Sam has called back after he had missed my call, he advised while still on the phone as to what he thought the problem might have been and how he can fix it, asks me to send him a pic of the faulty tap and quotes me a reasonable rate. It was the weekend. Surely enough it was exactly the same problem as what he mentioned. He then comes down within a short time and replaces the tap. Problem now solved and we did not have to wait having the water main turned off and with no water in our bathrooms and kitchen all evening and overnight until the next day. Sam has provided a prompt, quality service for a very reasonable rate even on the weekend. Very happy and grateful. Strongly recommended.
