How Plumbers Flush Water Heaters

When you call a plumber like Butler Heating, Air Conditioning & Plumbing to flush the water heater tank, the service might take one or two hours. The short wait is worth it, especially if you’d like to save on utility bills, enjoy fresh water, and have hot, relaxing showers.

Here’s how the services go step by step:

#1 Getting the Workspace Ready for the Task

First, your plumber prepares their workspace near your water heater, ensuring the area is organized and clutter-free. Usually, they’ll bring along the following essential tools:

• Wrenches or screwdrivers
• A bucket
• A garden hose
• An acidic cleaning solution

Next, they’ll shut off the power supply by closing the fuel valve or cutting electricity to the appliance. Safety precautions prevent surprise fuel leaks and electrical shocks. 

#2 Emptying the Old Water Supply

Knowing how to drain hot water heaters starts with a wrench or screwdriver to open the water heater drain valve so that the tank can empty. The plumber will often attach a garden hose to direct the water flow away from the appliance and safely out of the building. If this isn’t possible, they’ll empty the water into the bucket and dump it. 

Opening the hot water taps quickens the emptying process. 

#3 Rinsing the Tank With Freshwater

Once the tank is empty, your plumber connects the water hose to a spigot and refills it with fresh water. They may aim the hose head at mineral formations to loosen and dislodge them. 

This spray often eliminates most of the sediment. However, if some mineral buildup still clings to the tank interior, the plumber will move to the next step.

#4 Adding a Solution To Break Down Tough Deposits

Part of understanding how to drain hot water heaters includes choosing a suitable solution to get at the buildup inside of it. Typically, your plumber will mix white vinegar with fresh water during this sediment-removal step. 

Your plumber swishes the vinegar and water around so it hits all sides of the tank. After it soaks for a while, the remaining buildup readily falls away. The plumber empties the tank again to get out these bits and pieces.

#5 Refilling and Testing the Appliance

Your plumber will refill the tank one last time to rinse out any remaining buildup that might lurk at the bottom. Then, they can close the drain valve and reconnect the fuel or electrical supply. The refilling and reheating cycle may take up to an hour. 

Water heaters with smaller tanks may only need 20 minutes to finish refilling. After this, your plumber tackles the final step – testing – to guarantee hot water and a perfectly clean tank. 

What Else Happens During Water Heater Maintenance?

While tank flushing takes up the bulk of the service, your plumber will often make other adjustments, such as:

• Cleaning supply and drain valves
• Checking for and replacing worn rubber seals
• Ensuring secure electrical or fuel connections
• Adjusting the thermostat

These minor tasks make your appliance safer and more predictable.
