Water Heater Repair Basics

Water heaters are crucial equipment in any home, but sometimes they can break down. Usually, these units are relatively inexpensive and easy to fix for the homeowner.

Water Heater

Before you start working on the water heater, make sure that the power is completely cut off. You will need a voltage tester to check for line voltage, and you should also remove the plastic safety guards and access panels from each element. However, if you need professional help, contact Water Heater Repair Denver now!

The thermostat controls the temperature of the water in your hot water heater. If it is set too low, the water will cool before being distributed to your faucets. If the temperature is too high, your hot water may be scalding. A tripping thermostat can be caused by many things. One common cause is a dirty anode rod. This can be easily fixed by flushing it out. Another common reason for a tripping thermostat is a defective upper heating element. When the upper element fails, the water heater no longer heats. The problem can be corrected by locating and pressing the reset button located on the front of the tank.

If you are unable to get the upper thermostat to reset, it is probably time to replace it. To do this, shut off the power to your water heater and remove the access panel and insulation on the top of the tank. Locate the two wires positioned above the reset button, and then use a multimeter (try the UEI UTL33T digital) to check for voltage. The upper element should be receiving 240v.

Next, locate and remove the lower thermostat by unscrewing it. Be careful not to pull it out by the wires. You can find a new replacement at a hardware store, home center, or plumber’s wholesaler. Make sure you buy a model that fits your specific water heater. Once you have the new thermostat, turn the power back on and reconnect the wires. Finally, replace the thermostat cover and insulation.

If the thermostat is working correctly, the meter should return a zero value when you touch it to each terminal screw. A wide difference between the setting and the actual water temperature will indicate that you need to replace it. Occasionally, the temperature setting can get loose or even fall off entirely. This should not affect its function, but it is a good idea to periodically clean the thermostat to remove any sediment. This will help prolong the life of your water heater. In addition, you should also flush the tank regularly to keep the sediment out.

Pilot Light

The pilot light is a small flame that heats up the gas inside your water heater. This helps the thermostat detect that it’s time to turn on the heating elements so that you can have hot water. A service technician can make sure that the flame is burning at a proper rate and that it’s using as much gas as necessary. This can prevent your utility bill from going up unnecessarily.

If the pilot light won’t stay lit, it could be a sign that there’s a problem with the thermocouple or that the pilot itself needs an adjustment. It could also mean that the gas supply isn’t reaching the flame — a kink in a flex line or a gas valve that isn’t open properly can cause this issue.

A leaking pilot light is a dangerous problem that should be addressed as soon as possible. This can cause the tank to leak gas, which can lead to an explosion or a fire. If your pilot light is leaking, you should turn off your water heater immediately and call a professional.

You can try to relight the pilot light yourself if you follow safety precautions. First, shut off your water heater by turning the gas valve to the “off” position. You should also turn off the electricity to your water heater. Next, use a lighter or match to apply flame to the tip of the pilot light. Continue applying flame until you see the pilot light glow, and then wait a minute or so to ensure that it stays lit.

Water that smells or looks discolored can indicate a problem with your water heater. A clogged filter may be the culprit, or there might be a problem with the incoming water. In some cases, these issues can’t be fixed and you might need to replace your water heater.

If your water heater is making loud noises or sputtering, it’s probably time to call in a service technician. These are all signs that your unit is overheating and that it’s time for a repair or replacement.

Dip Tubes

A dip tube is the unsung hero of a water heater. The tube transports cold water to the burner located near the bottom of the tank. Without it, a water heater would only provide tepid water. Dip tubes are often made from heat-resistant plastics to prevent metal corrosion and damage to the sacrificial anode rod.

Like many plumbing parts, a dip tube is prone to breakage and should be replaced as needed. However, the task of replacing a dip tube can be daunting for those who don’t have the experience and knowledge required to perform the job properly. This is where a professional plumber can help.

Replacing a dip tube can be as simple as switching off the power to the heater (circuit breaker for an electric unit or gas control dial for a gas water heater), draining the tank, opening a hot water faucet in the home to release air, disconnecting the dip tube from the inlet port nipple on the water heater, and installing a new one. A new tube should be cut to length so it extends below the nipple and off the bottom of the tank. It should also be positioned so it points away from the drain valve to avoid mineral deposits.

Depending on the manufacturer, different tubes have different curves. Some have a mark that indicates the direction it should point so that the tube can swirl water around inside the tank. A curved tube is better at resisting rust and corrosion but requires more maintenance because it may require periodic flushing.

The last thing you want is to discover a piece of disintegrating plastic in your hot water! This is what happened to some units during the ’90s, when a water heater manufacturer produced defective dip tubes. These tubes would deteriorate into a variety of sizes of plastic debris that clogged strainers and screens in appliances and faucets.

The best way to prevent this is by switching to a higher-quality tube from a reputable manufacturer like AO Smith, Rheem, or Bradford White. These companies use patented technology to manufacture dip tubes that are less prone to corrosion and have a longer lifespan than traditional plastic ones.


Your water heater has a tank that holds the hot water that powers your home’s plumbing and appliances. If your hot water isn’t working, there could be a problem with the tank itself.

Water tanks are prone to corrosion from the sediment and minerals in your water. This can be especially bad if you don’t drain your water heater about twice per year to remove this material. If your water has a sulfur smell or is discolored, this could be the result of this. If this is the case, turn off your water and drain your tank. If this doesn’t get rid of the odor or discoloration, you may need to replace your anode rod.

