PURPOSE: An anti- corrosion pipe is provided to prevent the backflow of residues as a sill is formed into a zigzag shape to minimize a clearance. CONSTITUTION: An anti- corrosion pipe comprises a meter, a strainer(30), and a connecting straight pipe. The strainer filters foreign matters in tap water flowing into the meter. The connecting straight pipe connects the meter to the strainer. The strainer comprises a body(31) and a filter member(34). The tap water flows into the passage space part of the body. The filter member is installed inside the body, and filters the foreign matters in the tap water. A first cleaning hole(80) is formed in the lower part of the filter member. A cleaning cap(81) opens and closes the first cleaning hole.
