I had Leachmans installed plumbing for a new washer in dryer in my home. I have to say I was not really impressed with them. First I wanted to have the plumbing behind the washer and dryer (not on the side) but when I got home after work they told be they could not get it through the back so they placed it on the side (they really should have told me about that before proceeding). I was a bit upset but trusted their expertise.
I later found, when my electrician came to finish the job to install the electrical components of the job and the vent for the dryer, that not only they could have gone through the back like I wanted (it would have been more difficult, but much more convenient for me once installed), but that by moving the plumbing to the side they had actually damaged some of my wiring (as pictured, you can see the empty drilled holes and the damaged wire). They ought to have known there was a wire there as it was clarly visible (also pictured) but they still damaged it and failed to tell me about it.
It is clear they knew they hit something and they probably knew exactly what it was. Nevertheless, I brought the issue to their attention and demanded compensation for material and time for my electrician on two occasions, but they did not even acknowledged my complaint. My electrician only found out because he was doing other work in the house. If the issue had gone unnoticed, it would have left live and exposed aluminum wires in my home, which is a significant fire hazard.
On the bright side, the install works, but it was far from a nice experience.
