guideline for hot water system repair is
an approximation of the work tasks , materials and tools required for a hot water system, inspection,
maintenance and/or repair. The intent of this page is to give a person a foresight of the scope of such an
Following is brief discussion of the potential failure modes for the individual components and devices
are comprised in hot water system repair.
Leaks are visible. The cause can be simply a fitting and/or valve mechanical failure. However, if caused by corrosion, it will require further investigation. Mechanical plumbing adjustments , refitting and/or a valve replacement can correct most of these problems.
pressure relief valve can fail due to deposit build up from affecting its
pressure setting . It can relieve prematurely that would appear as intermittent
leak, or, not relieve sufficiently. Activate it manually to determine
sufficient water flow.
Hot water tanks are
provided with a sacrificial anode as a means to protect hot water failure and /or tanks fittings from corrosion. This
anode may fail; i.e., broken off tank body
or consumed . Anode can be
replaced, if tank is still considered
serviceable. Otherwise, if tank leaks, one might consider replacing tank as a
Heating elements can
fail as a result of corrosion and/or material build up on element, i.e.,
calcium salts and other minerals deposit build up. Over time the salt deposits
coat the elements with very thick hardened layer rendering them virtually
ineffective, causing the elements to overheat and fail. Also, aggravated by corrosion, the units can
short-out. Test the elements'
resistance, normally between 12 and 14 ohms. The heating elements can be
The heating element control controls the power feed, turning the power on and off to the individual elements depending on water temperature. These can burn out due to frequency of switching or from heating element failure mode.
The physical work is relatively within realm of DIY person, a would be Jack of all trades.
The hot water system repair diagnostics can be a bit of a puzzle, as components and devices are enclosed and under pressure. They also encompass the technical knowledge of a number of trades. Acquiring the specialized components can also be a challenge . For the uninitiated, the research and sourcing the tools and components parts that are at times unique can take considerable amount of time.
However, most households cannot afford the time for the preparatory work. This is especially true, if hot water system has already failed. Then, unless well equipped, you are faced with a messy tasks to carry out the fix.
For the enterprising
individuals, determined DIY that are prepared to take on the task but require
technical support, we can provide advisory services for a fee.
Irrespective of the mode of failure, a thorough inspection of the system is required to determine the cause or causes. To do this, one has to do the following tasks;
If tank, tank fittings and piping are serviceable one can then proceed to replace the failed components. For example,
Hot water system
should be good to go.
To determine the cause of problem in the hot water system requires opening the system up, as inadvertently, the cause is hidden in the internal water pressurized components.
