SAN ANTONIO Water Heater REPAIR

Water Heaters…one of the awesome, commonplace modern inventions.  We use our water heater repeatedly in our everyday lives—usually without ever thinking about it.  We take for granted the work that it does for us and the comfort it brings to us, that is, until our water heater breaks.  When we wake to find that there is no hot water for our shower, we quickly take notice of this silent workhorse. 

 

Our goal on this website is to provide you with information regarding San Antonio water heater repair.  We will discuss some of the common problems that water heaters have, how to make the decision between repairing or replacing your water heater, and how to use preventative maintenance to give your water heater the longest life possible.

 

If you're ready now to get help for your water heater repair in San Antonio, TX or the surrounding Hill Country area, give us a call.  Our Denny Plumbing professionals look forward to helping you get your routine back to normal.

Common Water Heater Problems

Let’s get started by looking at some of the common problems that can plague a conventional tank water heater and their probable causes.

NO HOT WATER

This is the worst, right?  You come home from the gym expecting to take a relaxing hot shower with your massaging showerhead, and there’s no hot water.  There are several possible causes of problems and actions you can take to remedy this situation.

            If your unit is gas-powered, check the pilot light to see if it has gone out.  If it has, relight it and your problem is solved.  (If it goes out repeatedly, there might be a problem with your unit and you should have the unit checked by a professional San Antonio plumber.)

            If your unit is electrically powered, check the breaker.  Sometimes a tripped breaker may not look tripped.  Flip the breaker off and back on just to be sure.  If the water heater begins to heat up, you’re done!  (If the breaker trips more than once, it may be a sign of an electrical problem with your water heater.  You should have the unit inspected by a plumbing expert from one of the professional San Antonio plumbing companies.)

            If your unit has power, but no hot water, it could be a sign that the heating elements, the power supply connection, the thermostat, or some other part has burned out.  While you can try to diagnose the cause yourself, it may make more sense to have a professional repair the problem for you.

Possible Repair:  Restore power to the unit; repair faulty heating elements, thermostat or other water heater part

INSUFFICIENT HOT WATER SUPPLY

When you don’t have enough hot water to go around, it can be frustrating.  Determining the cause of this hot water shortage will help to provide the appropriate solution.

            If you recently had a bathroom remodeled, you may have increased the amount of hot water you need.  A Roman tub uses 2-3 times more hot water than a standard bathtub.  Similarly, if you removed a low-flow showerhead and installed a multi-head shower massager, you will need a lot more hot water.  You may need to install a larger capacity water heater to provide the supply of hot water that you need.

            Another cause of insufficient hot water can be an increase in the number of people using the water.  If you have family or friends visiting, or college students home for winter break, you might find that your water heater is having trouble keeping up with the demand.  To solve this problem, simply organize a schedule for using the hot water so that everyone will have enough.  Run the dishwasher and loads of laundry after everyone has showered for the day.  If, however, the guests will be permanent residents in your home, you might consider installing a new water heater with higher capacity so you don’t have to do as much planning.

            A final cause of insufficient hot water is an improperly functioning water heater.  One of the heating elements may have burned out or the thermostat may be malfunctioning.  If the reduction in hot water has happened slowly, sediment may have built up inside the tank both reducing the capacity of the tank and the efficiency of the heating elements.  An experienced plumber from Denny Plumbing can help to diagnose the specific cause and get the unit back up to capacity.

Possible Repair:  install a larger capacity water heater; flush unit; replace heating elements

SPIKE IN WATER TEMPERATURE

This may not seem like a problem, after all, you have more hot water when this happens.  However, a spike in water temperature usually indicates the imminent failure of the heating elements.  Most likely you will soon end up with a no-hot-water problem.  If the heating elements are old, replacing them proactively will keep you from the frustration of waking up one morning to find there's no hot water.

Possible Repair:  replace heating elements or thermostat

POPPING NOISES WHILE HEATING

While these noises can sound a bit scary, they're not as intimidating as they sound.  Most of the time popping noises are the consequence of sediment building up on the bottom of the unit.  We have exceptionally hard water in the Hill Country area.  This hard water leads to a large amount of potential sediment build-up in the water heater.  However, regular maintenance to flush out these minerals can help prevent the need for San Antonio water heater repair. 

            While not usually dangerous, this sediment can reduce the efficiency of your water heater.  In addition, over time the sediment can eat away at the inside of the tank and cause it to rust from the inside out.  Routine flushing of the water heater can help to move sediment out of the tank and prevent it from building up inside.

Possible repair:  flush the water heater to remove sediment

WATER AROUND WATER HEATER BASE

Water unexpectedly appearing on the floor anywhere is not good, but if it is coming from the water heater, it's an even greater danger to your home.  The water heater has a permanent supply of water.  If it develops a leak, that leak will be continuously fed by the water supply coming into the tank.  In a matter of a few short minutes, you could end up with hundreds of gallons of water on the floor in your home.  If you see water around the base of the water heater, you need to look for the source of that water immediately.  Leaking supply lines can quickly and easily be tightened or replaced if needed.  However, a leaking tank should be immediately shut off and replaced before it bursts.

Possible repair: replace supply lines, tighten supply line connections, replace tank

 
FAULTY TEMPERATURE & PRESSURE VALVE

Water heaters are equipped with a temperature and pressure relief valve (T&P valve) as a safety feature to keep the water heater from becoming a rocket in the event of a malfunction.  If an excess of pressure or extremely high temperature build up inside the water heater, the T&P valve will open to let hot water move out of the tank.  Then cold water can flow into the tank.  The cold water reduces the temperature and pressure inside the tank.  The T&P valve should be tested once a year to make sure that it is working properly.  If the T&P valve is leaking or automatically expelling water, or if the valve is locked into place by mineral buildup around it, you should immediately enlist the services of a qualified San Antonio plumber like those here at Denny Plumbing to repair this safety feature on your water heater and inspect the unit for additional problems.  If you would like to see more about the risks of having a faulty T&P valve check out this video from Myth Busters about water heaters becoming rockets.

Possible repair: have plumbing profession repair T&P valve

ODD SMELL OR LOOK TO THE HOT WATER

As a water heater breaks down from the inside out, the water coming from the unit may carry tiny particles of metal.  This could give your water a rust-colored tinge or a metallic smell.  In addition, as sediment builds up in an older unit, some of that sediment may give the hot water a cloudy appearance.  If you're experiencing these problems, and your unit is over 8 years old, it may be time to consider installing a new water heater.  In the meantime, while you decide on the right type of replacement water heater, you may want to perform a water heater flush.

Possible repair: water heater flush, water heater replacement

Let's discuss some factors to consider when choosing between San Antonio water heater repair or replacement.  And take a look at how to get the longest life out of your water heater.
