How to Increase Water Flow in a Tap?

Published in Plumbing Maintenance 3 mins read

Increasing water flow in a tap can be achieved through various methods, ranging from simple fixes to more involved solutions. The best approach depends on the underlying cause of the low flow.

Here's a breakdown of potential causes and solutions:

Potential Causes and Solutions

  • Aerator Issues:

    • Problem: The aerator, located at the tap's tip, mixes air with water. It can become clogged with sediment and debris, restricting flow.
    • Solution: Unscrew the aerator. Disassemble it and clean all parts thoroughly, removing any visible buildup. Rinse well and reassemble. If damaged, replace the aerator.
  • Clogged Cartridge:

    • Problem: In single-handle faucets, the cartridge controls water flow and temperature. Mineral deposits and debris can accumulate within the cartridge, impeding water flow.
    • Solution: Turn off the water supply. Disassemble the faucet to access the cartridge. Clean the cartridge thoroughly or replace it with a new one if cleaning doesn't resolve the issue.
  • Low Water Pressure:

    • Problem: Low water pressure throughout your home will naturally result in reduced flow from all taps.
    • Solution: Contact your water company to inquire about the general water pressure in your area. If the pressure is low for everyone, they may be able to address the issue. If the problem is isolated to your home, consider installing a pressure booster pump.
  • Kinked or Damaged Supply Lines:

    • Problem: The pipes supplying water to your tap can become kinked or damaged, restricting water flow.
    • Solution: Inspect the supply lines under the sink. Straighten any kinks. If the lines are damaged, replace them. Use flexible supply lines for easier installation and to avoid future kinks.
  • Partially Closed Shut-Off Valves:

    • Problem: The shut-off valves located under the sink may not be fully open, restricting water flow.
    • Solution: Ensure that both the hot and cold water shut-off valves are completely open.
  • Corroded or Blocked Pipes:

    • Problem: Over time, pipes can corrode or become blocked with mineral deposits, reducing water flow.
    • Solution: This is a more complex issue. Depending on the extent of the problem, you may need to consult a plumber to clean or replace the affected pipes.
  • Electric Shower Slow Flow: (As referenced in the provided text excerpt)

    • Problem: A slow flow of water into an electric shower can cause it to function poorly.
    • Solution: Increasing the incoming water pressure to the electric shower unit might solve the issue. Consider a pump like a TapBoost (mentioned in the video title) to increase water pressure going to the shower. Ensure compatibility and proper installation.

Considerations

  • Before undertaking any repairs, always turn off the water supply to the tap to prevent flooding.
  • If you are uncomfortable performing plumbing repairs, consult a qualified plumber.
  • Regular maintenance, such as cleaning aerators, can help prevent flow issues.
