then apply an even coat of PVC cement and push the pipe firmly into the socket with a quarter-turn. Hold for 30 seconds and allow the joint to cure fully before pressurising — typically 15–30 minutes at room temperature, longer in cold conditions.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eIs this valve suitable for irrigation systems?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eYes.
