Reseating a tap can be a bit daunting, but with a bit of information and the right tool, it too can be a simple repair job.

The first step, as with most plumbing jobs, is to make sure the mains supply is turned off!

Once that is out of the way, it is time to remove the tap fixtures, and the tap body. If you are unsure how to do this then please check the following link how to repair a leaking tap, as we have covered it previously in this guide. Make sure the tap valve is out also. You might need a pair of pliers if you can't grip it with your fingers.

Now we need a torch(flashlight) to inspect the tap housing, and you will need it during the reseating process.

Insert a tap reseater (pictured) in place of the removed tap body, and screw the cone section in place.

Then adjust the depth by turning the knurled nut so the cutting blade meets the seat, but is still able to turn freely.

Hold the adjustable section (that's the section with the knurled nut), and turn the T bar handle in a clockwise direction with a slight downward pressure. Do not put too much pressure as the cutting blade is very sharp and will dig in.

Turn the T bar once or twice then remove and inspect with the flashlight. You might need to repeat the same procedure a few times depending on how damaged the seat is.

It is best to take your time and do one or two turns then inspect, rather than do too many and then need a plumber!

Once you are happy the seat is flat and there are no signs of notches or grooves, you can re assemble the tap. At this point it may pay to inspect the tap valve, body washer and o ring. If worn then replace also.
