The installer came and after looking at the dishwasher and existing lines, he said he could install. "I've installed 100's of d/ws". After my signing the paperwork to proceed with the work, he got to it, bent the copper tubing for the water inlet (that's ok, the water will come through"), started using the back of his wrench to put on the compression nut. He went outside to make a phone call - turns out it was to his office - apparently it was my fault that I didn't tell the call centre I had copper tubing! I should have read the reviews on the Company before calling. Outrageous they are still in business.
