New Tap Seat or O Ring

A constantly dripping tap isnt always fixed just with a new washer, sometimes the valve seat will have some damage. The valve seat concerned is the surface that the washer closes on as the tap is turned off. The water pressure under this washer tries to push itself in between the seat and washer, so that over time the water will wear away the brass seat. Small channels form in the seat and let the water pass between the washer and seat and this is what causes the tap to drip. Hard water areas are more prone to this. Enfield Boiler Repairs use skilled tradesmen. If a tap still drips after you have replaced the washer, the seat is probably worn, still allowing the water to leak past the washer. The easiest way to cure this is to cover the old seat with a nylon liner that is sold with a matching jumper and washer. An Enfield Boiler Repair plumber has the experience to do this job. Once you have the piece, drop the liner over the old seat, and replace the jumper and assemble the tap. Shut the tap to force the liner into position. You could use a tap-grinding tool to make a new smooth surface on the seat. The tool uses serrated cutters to grind out any imperfections that might be allowing the water to pass. Remove the headgear and insert the grinder and screw the threaded bush to the tap to locate the tool securely. Push and twist the grinder clockwise. The resurfacing is finished when the whole seat looks shiny and new. With a mixer tap each valve is usually fitted with a washer, as with conventional taps, but in most mixers the gland packing has been replaced with a rubber O-ring. The base of the mixers swivel spout is also sealed with a washer or O-ring. If water leaks from that, it needs replacing. Firstly, remove the mixer spout, and the retaining screw may be accessible from the front, if it is at the back, you may have to use a cranked screwdriver to remove it. Lift out the swivelling spout, then, use a small screwdriver to flip out the O-ring from its groove. Take care not to scratch the metal. Make sure you always lubricate a new ring with silicon grease, then, carefully slide it into place before refitting the spout and replacing the retaining screw.
