How To Fix A Leaking Tap

Did you know, if your leaking tap fills a 200mL glass in 15 minutes, it will waste 680 Litres in a month and 8,000 Litres in a year?

If your tap leaks when it is turned off, it means the washer attached to the jumper valve needs replacing. Now don’t fret, this is an easy DIY job and can be completed with these simple steps provided by your local Jim’s Plumbing expert. Whilst you’re replacing your washer, it’s worthwhile replacing the O-ring aswell. This will prevent water from flowing between the tap body or out from under the cover plate. Either way, the tap will need to be dismantled, so it’s worth replacing both while you’re at it.

Step 1

You will need to gather some supplies to kick off your repair job. These items can be found at any reputable hardware store.

  • Tap washer repair kit

or individually

  • 12mm (1/2”) washers (these are most commonly used inside the home)
  • O-ring
  • Jumper valve
  • Reseating kit (if necessary)
  • Wrench /spanner or tap spanner set
  • Multi-grips (if necessary)
  • Screwdriver
  • Tap lubricant
  • Cloth

Step 2

The first thing you should do is turn off your main water supply. Your main water supply will usually be located in your front yard or depending on your accommodation, it could be in the bathroom or laundry. Following this, you can begin to deconstruct your tap. It’s best to turn on the tap first, this will release any water left in the pipe. We recommend putting a plug in the sink to eliminate the possibility of any small parts falling down your drain and causing yet another plumbing disaster.

Step 3

Gently remove the hot or cold sign on the top of your tap and take the taps cover off using your spanner. Next, unscrew the bonnet and completely remove the headgear. This will reveal the body washer, O-Ring and jumper valve. which should fall out. If you have chrome tapware, place a cloth over the cover to prevent scratches.

Step 4

Install your new body washer, O-ring and jumper valve. It’s always best to apply a tap lubricant to the valve. This provides better sealing and smoother tap operation. Following this, you can refit the tap bonnet and spindle. Do not over tighten the nuts.

Step 5

Put your tap back together, make sure it is off and then turn your water main back on. Sit back, relax, admire your job and rest assured knowing that you’re not wasting a drop.

Please Note

If your tap is still leaking, it will more than likely need to be re-seated. A reseating kit can be purchased from any reputable hardware store.
