highway rubbery!!! never call this company. you will be sorry. after they fixed it, just two hours later it happen again. no warrant what so ever they took a money, that's it. after 4times of calling the office what I heard is : you have to change whole hot water tank, I will give you special price 1550.00!!! of course there is no warranty at all!!! I call other plumber, he checked and say there is nothing wrong, just need put fire on it. he turn on the fire . I think plumber from this company just change the switch for nothing and ripped me off 207 dollar. the plumber.'s name is Mike Massullo. Avoid this man!!! never call this company!!!! it's like your car battery is gone, and the mechanic said : you have to buy a new car!!!"
