The taps in the kitchen were replaced a few years ago for ones with
discs in. Now I thought one of the pros of using disc taps was that
there was no washer to perish so the tap would never drip.
Unfortunately the Hot tap (so not subjected to mains pressure) drips,
is this a D-I-Y job to repair (does have an isolating valve in the water
supply) or should I ask the landlord to get a plumber in? Rented
property so not wanting to replace the tap my self.
