Arash turned upon time with a very pleasant smile and a positive "I can do" approach. "First things first" I said and over a cup of coffee and a biscuit I explained in layman's terms the problem we were experiencing with the 2 showers. Does not sound like air in the pipe to me was Arash response. So I left him pretty much to it and literally within 10 minutes I heard the sound of running water. Is that the shower I shouted up into the loft. It is was the reply. Well, well, 3 visits from British Gas to no avail the last being just 2 weeks or so ago and after a good hour the "engineer" reappeared from the loft saying the pipework is all wrong (after 20 years with no problem, really?) and that he would let me have a quote for the correct fittings - I am still waiting !!!
Well done Arash and many thanks for your very professional, polite and positive approach to my shower problem. Without a doubt I will use him again. Thoroughly recommend Arash.
