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