A Guide to Reseating a Tap

reseating-tap

If you have replaced the tap washers as described in A Guide to Fixing a Leaking Tap and the tap continues to leak, it may need to be re-seated. A licenced plumber can reseat a tap.

The following process describes how this is achieved.

Reseating merely resurfaces your tap; it removes the calcium and corrosion build-up so the washer has the tightest seal.

You may need to use A Guide to Fixing a Leaking Tap as a reference.

 

Tools

  1. Tap re-seating tool.
  2. The tools used in A Guide to Fixing a Leaking Tap.

Method
The tap is disassembled as described in A Guide to Fixing a Leaking Tap.

Step 1 – Insert the tap re-seating tool into the tap body and screw it in. The conical shape of the tool will ensure that it should centre vertically in to the tap body.

Step 2Note: Do not screw it in hard as you will damage the seat. Using a firm downward pressure on the tool rotate it in a clockwise direction two or three turns or until the centre has no restriction.

Step 3 – Unscrew the reseating tool and check to see if the seat is shiny.

Step 4 – If some of the seat is still dull, repeat Steps 1 – 3 and check again.

Step 5 – If the seat is badly damaged it may take several times to clean it totally. If you are in any doubt you should call a licenced plumber.

Step 6 – Flush the metal filings out of the tap body and reassemble the tap as described in A Guide to Fixing a Leaking Tap.

Note: An alternative to the above method is to replace the seat of the tap by purchasing a nylon seat that comes with a jumper and washer from your local hardware store.

The new nylon seat is placed over the old seat and the jumper and washer fitted in place of the old ones. The tap should then be reassembled and closed as fully as possible; this will ensure the new seat has been fixed in position correctly.

  1. worthwhile info, same as my hardware store said …
    but they forgot to mention that some taps – like our bathroom vanity taps – are extra long, and the re-seating tool cannot reach

  2. All good advice. I had lot of trouble with my old dripping taps and in the end bought reseating kits. You don’t need to use the tool, just pop them in and screw in the tap. Saves a lot of stress and is like getting a new tap. GThan ks guys.

  3. My bathroom basin has a single spout – two taps. There is a constant drip. I have removed both taps (H&C). I have replaced the washers (but not the O-rings yet) and reseated both, all before reading your webpages. The tap(s) still leak.
    When reseating the hot tap, the seat became smooth and shiny quite quickly. The cold tap seat was shiny but felt a bit “bumpy” as I turned the reseating tool. I was loathe to keep going until it was smooth in case I “ate” too much off. Any suggestions?

  4. The flange is like stuck on their, can not take of the flange to be able to fix the leaking tap
    Because there is no way to get it off.
