An apartment owner called for a plumber to replace one of the leaking pipe lines. The plumber arrived and found that the galvanized iron pipes are deteriorated and corroded. He advised the apartment owner to replace the galvanized iron pipes with the PVC pipes. Why did the plumber give the above suggestion?

Explanation

PVC pipes are polyvinyl chloride pipes which are thermoplastic in nature and more durable as they are completely rust free and less expensive than galvanised iron pipes. Though galvanisation prevents rusting, since the pipelines are in continuous contact with water, the coating may get worn off over a period of time and it may be corroded.
