The GT Water Products MP1600 Master Plunger is a commercial-quality, funnel-nose plunger specifically engineered for modern low-flush and high-efficiency toilets (1.28 & 1.6 GPF). Its patented air relief valve eliminates overflow, while the extended funnel design creates a perfect 90-degree seal to prevent slippage and messy splashback. Made of durable, high-strength polyethylene in the USA, it delivers a powerful 8-cup water displacement to clear tough clogs fast. The complete kit includes a discreet black storage bucket that holds the plunger upright, making it the ideal, no-fuss solution for homes and commercial settings.
