Hydro-mechanical drain cleaners & Electric drain cleaner info chemical Man
Hydro-mechanical drain cleans use high-pressure water to break up obstructions and flush these smaller particles down the drain.Most municipal building codes mandate that drain plumbing increase in diameter as it moves closer to the municipal sewer system. I.E., most kitchen sinks evacuate water with a 1 1⁄2-inch drain pipe, which feeds into a larger 4-inch drain pipe on the main plumbing stack before heading to a septic tank or to the city sewage system.
