It seems that the NCA installer was not used to resolving difficulties or dealing with anything except new construction. Yes, I live in a hundred year old house, and I knew it would be nasty under a dishwasher which had been in place for 15 years. When asked to move the dishwasher further, so I could get in to vacuum and clean this installer refused !
He was incredibly rude, blaming me for having a ‘******' attitude’ (his words) because I did not take everything he said at face value. I chose to question his ‘authority’, when he indicated that my plumbing set up was ‘illegal’, which it is NOT. Yes, I was upset, and for good reason.
I asked him to take away the old and bring in the new, without installing....this man flatly refused !
Because this installer decided not to complete the job, he thought it was just fine to leave the old dishwasher in the middle of the floor, and to drive off with the new one !
After I called the retailer, and the new dishwasher was delivered back to my deck, and the old one removed (which I had taken out of the house myself)...the young fellow, who I guess was the helper of the two, was so conciliatory. He offered to unpack the new one and move it into the house for me. He was as apologetic as can be. This let me know I was not out of line.
I am still shocked at how I was treated. This was a horrible experience.
As an aside, I called my own plumber, who has a stellar reputation and been in the business 35 years. He added a valve, made a small correction to the drain hose, and the dishwasher was installed within 45 minutes. All using the original service and drain lines, with slight modifications. And all legal, I might add.
