Steel cutter doesn’t hold an edge for long at all. Basically blunt after one tap seat. Went to do the second and it’s taking off about as much as sandpaper would. Waste of money.

I had previously attempted to smooth the seat of this tap using a re-seater with a tapered thread claimed to be suitable for 1/2" and 3/4" taps. The tap continued to require much force to turn off. When taken apart it was obvious that the seat was not at right angles to the tap spindle. I blamed this on the re-seater I had used and so bought the Fix-a-tap re-seater which screws into the thread in the tap body. I found it difficult to tighten the new re-seater in the tap body because most of the screw-in portion disappeared into the hole in the wall leaving nothing but another thread to grip it with. I eventually tightened the re-seater in the tap body and carefully cut the seat smooth and flat over its full surface.

I eventually tightened the re-seater in the tap body and carefully cut the seat smooth and flat over its full surface. On re-assembling the tap with a new valve and washer I found the tap still difficult to turn off without dripping. The tap was obviously manufactured with the body thread not properly aligned with the seat. This is not the fault of the Fix-a-tap re-seater but of the tap manufacturer but the problem of tightening the threaded guide section of the re-seater in deeply recessed tap bodies still remains. Other re-seaters have longer guides and can be tightened with a spanner.

Refinish the tap seat on both cold and hot water taps with no problem. The hot water tap seat has big gouge on it and the tool accomplished the job excellently.
