Can I Drain It Myself, or Need a Plumber?

Maintaining your water heater is essential for ensuring consistent hot water, energy efficiency, and a longer lifespan for your system. Many homeowners face a common dilemma: can I drain it myself, or need a plumber? This question is particularly important if you want to avoid costly repairs caused by sediment buildup in your tank. At MileHi HVAC, we help homeowners in Denver make informed decisions about water heater maintenance, including electric water heater installation in Denver.

In this article, we’ll break down when you can handle draining your water heater yourself, when it’s safer to call a professional, and the key steps involved in the process.

Why Draining Your Water Heater Matters

Over time, minerals and sediment from hard water accumulate at the bottom of your water heater. This buildup can:

• Reduce heating efficiency

  
  

• Increase energy bills

• Shorten the lifespan of the water heater

• Cause strange noises like popping or banging

Regular maintenance, including draining, prevents these problems and keeps your hot water supply reliable. Knowing whether to do it yourself or hire a plumber can save time, money, and potential headaches.

DIY vs Plumber: Can I Drain It Myself?

Whether you choose to drain it yourself or call a plumber depends on several factors. Here’s a breakdown:

When You Can Drain It Yourself

If you’re comfortable with basic home maintenance, have the right tools, and your water heater is easily accessible, you may consider a DIY approach. Draining your water heater yourself is feasible if:

• You have standard tools like a garden hose and bucket

• You can safely turn off the power or gas supply

• You can attach a hose to the drain valve and direct water to a safe drainage area

When to Call a Plumber

Calling a professional plumber is the safer choice if:

• Your water heater is hard to access or located in a tight space

• You notice leaks, rust, or corrosion on the tank

• You’re unsure how to handle electrical or gas components

• You want a complete maintenance check while draining

Professional plumbers can drain your tank safely, check the heating elements, and ensure no damage occurs during the process. This is especially helpful for older units or tanks that haven’t been drained in years.

Step-by-Step: How to Drain It Yourself

If you decide to take the DIY route, follow these steps carefully. Safety is the top priority.

Tools Needed

• Garden hose

• Bucket or floor drain

• Adjustable wrench

• Towels for spills

Step 1: Turn Off the Power or Gas

For electric heaters, turn off the circuit breaker. For gas heaters, switch off the pilot light. Never drain a water heater while it’s running, as it can cause serious damage.

Step 2: Let the Water Cool

Hot water can cause burns. Allow your water heater to cool for at least 1–2 hours before draining.

Step 3: Connect a Hose

Attach a garden hose to the drain valve at the bottom of the tank. Run the hose to a safe drainage area, like a floor drain, bathtub, or outside.

Step 4: Open the Drain Valve

Open the valve slowly to release water. Opening a hot water tap in your home helps prevent a vacuum and ensures smoother drainage.

Step 5: Flush Out Sediment

Once the tank is empty, briefly open the cold water supply to flush remaining sediment. Repeat until the water runs clear.

Step 6: Close and Refill

Close the drain valve, remove the hose, and refill the tank. Turn the power or gas back on and check for proper operation.

Common DIY Mistakes to Avoid

Even if you’re confident, homeowners often make these mistakes:

• Draining a hot water heater without turning off the power

• Failing to attach the hose properly, causing water damage

• Not flushing the remaining sediment completely

• Ignoring leaks or rust signs that need professional attention

Avoiding these mistakes ensures your DIY efforts save time and extend the life of your water heater.

Pros and Cons of Draining Yourself vs Hiring a Plumber

DIY Drain: Draining your water heater yourself can save money, as it has a low cost. However, it takes personal time and carries a higher risk of errors. Inspections are limited, so potential issues may go unnoticed.

Plumber Drain: Hiring a professional plumber is quicker and more efficient. While it comes with a higher upfront cost, the risk of mistakes is low. A plumber also performs a full system inspection, ensuring your water heater is safe and functioning properly.
