Hi @Krusty,

Were the sleeves you used something like Kinetic 12mm Push In Tap Seats? This is what you would use if you're having difficulty reaming the tap seat flat. When you say the tap seats have been over-reamed it sounds like they are flat, but the washer no longer makes contact as the seat is too deep. If this is the case, you could try installing a HydroSeal Tap Seat Replacement Kit as this kit has threaded seats.

I believe installing ceramic disc tap spindles could solve this issue if the seats are in good shape, just out of reach. The spindles on these have an outer nut which is adjusted up and down, allowing the spindle body to contact the seat. They have a lot more adjustability than the older style spindles in regards to the depth at which they make contact with the seat. They'll still only adjust 10mm but this might be enough to solve the issue.

You install them by removing the outer nut/cover flange threaded section and then screwing the tap body down until the seal meets the tap seat. The outer nut is then screwed onto the tap body. Hopefully, once you have screwed the tap body in, you'll still have enough thread exposed to screw the outer nut onto it.

Thanks Mitchell they were the push in Kinetic sleeves,the original seat I think were reamed too far with the smallest tool as there are 2 sizes and now the seal becomes stuck in the recess but does not seal properly and there seems to be a break in the seat creating a channel for water to leak,I will try your suggested seal kit but can replace the bottom body if I have some direction with what to replace with,Great response,Krusty.

A crack in the seat sounds like a bit of an issue, and I'm not sure whether a replacement tap seat would fix that @Krusty. I believe the water will try to migrate around the seal and through the crack.

Please let us know how you go and if you decide to go down the path of replacing the lower tap body.

Cheers Mitchell any links to suitable tap ware would be greatly appreciated I am having a hard time finding it on the shelf,a little overwhelming,Krusty.

Hello @Krusty 

As mentioned by @MitchellMc this kit should be sufficient to fix the existing damage to the seats by creating a new thread for the new seats to travel on.

Hi @Krusty,

The copper piece that the spindle screws into is called a breech. It is likely to be similar to a Brassheads WELS 3 Star Forward Bowl Sink Set With 165mm Spout for a basin.

Cheers Mitchell I’ve been looking and asking for replacement taps this clears up the confusion for me and the Bunnings worker I will take measurements to be sure and head straight down for this purchase, thanks a lot Krusty.
