Repair Water Heater
Mock Plumbing replaced a leaking copper flex supply line. This specific supply was on the hot side. Most of the time, the hot water side fails first. This is due to the temperature which is slowly taking its effect because most materials usually soften when heated.
With the increasing cost of copper, stainless steel is now slowly replacing some parts of the supply line that are made of copper. As shown in this post, a stainless steel supply line replaced the damaged one. Although tightening may stop the leak temporarily rest assured it will leak again. For permanent leak stoppage, Mock Plumbing Repairs in Sugar Land strongly recommends replacement of these damaged water heater supply lines.