Another common problem with water heaters is that they simply don’t produce enough hot water. This can be caused by a number of factors, including an undersized water heater or crossed hot and cold connections. A professional plumber can help you determine if your tank is the cause of this issue and can recommend a solution.

If you have a gas water heater, you should check the temperature and pressure relief valve (TPR). This is a safety device that releases excess pressure from your water tank. If this isn’t working correctly, it can lead to a dangerous leak. This is usually a simple fix, but you’ll need to contact a professional plumber to take care of it for you.

Lastly, if you notice a lot of puddles around your water heater, it’s likely that there is a leak somewhere. This is a serious issue that can quickly lead to a flood. It’s important to shut off the water supply and power to your water heater, drain it, and then call a professional for inspection and repair.


Hiring a Plumber

A plumber’s job duties include repairing plumbing fixtures, pipes, and water systems. They may repair or replace clogged drains, toilets, and sinks; fix leaky faucets and showerheads; and install new water heaters and dishwashers. Plumbers also inspect and repair sewer lines and septic tanks. Their skills can help them identify problems before they become worse, so the client doesn’t experience more expensive damage.

Plumbing repairs can be complicated and time consuming. A plumber’s hourly rate will vary depending on how experienced they are and the type of repair required. For example, fixing a minor leak may take less time than restoring a faulty water heater or installing a new bathtub.

In addition to their technical knowledge, plumbers must have good customer service skills to answer questions and address complaints. They must also be able to interpret blueprints and plans, and ensure their work meets building codes and regulations. They often work with customers to find solutions that are within their budgets and schedules.

Common plumbing issues that require repair include clogged drains, toilets, showers, and tubs; low water pressure; and leaky faucets and pipes. Some of these problems have easy fixes for homeowners, but others can be dangerous or even life-threatening if not addressed quickly. For example, a clogged toilet can lead to flooding and serious water damage.

Plumbers can also install water filtration systems to improve the quality of household water. These systems can remove contaminants like lead, chlorine, and toxins from drinking water. Some types of filters also reduce the amount of acid in the water, which can prevent damage to pipes and fixtures.

While many people try to fix plumbing issues themselves, it is usually best to leave these jobs to professionals. Inexperienced homeowners can make mistakes that lead to further damage and costly repairs. In addition, attempting to make complex repairs, such as a backed-up sewer line, can be hazardous and could cause further damage to the home’s structure or appliances. It’s also important to remember that if you’re renting your home, it is typically the landlord’s responsibility to pay for plumbing services.


Plumbers install, repair and maintain the pipes that carry water and other liquids to and from fixtures such as sinks, toilets, showers, bathtubs and dishwashers. They also install and repair water heaters. Plumbers usually work in residential and commercial settings. Some plumbers specialize in specific types of plumbing installations, such as gas line installations and repairs. Plumbers must be able to read and interpret blueprints and plans in order to correctly install pipe systems. They may use a variety of tools to perform their job, including pipe cutters, saws, wrenches, soldering equipment and power tools.

Plumbers must be able to work in tight spaces and confined areas such as basements and crawl spaces in order to install and repair pipes. They often spend significant time working on outdoor plumbing systems as well.

Maintenance services offered by plumbers can help property owners save money in the long run. Regular inspections can detect problems like leaks and clogs before they become serious issues that require expensive repairs. Plumbers can also provide advice on how to keep plumbing systems in good condition and running efficiently.

A professional plumber will offer a warranty on his or her work. This is an excellent way to build trust with clients and ensure that customers are satisfied with the quality of service they receive. In addition, a plumber should always be honest with clients about the cost of his or her services. A good plumber will not try to take advantage of a customer by overcharging for routine or emergency services.

Plumbers typically work around the clock, responding to calls for service and performing maintenance duties as needed. They must be able to work independently or with others, and they often travel between different jobsites. They must also be able to work in various weather conditions. Many plumbers are self-employed and may work freelance or on contract for construction companies or homeowners. Other plumbers are members of a union and must follow the rules and regulations set by their organization. A high school diploma or equivalent is required for those who want to become plumbers. There are several ways to gain the necessary skills for this career, including attending a vocational or trade school program and completing an apprenticeship.


A plumbing system is a complex network of pipes, fixtures and other components that carry water, waste products and air throughout your home or business. Plumbers troubleshoot problems with this system to identify the source of the issue and repair it. Their services are essential for a safe and functioning household, office or retail store. Without a properly functioning plumbing system, you could face flooding, water damage and health issues.

Plumbers are skilled professionals who understand the ins and outs of a wide variety of plumbing systems. They can install, maintain and repair everything from toilets and sinks to water heaters and sewage systems. Some plumbers specialize in particular systems, while others offer general maintenance and repairs.

One of the most common reasons to call a plumber is for clogged drains and toilets. These clogs can be caused by hair, grease or other debris that builds up in the pipes over time. A plumber can use a high-powered water jet to clear these clogs and restore proper flow to your plumbing system.

Other common plumbing problems include leaky faucets, dripping taps and water pressure issues. A plumber can fix these problems to prevent further damage and save you money on your utility bills.

If you notice a sudden drop in your water pressure, it may be a sign that your water heater is on its last legs. A plumber can replace your old water heater with a new one to increase your home’s energy efficiency and save you money on your utility bills.

Another important service that plumbers provide is fixing sewer backups and septic tank issues. These can be extremely dangerous for your family if not addressed immediately, as they can cause flooding and mold growth. Plumbers can install backflow valves to protect your home from these issues and repair sewage lines if they are backed up. They also can clean out your septic tank to prevent overflow and remove any harmful bacteria that may be growing inside it.
