1. Ignoring Local Codes and Permit Requirements
One of the most common mistakes many homeowners make is skipping the necessary permits or not adhering to local codes. Water heater installation must meet specific safety standards and building codes set by the city.
These regulations are in place to prevent risks such as gas leaks, water damage, or electrical hazards. Hiring a professional plumber from a full-service plumbing company ensures the job is up to code and properly inspected.
2. Incorrect Sizing of the Water Heater
Choosing the wrong size water heater for your house can lead to an inadequate hot water supply or unnecessary energy consumption. Whether you’re considering a tankless system or a traditional water heater, proper sizing is crucial.
A system that’s too small won’t meet your household’s demands, while one that’s too large wastes energy and money. Consulting a local plumber who understands your home’s flow rate and plumbing system can help determine the most efficient option.
3. Poor Ventilation Setup
For gas-powered water heaters, improper ventilation is a serious safety concern. Faulty venting can cause dangerous carbon monoxide to build up inside the home. This mistake not only jeopardizes your family’s health but can also void your warranty.
A professional will make sure your equipment is ventilated according to local codes, using the correct materials and angles to ensure safe operation.
4. DIY Without the Right Tools or Experience
While some homeowners try to save on cost by doing it themselves, improper installation due to a lack of tools or expertise can lead to major plumbing problems. Without the right tools, fittings may be left loose, fixtures misaligned, or water lines improperly connected.
These mistakes can cause leaks, flooding, or even structural water damage. It’s far more economical in the long run to hire a plumbing company that provides quality work and guarantees the job is done right.
5. Skipping Water Line and Valve Checks
Failing to inspect pipes, valves, and connections during a water heater installation can result in leaks and plumbing issues. A good professional plumber will inspect all existing plumbing for signs of wear and recommend replacements if needed.
It’s also smart to replace older shut-off valves and ensure pressure relief valves are functioning correctly for added safety and efficiency.
6. Choosing the Wrong Type of Water Heater
Not all water heaters are created equal. Many homeowners are switching to tankless water heaters to save money and reduce energy usage. However, installing a tankless system requires specific infrastructure and planning.
If your current plumbing system isn’t designed to handle it, you’ll face additional repairs or complications. Speak with a plumbing company to determine whether a tank or tankless water heater best suits your needs.
7. Not Leveling the Unit Properly
A tilted water heater may seem like a small issue, but over time, it can put stress on pipes, fittings, and joints. It may even affect the heater’s performance and lifespan.
Ensuring the unit is level and securely anchored is an essential part of the installation process. It may require adjustments to the flooring or platform it’s placed on.
8. Neglecting Regular Maintenance After Installation
Water heater installation is not a one-and-done task. Without regular maintenance, sediment builds up in the tank, reducing efficiency and potentially damaging the system.
Maintenance includes flushing the tank, checking anode rods, and inspecting connections. A full-service plumbing company in Maryville can schedule annual checks to keep your system running efficiently and extend its life.
9. Forgetting to Insulate Pipes and the Tank
Failing to insulate water lines and the tank itself leads to heat loss and increased energy bills. This is especially true during colder months in Maryville.
Simple insulation can help save money on heating costs while protecting your pipes from freezing.
10. Overlooking the Importance of Professional Help
Many think that hiring a professional plumber is an unnecessary cost, but the reality is that expert help ensures your water heater is properly installed and your plumbing remains intact.
A licensed plumbing company will also back their services with warranties and even offer a free quote, so you know what to expect upfront.
