Domestic Water Heater Systems Safety Guidelines

Many times plumbing mistakes are made in the heating and hot water systems when they are installed. Plumbing codes for these systems have evolved to address new situations that exist in today’s homes. When these codes were written many times, there were not the facilities or equipment available that we have today to deal with the growing situation that exists with water heaters and water softeners.

In actuality, no model plumbing rule addresses maximum flow capacity or the need for drainage. Mis misinterpreted codes from past years. There have always been individuals claiming that the maximum allowable flow setting or temperature on a water heating fixture is 120 F. The only setting that can be used is the full capacity setting which is normally much lower than the 120 F that is typically specified on the fixture tank. The idea being that since the water coming into the fixture is heated by natural gas, it would be prudent to use a lower temperature setting to protect the plumbing system and prevent leaks.

Leaks in any piping system are a problem when they occur. It is imperative that if the water temperatures become hot enough during the day that Leaks must be repaired as soon as possible. These codes clearly state that if the hot water system or plumbing fixture outlet temperatures become extreme due to high water temperatures, the individual using the hot water system and plumbing fixture should turn off the hot water supply system and call a plumber to repair the leak. When it is noted that multiple leaks have occurred, then a plumber should be called and the hot water system and plumbing fixture outlets and temperatures corrected as soon as possible.

The National Plumbing Code is also important for domestic hot water systems Adelaide temperatures because this information is required for the models of hot water systems on the market. For the most part, the various plumbing codes for each model on the market follow the same guidelines. However, there can sometimes be slight variations. This information is required because each model on the market will be different and have its own unique set of specifications that must be followed. If the code requirement for a certain fixture outlet is not followed, it could lead to an unsafe situation. As a result, it is vital that if the plumbing codes for a model are different, then these specific codes are followed.

Different guidelines must be followed for the cold water supply to a water heater. One of the primary considerations for a cold water supply is that the cold water supply should never be warmer than the water heater itself. This can lead to the occurrence of damage to one or both the heater’s components. One way to help prevent damage to one of these heaters is to use a low amperage cold water supply in conjunction with the high amperage hot water supply. This way, you can protect both of these appliances from damage that could occur.

A special valve that is part of hot water systems Adelaide called a scald valve must also be used. The scald valve is used to prevent the water from heating up before the valve being closed. A scald valve also has a function because it allows the supply valve to open during a shut down of the hot water system. If the valve should remain closed, it has a secondary safety benefit in that the supply valve prevents the rest of the components of the valve from becoming hot when the hot water system is turned off. This can help to prevent damage to some parts of the water heating equipment.
