That’s why we’re here to make your water heater installation in Wildwood smooth, stress-free, and built to last.


If you’re planning to replace or install a new unit, here’s what you can expect before, during, and after the process, and why choosing a trusted local expert like Castlewood Plumbing makes all the difference.

Key Takeaways

  • Professional installation ensures safe removal of the old unit, proper setup of the new one, and full compliance with Wildwood codes, all handled by licensed experts.
  • Homeowners can expect a smooth, scheduled process beginning with a consultation to choose the right tank or tankless system for their needs and budget.
  • Castlewood Plumbing prepares and protects your home, removes the old heater, installs the new one, and performs full testing and inspection before leaving.
  • Choosing professionals offers benefits such as warranty protection, energy efficiency, quality workmanship, and long-term reliability.
  • Routine maintenance, along with Castlewood Plumbing’s membership perks, helps keep your new water heater running efficiently and lasting for years.


Understanding When It’s Time for a New Water Heater

Before getting into the installation process, it helps to know when a replacement is actually needed. Most traditional water heaters last about 8–12 years. But even before reaching that age, you might start noticing signs that it’s time to upgrade:


  • Water takes longer to heat up
  • Rusty or discolored water
  • Unusual popping or rumbling noises
  • Leaks around the base of the tank
  • Inconsistent hot water supply


If any of these sound familiar, your system may be nearing the end of its life. Instead of waiting for it to fail completely, scheduling a professional water heater installation in Wildwood can save you from sudden breakdowns and costly emergency repairs.


Step 1: Scheduling Your Installation with Castlewood Plumbing

The first step is easy: reach out to Castlewood Plumbing online or by phone at 636-394-6737. Our friendly team will help you set up an appointment that works with your schedule.


During the initial consultation, we’ll ask a few quick questions about your current system and your household’s hot water needs. Whether you prefer a traditional tank model or want to upgrade to an energy-efficient tankless system, we’ll guide you through the options that best suit your home and budget.


Our goal is to make the process as convenient as possible, starting with honest, upfront pricing and clear communication from day one.


Step 2: Preparing Your Home for Installation

Before installation day, there are a few simple things you can do to help things go smoothly. Make sure the area around your current water heater is clear of boxes, tools, or other items. This allows our licensed plumbers to safely access the space and complete the installation efficiently.


If your water heater is located in a basement or utility closet, we’ll take precautions to protect floors and walls from any potential mess. We also ensure that your home stays safe and clean throughout the entire process.


At Castlewood Plumbing, we treat every home with the same care we would our own.


Step 3: Removing the Old Water Heater

Once everything is ready, our technicians will shut off the water and power supply to safely remove your existing unit. If it’s a gas water heater, we’ll disconnect the gas line and venting system following all safety regulations.


This step often includes draining the old tank and safely disposing of it, ensuring no leftover water causes damage or leaks. Proper removal is crucial because it prevents potential issues that could arise from leftover sediment or rust in your plumbing system.


By trusting Castlewood Plumbing, you can be confident that every detail from removal to cleanup is handled correctly and safely.


Step 4: Installing the New Water Heater

Now comes the exciting part: installing your brand-new water heater. Our experienced plumbers will position the new unit, connect the plumbing lines, and ensure all fittings are watertight.


If you’ve chosen a tankless water heater installation in Wildwood, MO, the setup may involve additional steps such as mounting the unit, connecting the gas or electrical lines, and adjusting water flow settings. These systems require precision, and our team has the expertise to ensure optimal performance and safety.


After installation, we thoroughly test the system to confirm that everything is working properly. You’ll have hot water running again before we leave, and we’ll walk you through how to operate your new system.


Step 5: Testing, Inspection, and Clean-Up

Once the new water heater is installed, our team conducts a full inspection. We check for leaks, verify temperature settings, and test the pressure relief valve to ensure everything functions safely.


We’ll also make sure your system complies with all local building and safety codes in Wildwood. Our team prides itself on leaving your space cleaner than when we arrived. When you work with Castlewood Plumbing, you’ll never have to worry about post-installation messes or hidden surprises.


After final testing, we’ll show you how to monitor your system and perform basic maintenance so you can enjoy years of worry-free hot water.

Tank vs. Tankless: Which Is Right for Your Home?

When choosing a new water heater, most homeowners debate between traditional tank models and modern tankless systems. Both have their advantages, and the right choice depends on your household's needs.


Traditional Water Heaters

  • Store hot water in a tank
  • Lower upfront cost
  • Easier to install
  • Ideal for smaller households


Tankless Water Heaters

  • Heat water on demand for an unlimited supply
  • Higher energy efficiency
  • Longer lifespan
  • Perfect for larger families or high usage


During your consultation, Castlewood Plumbing will help you decide which type works best for your home and budget. We’ll also walk you through financing options to make your investment more affordable.


Keeping Your New Water Heater in Top Shape

Once your new unit is installed, a little routine care can go a long way. Here are a few simple maintenance tips to keep your system running efficiently:


  1. Flush the tank once or twice a year to remove sediment buildup.
  2. Inspect the pressure relief valve regularly.
  3. Check for leaks or rust around fittings.
  4. Schedule annual maintenance with Castlewood Plumbing to catch small issues early.


Our Round Table Membership makes it easy to stay on top of maintenance with priority scheduling, discounted rates, and yearly inspections. Regular care not only extends your water heater’s lifespan but also keeps your utility bills low.
