Why is my hot water system not working?

You anticipate hot water to flow out of the faucet or shower when you turn it on. Instead, only cold water comes pouring from the faucet. Taking a chilly shower because there is no hot water may be a real pain in the neck. You probably might be thinking of your water heater’s efficiency or if there is a natural gas leak due to the cold water it releases. There are numerous reasons why your hot water system is not working effectively anymore.

Some causes of water heater issues

Leaking storage tank

The water heater will not function if there is no water in the tank for the water heater to work. If you can’t get hot water to run, the tank is most likely leaking. An empty tank is a significant inconvenience and wastes a lot of energy.

Explosion or leakage of natural gas

A water heater natural gas leak is both inconvenient and hazardous. Call your gas provider right away if you suspect a leak to avoid further problems.

Problems with water heaters

You may save money if you have an efficient water heater. It is possible to avoid waking up to cold showers if you have a gas, solar, or electric water heater in your home. However, should your gas run out or if you are experiencing electrical faults, it may be time to have your system looked at.

Gas valve not working

If 24 volts is flowing from the board to the gas valve terminals and you don’t hear the tiny clicking sounds the internal valve produces, you may have a faulty gas valve.

Thermostat not functioning correctly

When the HVAC system in your building refuses to come on or react to the thermostat, you’ve got a faulty thermostat.

Size of the storage tank

If your tank is too tiny, you’ll waste energy and run out of hot water more quickly in your home. It may have done its job well when it was only you using the appliance.

However, your family’s need for hot water and hot baths increased exponentially as your family expanded. A bigger hot water tank is thus required. Electric water heaters take longer to heat than gas water heaters, so bear that in mind while making the switch.

Poor weather for heating

The time it takes to heat water is determined by the temperature of the surrounding air. A water heater’s energy efficiency and functionality may degrade significantly in the winter, even in warmer areas.

You may have water issues if you reside in a region that has frequent cold snaps. To properly insulate the appliance, you may have to wait until it becomes cold before using it.

Heating element function failure

Water heaters often come with a ten-year warranty to ensure that you get hot water for at least that long. Parts of the water heater may wear out and fail after ten years.

How to fix a faulty water heater

Showering last in a large home means you’re likely to experience teeth-chattering ice-cold water. In the absence of a swarm of people, it’s time to evaluate your electric water heater if you’re experiencing water issues.

Before you begin, make sure all electrical devices are off. Priority is given to safety. To begin troubleshooting an electric water heater, make sure that it is entirely unplugged before you begin. Turn off the heater’s fuse or circuit breaker to do this.

Water temperature issues

Water temperature difficulties may be caused by a variety of electric water problems. No hot water, insufficient hot water, or overly hot water are all possible symptoms. Electric thermostat failure, a bad upper heating element, or a lack of electricity may cause no hot water. Begin by ensuring no electricity problems exist.

First, make sure all components and circuit breakers are working properly by replacing blown or tripped fuses. Next, check whether the thermostat for the electric hot water is receiving electricity. Replace the component if it proves to be defective after testing it. The thermostat or electric water heating element should be replaced if electricity is received but still not functioning.

Not enough hot water

Secondly, if the water isn’t hot enough, it may be due to faulty systems. For instance, a broken heating element or thermostat, an inadequate water heater, or even crossed hot and cold connections could be the probable cause. Be sure the heater can hold 75 percent of its capacity in hot water to rule out an undersized unit.

Switch off the water supply and turn on a hot water faucet to rule out a crossed connection. If water is still flowing, search for a crossed connection. Replacing a heating element is easy if you first remove any sediment from the tank before checking for power and electrical continuity.

The top thermostat should be checked first, followed by the lower one, and either should be replaced if it isn’t functioning. In most cases, when the water is flowing too hot, the thermostat has to be lowered. The thermostat should be adjusted between 110 and 140 degrees Fahrenheit on both the upper and lower sides of the thermostat dial.

Leaking water

Incorrect temperature and pressure relief valve (T&P) leaks may be caused by a defective gasket, high pressure, or overheating. A faulty T&P relief valve can also create a leak from an above or nearby plumbing connection, as well as loose heating element bolts.

