What To Know

  • The aerator is a small device located at the tip of the faucet that mixes air with water to create a more forceful stream.
  • Corrosion in the pipes that supply hot water to the tap can cause a buildup of scale and rust, which can narrow the pipe diameter and restrict water flow.
  • Yes, a water softener can reduce the amount of minerals in the water, which can help prevent clogging in the aerator and other plumbing fixtures.

When your hot water tap trickles instead of providing a steady stream, it can be a frustrating and inconvenient problem. Understanding the underlying causes can help you resolve the issue efficiently. In this comprehensive guide, we’ll explore the reasons why your hot water tap may be just trickling and provide step-by-step solutions to restore its full flow.

Clogged Aerator

The aerator is a small device located at the tip of the faucet that mixes air with water to create a more forceful stream. Over time, mineral deposits and debris can accumulate in the aerator, restricting water flow.

Solution:

1. Unscrew the aerator using a wrench or pliers.
2. Soak the aerator in vinegar or a commercial cleaning solution for 30 minutes.
3. Use a brush or toothpick to remove any visible debris.
4. Rinse the aerator thoroughly and reattach it to the faucet.

Faulty Washer

The washer is a rubber seal that creates a watertight seal between the faucet stem and the body. A worn or damaged washer can allow water to leak out, resulting in a reduced flow from the tap.

Solution:

1. Turn off the water supply to the faucet.
2. Remove the handle and stem assembly.
3. Replace the old washer with a new one of the same size and type.
4. Reassemble the faucet and turn the water supply back on.

Corroded Pipes

Corrosion in the pipes that supply hot water to the tap can cause a buildup of scale and rust, which can narrow the pipe diameter and restrict water flow.

Solution:

1. If the pipes are accessible, you can use a commercial pipe cleaner to remove corrosion.
2. If the pipes are hidden behind walls or floors, consider contacting a plumber for professional cleaning or replacement.

Low Water Pressure

Inadequate water pressure can cause all the taps in your home to trickle, not just the hot water tap. This can be caused by a variety of factors, including:

  • A clogged or damaged pressure regulator
  • A leak in the water supply line
  • A problem with the city’s water supply

Solution:

1. Check the water pressure regulator and replace it if necessary.
2. Inspect the water supply line for leaks and repair or replace any damaged sections.
3. Contact your water utility company to inquire about any issues with the water supply.

Hot Water Heater Issues

A malfunctioning hot water heater can also cause a trickle from the hot water tap. Common problems include:

  • A faulty heating element
  • A broken thermostat
  • A buildup of sediment in the tank

Solution:

1. Contact a licensed plumber to diagnose and repair any issues with the hot water heater.
2. Regularly flush the hot water heater to remove sediment and extend its lifespan.

Water Valve Restrictions

Water valves installed under the sink or behind the faucet can restrict water flow if they are not fully open.

Solution:

1. Locate the water valves and turn them fully counterclockwise to open them.
2. If the valves are old or damaged, replace them with new ones.

Other Causes

In rare cases, other factors can cause a hot water tap to trickle, such as:

  • A cross-connection between the hot and cold water lines
  • A faulty mixing valve
  • A problem with the plumbing system’s design

Solution:

1. Contact a qualified plumber to investigate and resolve these complex issues.

Wrapping Up

If your hot water tap is just trickling, don’t despair. By following the troubleshooting steps outlined above, you can identify and fix the problem yourself in most cases. However, if the issue persists or is beyond your comfort level, don’t hesitate to contact a licensed plumber for assistance.

Information You Need to Know

Q: Why does my hot water tap trickle at night but not during the day?

A: This could indicate a drop in water pressure at night, such as when everyone in your neighborhood is using water at the same time.

Q: Can I use a water softener to prevent a buildup of mineral deposits in the aerator?

A: Yes, a water softener can reduce the amount of minerals in the water, which can help prevent clogging in the aerator and other plumbing fixtures.

Q: How often should I replace the washer in my faucet?

A: The frequency will vary depending on water quality and usage. As a general rule, it’s recommended to replace the washer every 2-5 years.
