Unveiling The Mystery: Why Does Your Mixer Tap Drip Uncontrollably?

A dripping mixer tap is a common household annoyance that can waste water and increase your utility bills. Understanding the causes behind this persistent problem is the first step towards finding a solution. Here are some of the most frequent reasons why your mixer tap may be dripping:

Worn-Out Washer

The washer is a small rubber or plastic disc that sits against the valve seat to create a seal and prevent water flow. Over time, the washer can wear out, become brittle, or develop cracks, causing water to leak past it.

Damaged Valve Seat

The valve seat is the surface against which the washer seals. If the valve seat is scratched, pitted, or corroded, it can prevent the washer from forming a tight seal, resulting in a drip.

Loose Handle

A loose handle can cause the tap’s internal components to shift, compromising the seal between the washer and the valve seat. This can lead to a slow but persistent drip.

Faulty Cartridge

Mixer taps with cartridge-based valves may experience dripping if the cartridge is damaged or worn. The cartridge is a self-contained unit that controls water flow and mixing. A faulty cartridge can allow water to bypass the seals and cause a drip.

High Water Pressure

Excessive water pressure can put strain on the tap’s components, causing the washer to leak or the valve seat to become damaged. Installing a pressure-reducing valve can help mitigate this issue.

Debris or Mineral Buildup

Mineral deposits or other debris can accumulate on the washer or valve seat, preventing a proper seal. This can result in a slow drip or intermittent dripping.

Corrosion

Corrosion can damage the tap’s internal components, including the washer, valve seat, and cartridge. This can weaken the seal and lead to dripping.

How to Fix a Dripping Mixer Tap

Depending on the cause of the drip, there are several methods to repair a dripping mixer tap:

Replace the Washer

Replacing the washer is a quick and inexpensive fix for a worn-out washer. Simply remove the handle, unscrew the cartridge (if applicable), and replace the old washer with a new one.

Repair or Replace the Valve Seat

If the valve seat is damaged, you may be able to repair it using a valve seat repair tool. However, if the damage is severe, it may be necessary to replace the entire tap.

Tighten the Handle

If the handle is loose, simply tighten it using a wrench or pliers. Ensure that you do not overtighten the handle, as this can damage the tap.

Replace the Cartridge

If the cartridge is faulty, it will need to be replaced. Remove the handle, unscrew the cartridge, and install a new one.

Reduce Water Pressure

Installing a pressure-reducing valve can help prevent excessive water pressure from damaging the tap’s components.

Clean Debris or Mineral Buildup

Use a mild cleaning solution and a soft cloth to remove any debris or mineral buildup from the washer and valve seat.

Address Corrosion

If corrosion is the cause of the drip, you may need to replace the affected components or the entire tap.
