Dan installed a flexible gas line for my gas range as promised. He offered to return, at no cost, if the line needed to be moved after the range arrived. After the initial installation, the range position required adjustment and Dan came as promised (on a Saturday) to move the gas line. As it turned out, the positioning adjustment did not necesitate repositioning of the gas line. Even though the adjustments were not within the purview of a plumber, Dan was very helpful in achieving an ideal position. The gas line has been working well. Also, Dan responds quickly when contacted.
