Expert detailed instruction on how to fix warm water heating system problems such inadequate warm water in a gas or electric storage tank-style hot water heater.
Do you have to fix water heater problems or fix your water heater? Water heater problems usually end up being self-evident: A hot water faucet cannot summon hot water, you see leaking or puddling near the water heater, or the tank makes strange gurgling or popping sounds.
Though lots of gas utility companies will make a free house call to fix problems with a gas hot water heater’s burner or the gas supply to the tank, you’re on your own when it pertains to other hot water heater problems. It helps to understand how to resolve standard interruptions yourself, as talked about below. For more difficult issues, call a certified local hot water heater repair work individual.
Common hot water heater problems include a leaking tank, insufficient warm water, water that is too hot or not hot enough, odd sounds in the tank, and tarnished or smelly water. The majority of these type of problems are reasonably easy to identify and manage if you comprehend how hot water heater work
No Hot Water
With a hot water heater, the most typical problem is that it doesn’t heat water at all. Since a gas water heater runs much in a different way than an electrical water heater, handling a water heater that doesn’t work at all will depend on whether it is gas or electrical. (A gas water heater has a burner at the bottom and a flue at the top; an electrical one is powered by a large electrical connection.)
Insufficient Hot Water or Water Too Hot
Two of the most common problems with hot water heating units are that they produce water that is either not hot sufficient or too hot. The quickest and most obvious first step is to change the temperature dial on the front of the hot water heater, wait a bit, then examine the water temperature level at a faucet. But if changing the temperature dial doesn’t do the trick, attempt the approaches below.
Not Enough Hot Water
A small hot water heater is typically the culprit if it appears like you never have enough warm water in your house. If the issue is chronic–or if you’ve increased your needs for warm water by installing a huge new soaking tub or high-flow shower head–you’ll probably need to get a new, larger water heater. Make sure to check out tankless water heaters because, with this type, you never ever lack hot water.
On the other hand, if you’ve had adequate warm water in the current past however your water heater suddenly seems to supply less warm water, first check the dial on the water heater, as talked about above.
KEEP IN MIND: If outside temperature levels have dropped substantially, your hot water heater should work harder to heat and maintain the cold inbound water, and the water cools more as it travels through pipes that run through unheated spaces. This requires changing the hot water heater’s dial to a somewhat hotter temperature level.
Also ensure the water heater isn’t really leaking. If neither of these concerns are the problem, flush the hot water heater tank to be sure mineral deposits are not reducing the heater’s performance.
This is also a good time to test that the temperature-pressure relief valve, which keeps pressure from developing excessive in the boiler, is in correct working order. Raise or lower its manage. Water should drain from the overflow pipeline.
- If these measures do not get the job done, the dip tube that supplies cold water to the tank might be broken or split. This plastic tube is expected to direct cold water to the bottom of the hot water heater tank, however, if it breaks or splits, cold water gathers at the top of the tank and blends with the warm water that is on its method to the hot water pipelines.
- Either have the dip tube replaced by a water heater repair pro, or, if the water heater runs out guarantee and showing other signs of age, consider replacing it.
Warm water Is Too Hot
- Clearly, the first thing to do if your warm water is too hot is refuse the temperature level on the hot water heater’s thermostat dial. Note the present setting (or mark it with a felt-tip pen), and after that turn it toward a cooler setting, wait a couple of hours, and see if the problem is resolved.
- If steam or exceedingly warm water shoots out of faucets, or you hear boiling sounds inside the hot water heater, the device may not be turning off at its set temperature.
- The task of the temperature-pressure (TP) relief valve is to launch excessive pressure from steam buildup, however this valve may have been incorrectly installed, or it may be malfunctioning. In any case, this condition can be unsafe, both since warm water and steam can heat people and due to the fact that the water heater might rupture.
- Turn down the water heater’s temperature level and permit the water to cool, then replace the water heater’s pressure relief valve.
Hot Water Is Discolored or Smells Bad
If your water has a strange odor, first figure out whether the problem is with the source water or the water heater. If the problem is with both the hot and the cold water, or if just the cold water smells, the problem is more likely with your source water. Iron, copper, and other minerals can cause staining in water. To fix these type of issues, think about installing a whole house water filter and/or a water softener.
If the issue is just with the warm water, for the most parts the smell is caused by a reaction in between the warm water heating unit’s anode rod and water that has a high concentration of sulfates. Let the warm water run for two or 3 minutes. If it smells a bit like rotten eggs, you can attempt flushing the warm water heater tank. If this does not solve the issue, the anode rod may require replacement by a water heater repair work individual.
If you smell a garlic-like fragrance, the pilot light might have headed out. Turn the gas valve control to OFF (you may need to lower to turn it). Wait up until the gas smell has actually dissipated prior to relighting the pilot light. If the gas smell is strong and doesn’t dissipate, immediately switch off the gas supply valve, aerate the space, and call a plumbing professional or your gas utility business from a remote location.
Hot water heater Makes Noises
- Noises coming from a hot water heater can be caused by expanding and contracting metal parts; drips; or, most likely, minerals and hard water scale accumulations inside the tank or on an electric water heater’s heating aspects. When warmed, dissolved hard water minerals recrystallize and form scale that cakes onto interior surface areas, making the hot water heater less efficient and most likely to fail.
- To lessen destructive minerals through ionization, hot water heater have a magnesium or aluminum anode rod, inserted through the top of the tank. To avoid scale in the first place, every few months flush out the tank. See Not Enough Hot Water for total directions on how to do this.
Here are some common hot water heater sounds you may hear:
Hot water heater pops, bangs, or gurgles
These sounds are caused by the buildup of hard water sediment heating up and blowing up inside the tank. You can flush out the tank yourself, although by the time you’re hearing this noise the sediment chunks may be too large to go through the drain valve.
If you have an electric hot water heater, these sounds could indicate an accumulation of scale on your heating elements; it may be time to change these.
Hot water heater makes a boiling noise
If water sounds like it is boiling inside the tank, this might indicate overheating and an unsafe pressure accumulation. Call a service expert right away.
More Water Heater Repairs & Tips
Here are a few useful ideas relating to safe, effective water heater usage:
- Check the water heater’s temperature setting. Set the temperature control to about 150 degrees F. or lower if you have no dishwashing machine or if you have children or senior individuals in the home who might heat themselves.
- Insulate warm water pipes. To minimize the energy it takes to warm the water, insulate your pipes if they run a long way from your heating system to your faucets. If you can gain access to your hot-water pipelines, from the basement, for example, put foam pipeline insulation sleeves onto them to minimize heat loss.
- Periodically examine the temperature-pressure relief valve, which keeps pressure in the boiler from developing excessive. Lift or decrease the lever on this valve. Water ought to drain from the overflow pipe.
