How to Change Tap Washer
A leaky tap has the capacity to cause significant damage to a wide variety of fixtures. Water can affect cabinets, sub-floors and walls. The build up of mould is another key problem that can result in considerable damage around the house. If left unresolved, the leaks will eventually contribute to a decrease in the resale value of the home. Mould and mildew are known to cause health problems for occupants, particularly individuals suffering from allergies.
In many cases, a worn O-ring can trigger the leaks. If neglected, the issue can worsen. Depending on the cause of the problem, plumbers will replace the worn parts or grind the valve seat to ensure an optimal seal.
Homeowners can learn how to change tap washer to prevent the problem from damaging fixtures in the house or wasting water. However, in most cases, leaks are not caused by the washer. Instead, the problem is triggered by the valve seat, which is the component that the washer rests on when the water is not running. The brass of the valve seat is gradually eroded due to the considerable pressure, which acts on the components.
The pressure results in the formation of small canals on the valve seat. This enables the water to by-pass the washer and start dripping.
Step-by-step guide on How to Change Tap Washer
Repairing the valve seat
- The first step involves turning off the water before placing the plug in the hole.
- Once the first step is complete, it is necessary to remove the tap indicator covers using a screwdriver. This is aimed at exposing the top screw. The majority of modern taps come with hot (red) and cold (blue) indicators. The screw is typically located underneath the covers.
- The next step entails releasing the valve and covering the tap with a cloth to avoid scratching the metal. The tap must sit firmly in position to avoid loosening the water connection underneath.
Grinding the valve seat
- Oftentimes, the leaking is caused by the small canals, which are eroded on the seat’s metal.
- The canals can be removed using a valve seat grinding tool to achieve flat and smooth surfaces.
- It is important to select the ideal size serrated cutter that fits snugly on the opening.
- The same applies to the thread, which is used to tighten the threads that hold the valve.
- Once the grinder components are fitted properly, it is time to grind the seat.
- Experienced plumbers usually make a full revolution while twisting and pushing the grinder down. The process can be completed by performing a few revolutions with the aim to make the seat smooth.
- It is vital to verify whether the seat is smooth by inserting a finger and checking for indents.
- When the valve seat is smooth, replace the valve, tap indicator covers and other components before turning on the water.
