Recent Review: It went FLAWLESSLY! Keith and his assistant work in hand-in-hand tandem as if each knows what the other is thinking. Removing a large water tank and replacing it with a new one seemed very daunting to me but they made it look effortless! They had no problem with my taking pictures of the operation( because I just couldn't believe how flawlessly they performed). While they worked, I asked (and they graciously answered) a "bizillion" questions about the wiring, the integrity of adjoining pipes; the effect if any on the foot valve, etc. When you're dealing with someone who KNOWS what they're doing, it's the most secure feeling in the world! When Keith and his assistant were finished and we said our farewells, I said a "Thank you God" for their having been here!
