Complete Water Heater Guide: Installation to Repair
Water heaters are a critical part of your home infrastructure, and over the course of our decades of experience, it's one of the things that homeowners have the most questions about. We've put together this guide in the hopes of helping to answer some common questions and concerns about water heaters, so here it is, our complete water heater plumbing guide, covering everything from installation to repair.
Water Heater Types
Water heaters can be broadly categorized into three types: gas, electric, and tankless.
Gas Water Heaters: These water heaters have gas burners beneath the water tank. They heat water at a much faster rate as compared to the electric units and can operate during power blackouts.
Electric Water Heaters: These are operated with electricity. As a result, the heating elements within the tank produce heat for the water. They can be expensive if electricity costs are high,
Tankless Water Heaters: Also known as flash water heaters, these do not store hot water. Instead, they heat water on demand, but they have a slightly higher upfront cost and sometimes a whole plumbing upgrade.
Gas Water Heaters are considered in the regions where the gas is cheaper than electricity. They have to be vented outside the building.
Electric Water Heaters are what one can opt for if the home does not have a gas line already. They are also considered more secure as they do not burn fuel in order to maintain the heating.
Tankless water heaters are wonderful space-saving options because they are suitable not only for homes with limited space but for families whose hot water needs vary. They are instant and no energy is wasted at all to keep water hot while there is no use for it.
What’s the Difference Between a Water Heater and a Boiler?
Key Components of a Water Heater
Understanding the key components of your water heater can help in troubleshooting and maintenance.
Here’s some water heater plumbing advice on what to look for:
Thermostat: Regulates the water temperature in the tank so it stays within the safe and efficient range.
Heating Element (Electric)/Gas Burner (Gas): Heater for the water. Electric models usually have one or two components.
Dip Tube: It then travels down to the bottom of the tank where it is heated.
Drain Valve: At the bottom of the tank, it is installed for draining the tank, for maintenance or diagnosis.
Pressure Relief Valve: Keeps the water heater tank pressure from becoming too high.
Anode Rod: A sacrificial rod that helps to reduce the corrosion process that occurs inside the tank.
Pre-Installation Considerations
Before the installation of the new water heater, several parameters should be analyzed, and the installation process should be smooth.
Selecting the Right Water Heater
Capacity: Analyze your household water consumption. Generally, a bigger family needs an even larger water heater with a larger tank (40-60 gallons) to make sure there is a constant supply of hot water.
Energy Efficiency: Consider units that feature high energy efficiency ratings to lower operational expenses. Try models with the Energy Star label.
Space Requirements: Guarantee the space is sufficient to install the water heater. Tankless water heaters are more compact and are easy to install in tight spaces.
Fuel Type: Choose between gas or electricity depending on how accessible and economical these two sources are in your locality. It is necessary to keep in mind that the gas models usually need venting.

Required Tools and Materials
Tools: Adjustable wrenches, pipe wrenches, screwdrivers, tape measure, tubing cutter, soldering torch.
Materials: Pipes and fittings, Teflon tape, solder, pipe insulation, venting materials for the gas heaters, and a discharge pipe for the temperature-pressure relief valve.
Safety Measures
Turn Off Power: Remember to switch the power supply (electricity or gas) off before starting the process to prevent accidents. This is crucial water heater plumbing advice for your safety.
Check for Leaks: When done connecting the water heater, check all connections for leaks using soapy water.
Proper Ventilation: Venting of gas water heaters should be done correctly to prevent carbon monoxide accumulation.
Installation Process
Step by Step Installation Instructions for Tank-Type Water Heaters
Remove the Old Heater: Switch off the power socket and allow the old unit to drain before detaching and removing it.
Prepare the Area: Make the area clean and flat. Place a drip pan if such is required by local codes.
Install New Water Connections: Link the cold water supply to the dip tube and the hot water line to the water heater’s hot outlet using dielectric unions if corrosion-resistant fittings are unavailable.
Attach the Discharge Pipe: Connect the temperature-pressure relief valve and rout the discharge pipe, making sure it is discharged to a safe place.
Fill the Tank: Open the supply of cold water to fill the tank. Check for leaks.
Connect to Power Supply: For electric heaters connect the wires to the corresponding terminals. For the gas heaters, make the gas connection and check for leaks with soapy water.
Turn On the Water Heater: Follow the manufacturer's instructions to light the pilot (if it is gas) or turn on the circuit (if it is electric).
Adjustments for Tankless Models
Sizing: Make sure that the model you select is big enough for the flow rate requirements of your house.
Installation Location: Closer to the point of use they can be installed. Strengthen the walls for mounting.
Electrical Requirements: Ascertain that the electric systems meet the demands of electric tankless models.
Venting for Gas Models: Follow specified venting recommendations that may be drastically different from those of tank configurations.
Initial Setup and Testing
Initial Start-up: Carefully follow the instructions provided by the manufacturer and start.
Test Hot Water: Turn on the tap to find out if the hot water is available or not and adjust the thermostat accordingly.
Safety Check: Make sure that all safety features ever installed are in perfect condition.
Maintenance Tips
Proper water heater maintenance will enable the unit to provide an uninterrupted hot water supply, increase its longevity, and thus minimize repair and replacement costs. Furthermore, to avoid incurring extra costs and losing supplies of hot water, you may find it useful to get used to knowing the way your water heater functions. This will enable you to detect and deal with problems early enough and hence maintain a stable supply of hot water.
Routine maintenance therefore plays a very important role in achieving maximum efficiency and lifespan of your water heater. Here’s some water heater plumbing advice on key maintenance tasks and their frequency
Regular Maintenance Schedule
Sediment deposits can reduce the heater's productivity and destroy the tank. Drain the tank at least once a year to take out sediment, according to the guidelines provided by the manufacturer.
The anode rod protects the tank from corrosion. Every 1-3 years, check it and replace it if more than 6 inches of the core steel wire is exposed or the rod is coated with calcium.
Make sure that it is working properly by pulling the lever and letting it snap back into place. Water should flow and stop when the lever is lifted. Perform this test annually.
In the case of electric water heaters, check the heating elements every two to three years to see that they are not burned out or have sediment on them.
Inspect the tank and its connections regularly and look for any leaks, which may be a sign of needed repairs or replacements.
DIY Maintenance Tips
Insulating the Pipes and Tank: Decrease the heat loss by insulating both the hot and cold pipes and the tank. This is a great way, especially for older units.
Adjusting the Temperature: To conserve energy and prevent scalding, as well as to decrease mineral buildup and corrosion, set the water heater temperature to 120 degrees Fahrenheit.
Cleaning Air Intakes: For gas water heaters, make sure the air intakes are always clean and free from any blockages to ensure safe and effective operation.
Troubleshooting Common Issues
Understanding how to identify and fix common water heater problems can save you time and money. Here’s how to recognize some frequent issues:
The appearance of the water around the heater could be a sign of a tank, valve, or piping connection leak.
The popping or rumbling noises usually indicate the accumulation of sediment, which makes the water heat up.
Temperature inconsistency may occur because of faulty thermostats or heating element functions.
Simple Fixes
Safely follow the manufacturer’s directions while re-lighting the pilot on a gas water heater.
If the breaker has tripped, reset it and watch the heater for other electrical problems.
To correct noise from sediment, drain and flush the tank. It includes shutting off the power, hooking up a hose to the drain valve, and letting the whole tank drain until it is clear.
For heating element or thermostat issues, turn off the power, drain the tank, and replace the broken parts. Make compatibility with your heater’s model a priority.
