"I brought two sets of these taps. The first set went on with no problem, but the second proved problematic as I couldn’t tighten the taps because the rubber washer would disappear up the tap hole on the sink. I resolved the problem by adding steel washers. The difference between the two sinks? Well the sinks were the same, but the first connected directly to the water pipes, whilst the second used flexible hoses. I also found the basin wrench too big and I had to use a 24mm spanner, but this was a minor issue and once fitted, they looked smart and certainly have a quality that suggest they will last."
