Method of Cleaning Out a Water Heater

原文（中国語）

A method for removing built-up solids from a water heater using a vacuum-based clean-out device is disclosed. The method includes disconnecting power and water, draining the heater, and inserting a vacuum pipe through an access opening. Suction is applied while an articulating joint and pull cord mechanism direct the vacuum pipe to remove sediment. Additional steps include rotating the pipe, adjusting its length, using sensors for positioning, and applying vibration to dislodge deposits. The method supports insertion through a heating element port or drain valve opening and allows flushing with water post-cleaning. Compatible with shop vacuums, wet/dry vacuums, and central vacuums, this method improves cleaning efficiency and heater performance.
