Fredy was great - he clearly knows his way around plumbing and HW heaters. He was able to quickly diagnose the problems I was having with my newly installed HW unit - turned out to be the condo building's fault (building water pressure much too high). He cleaned everything up and set the unit so it was safe and not going to cause any problems unit the water pressure problem is fixed, which is great peace of mind for me as the last thing I need is water leakage 5-floors up in a condo building... :-) Also - like his colleagues who did the install, Fredy was attentive to taking care to not damage my new hardwood floors - which was very much appreciated!
