Tips on Preventing the Corrosion Menace in Your Hot Water System

In homes, hot water systems are valued for providing hot water for domestic use. However, the metal components of these systems can start corroding over time. If this problem isn't addressed early enough, you may end up getting little to no water at all. Plus, your energy bills may rise to system inefficiencies.

Keeping in mind that prevention is always better than cure, here are some ways to protect your hot water system from corrosion.

Inspect and Replace the Anode Rods

Anodes perform an all-important function within the hot water system by preventing corrosion within the water heater unit. It does this by allowing corrosion to take place on the anode rods instead. This explains why these rods are also known as the 'sacrificial' rods.

Over time, however, the anode rod may get encased with calcium carbonate. This will create room for corrosion to take place within the heating unit. 

Preventing this from happening requires routine checks by a professional to ensure the anodes function in top shape and any need for replacement is addressed at the shortest time possible.

Ditch Traditional Pipe Nipples for Plastic-Lined Ones

Usually, water heaters consist of pipes made of copper and brass while most linings are made of steel. It is important to note that copper and brass are resistant to corrosion, unlike steel linings. This leaves steel linings susceptible to corrosion at any point of contact with the copper and brass pipes in the presence of water. 

To protect your steel linings from corrosion, it is imperative to upgrade the pipe nipples to plastic-lined nipples at areas of where copper and brass are exposed to steel lining.

Install Galvanised Unions That Feature Plastic Nipples 

Galvanic corrosion usually occurs on the heating element of your hot water system. This type of corrosion can easily cause your hot water system to fail as it directly affects the efficiency of the heating element. 

The heating element consists of steel and copper sheathing. In the presence of water, both electrolysis and corrosion are likely to take place. It is important to install galvanised unions that have plastic nipples at the top section of the storage tank.

Corrosion is bad for your hot water system and can result in premature system failure. With that said, it is best to be proactive when it comes to protecting your water heater. The above-highlighted tips can go a long way in helping you achieve this goal.
