Emergency assistance with a leak in the basement

I went to my basement to put some clothes in the washing machine and found water on the floor with a spray of water coming from a pipe. I called Black Diamond and they understood the emergency and shortly their plumber arrived. Michael H was polite, efficient, and a born educator. He replaced the spouting pipe with a copper one (I was delighted with that) and answered questions I had about the temperature of the new water heater I had had installed in September (not by Black Diamond). He reset the temperature on the water heater (it was scalding hot the moment I turned on the tap). I told him about a different issue I was having and he explained the problem, but said he could not correct it at this time since he had another call. I told him I would call the Diamond again to have that handled. Michael was a wonderful representative for Black Diamond and I would hope to have him respond when I call next week. People had told me for years that Black Diamond was VERY expensive so I had avoided calling them. I want to go on record saying that the company is more reasonable than several of the other companies with which I have done business in the past Black Diamond is not only more reasonable but they finish the job correctly.(unlike one company whose representative reversed the hot and cold taps in the shower).Thanks Michael H and Black Diamond! I look forward to making an appointment next week.

Fixed a major plumbing disaster shortly after move-in

When I experienced a major plumbing disaster shortly after moving into my new house, Black Diamond was able to get a technician out to deal with my issue even though it was a Sunday. While that initial visit did not fix my problem, the followup visit did. The piping from my main sewer line was misaligned, likely at the construction of the house decades prior, and was going to be a serious problem leading to ongoing clogs if not addressed. It required jackhammering the concrete around the relevant piping in my basement but the end result was new pipe that ensured a functioning toilet and shower which could not clog in the same way ever again. The nature of the service was expensive, but all three technicians over two visits were highly skilled and completely professional, even giving me a discount for the first visit by changing for the attempt, rather than the considerable time invested.
