Washer for a Mixer Tap

Before we start the method to change a washer on a mixer tap, let us have a look at the types of washers used in the standard mixer taps. The following are the common washer types:

Fiber Washers: These washers are complicated but more manageable to compress than their nylon and rubber counterparts making them less vulnerable to water exposure.

Nylon Washers: These washers are reliable, long-lasting, lightweight, and cost-effective with low surface friction because of internal lubrication.

Polythene or Rubber Washers: Rubber washers are malleable and preferable for taps made of hard material. These washers are softer than those made of nylon. Extensive water exposure causes cracks in these washers.

Ceramic disc cartridges: These are far more long-lasting than rubber washers but are pronto cracks and leaks.
