Drain King H34 — Unclogs Main & Exterior Drains (3-4 Inch) | Made in USA

Overview

Drain King H34 is the original water-powered drain cleaner, proudly made in the U.S.A. It expands from 3 to 4 inches inside the pipe to create a secure seal, which concentrates the cleaning force from your hose. The built-in pulsating jets then target the clog, aiming to restore flow without harsh chemicals. Designed for main sewer lines and exterior drains, including basement and deck channels, it fits 3 to 4 inch openings and serves as a practical tool for homeowners and professionals alike.

When you connect a standard hose, Drain King H34 activates a powerful, water-driven pulse that can help dislodge buildup and clear slow or clogged drains. Whether you’re dealing with a backed-up basement drain or a stubborn outside deck drain, this device provides a versatile option to address common drainage bottlenecks. The tool’s durable construction and 3–4 inch compatibility add flexibility for various plumbing setups, making it a go-to for quick diagnostics and maintenance.

How It Works

As water flows through the hose, the unit inflates to seal the pipe, redirecting water through targeted jets. The pulsating action assists in loosening mineral deposits, grease, and debris, while a fresh rinse helps carry those fragments away. The result is a clearer drain and reduced backflow in many scenarios, though actual results depend on clog type and pipe layout.
