I have had several people at home look at our set up to see if we could install a water softener and everyone said that it would not be possible without digging up a very expensive quarry kitchen floor. Without the persistance of your excellent plumber, we would not have succeeded on this occasion. First he located the stopcock in one of the cupboards, we had no idea where it was, and managed to saw a hole to enable him to identify which way the pipes ran. In our opinion, he went way beyond the call of duty and was first rate in every respect. I cannot compliment this young man enough for his courteous manner and his excellent plumbing skills.
