Food-Grade Stainless Float Valve Kit

A 2-unit pack of fully automatic, non-powered float valves designed for safe, long-life water level control in potable and non-potable applications. Built from certified food-grade stainless steel (304), each valve features a 1/2 inch BSP male inlet and ships with precision-machined adapters for 3/4 inch and 1 inch pipes. Dimensions: ~12 cm (L) × 5 cm (W) × 8 cm (H); weight per unit: ~350 g. Silicone plunger provides resilient, quiet sealing; stainless steel mesh filter prevents clogging. Operational temperature range: 0°C to 100°C. Includes upper and side water inlet versions and two pieces of PTFE tape for secure, leak-free assembly. Functionality is purely mechanical: water level drop → float lowers → plunger lifts → flow begins; level rise → float lifts → plunger seals → flow stops. No calibration, no power, no consumables. Suited for water towers, livestock troughs, garden ponds, rainwater butts, and commercial cooling reservoirs. The dual-inlet configuration and multi-size adaptability make this kit uniquely suited to the fragmented UK plumbing landscape — where pre-1970s 1 inch iron pipes often connect to post-2000s 15 mm (1/2 inch) plastic supply lines — all handled with one unified solution.