  • Place a bucket beneath the overhead pipe to catch any leaks, open the T&P valve and flush out any debris. If the leak persists, repair or replace the valve. Reduce the temperature on the thermostat to alleviate any remaining high pressure or heat.
  • Verify that there aren’t any weak or loose pipe connections and tighten them with a wrench, taking caution not to overtighten.
  • Make sure the fasteners holding the heating element in place are secure and tighten them if necessary. Replace the gasket on the heating element if the leak persists.
  • See whether there is a leak in the storage tank. Corrosion or other problems, like faulty O-rings, may cause storage tanks to leak. You should always have a few spare O-rings available in case you need to replace one.

Blemish or odour

When water becomes rusty, it’s either due to corrosion within the tank or a failed sacrificial anode rod. Replace the anode rod if it fails with a magnesium one.

If the sacrificial anode rod decomposes, hydrogen will be released, giving off a rotten egg stench. Flushing the water heater is the first step in resolving the issue. A two-point solution of three percent hydrogen peroxide in 182 Litres of water should be used for two hours to treat the tank and pipes. Alternatively, if the stench continues, switch to a zinc-alloy anode. If the odour persists, try installing a plastic-lined heater instead.

Noises from heater

Overheating may produce a low, rumbling noise indicative of boiling water. A simple water heater flush will solve the issue.

If you hear a high-pitched whining noise, check for scale accumulation on the electrical heating components. First, cleanse the water heater to get rid of the problem. After that, flush out the tank and components of the water heater of any built-up sediment. Finally, use high-surface-area, low-watt-density heating components for better heat transmission.

Tips to avoid leaking from your water heater

When you have water leaks, the plumber may learn a lot about what’s wrong by looking at where the leak is. Because of where the leak is, the plumber can rule out distinct possibilities as being the source. Homeowners would also benefit from having a basic knowledge of what the different leak sites imply and how to fix the leaks. Due to this, plumbing repairs are considerably more straightforward for homes since professionals will know exactly where to start looking when they arrive.

Most water heater leaks may be avoided by homeowners taking a few simple steps. These activities are fast and straightforward, and they stop leaks in their tracks. While some leaks are unavoidable, homeowners are often surprised to learn how much power they have over leaks.

Leak detection relies heavily on the amount of time it takes for a leak to appear. The shorter time it takes for homeowners to discover a leak, the better off they’ll be. However, homeowners may avoid leaks altogether by taking preventive steps. Here’s how to prevent leaks in your house.

Tighten any slack in the system

Start by making sure everything on the water heater is snugly screwed together. Tighten any loose components as frequently as required to prevent water leaks. A wrench is all you’ll need.

Maintenance to avoid problems later

A plumber’s regular maintenance ensures that the electric hot water system is free of leaks. Plumbers may examine the whole plumbing system during maintenance inspections, which includes the water heater. All components are examined to determine whether they have the potential to leak in the future. If any are found to be faulty, they are replaced.

Drain and clean the tank before reinstalling

Sediment accumulation in a dirty water heater tank increases the risk of cracking. Cleaning the septic tank is a do-it-yourself project for homeowners. Once the water has been drained, apply a bleach-water solution to remove any mould or mildew that has developed. Sediment collection will not harm the tank due to using this method, which also improves water quality.

Respond right away

If a water heater leak occurs, homeowners should act quickly to avoid more damage. Floods are more likely to occur if leaks are left unattended for an extended length of time. Aside from that, if pressure builds up in the tank for an extended period without being relieved, the heater may explode. Be on the lookout for leaks as soon as they occur to avoid situations like these.

Water heaters should be checked regularly

Finally, in addition to routine maintenance, homeowners should have their water heaters inspected regularly. Check for cracks and loose components, then clean out any sediment buildup you discover. Water heaters need to be monitored by homeowners so they may be alerted if anything goes wrong.

Maintaining your hot water system

You and your family’s well-being depend on the hot water system in your house. It’s essential to keep your hot water system in excellent working order, and the good news is that you can do something about it. Following these simple guidelines may help keep your hot water system and your family healthy and happy.

Once a month, be sure to check on your water heater. From the exterior, look for any cracks, water leaks, or general system wear and tear. Every month, take five minutes to do this quick check to see if there are any issues. You may also call an expert plumber to do this job. They can get the job done successfully and can give you recommendations on what to do with your water heater issue.
