Why your hot water tap keeps sputtering: 5 shocking reasons

A spluttering hot water tap is not just an annoyance; it can also be a sign of underlying plumbing issues. Understanding the causes of this problem is crucial for finding an effective solution. In this comprehensive guide, we will explore various reasons why your hot water tap may be spluttering and provide practical solutions to address each cause.

Causes of Hot Water Tap Spluttering

1. Air in the Water Lines

Trapped air in the water lines can cause the hot water to sputter as it escapes. This commonly occurs after plumbing work, such as installing a new faucet or replacing pipes.

2. Faulty Pressure Reducing Valve (PRV)

The PRV regulates the water pressure in your home. If it malfunctions, it can lead to excessive water pressure, causing the hot water to sputter.

3. Clogged Aerator

The aerator is a small screen attached to the faucet spout that mixes air with water to create a steady stream. When it becomes clogged with debris, it can restrict the flow of water and cause spluttering.

4. Worn-Out Washer

The washer is a rubber seal that prevents water from leaking from the faucet handle. Over time, the washer can wear out and allow water to escape, creating a sputtering sound.

5. Corroded Pipes

Corrosion inside the pipes can cause mineral deposits to build up, narrowing the pipes and restricting water flow. This can result in spluttering and reduced water pressure.

6. Oversized Water Heater

An oversized water heater can produce more hot water than your plumbing system can handle, leading to excessive pressure and spluttering.

7. Cross-Contamination of Water Lines

In some cases, the hot and cold water lines may be cross-connected, allowing cold water to mix with hot water. This can cause the hot water to sputter and fluctuate in temperature.

Troubleshooting and Solutions

1. Release Trapped Air

Turn off the hot water supply and open the hot water faucet. Let the water run for a few minutes to release any trapped air.

2. Adjust the Pressure Reducing Valve

If the PRV is malfunctioning, it may need to be replaced. Consult a licensed plumber to adjust or replace the PRV.

3. Clean the Aerator

Unscrew the aerator from the faucet spout and clean it with a brush or soak it in vinegar to remove any debris.

4. Replace the Washer

Turn off the water supply and remove the faucet handle. Replace the old washer with a new one that matches the size and type of your faucet.

5. Flush the Pipes

If you suspect corrosion in the pipes, flush them by running hot water through all the faucets in your home for several minutes. This can help remove mineral deposits.

6. Consider a Smaller Water Heater

If your water heater is oversized, consider replacing it with a smaller model that is more suitable for your plumbing system.

7. Call a Plumber

If none of the above solutions resolve the spluttering issue, it is advisable to call a licensed plumber. They can diagnose the problem and recommend the appropriate repair or replacement.

Recommendations: Unclogging the Mystery

By understanding the various causes of hot water tap spluttering and following the troubleshooting steps outlined above, you can effectively address this common plumbing issue. Remember that if the problem persists or is beyond your comfort level, do not hesitate to seek professional assistance from a qualified plumber.
