Was doing a repair on a pool heater and whoever had initially installed the pool equipment and heater had completely installed the natural gas lines incorrectly. This posed a problem for me because I could not fully get the heater elements out without the gas line being disconnected. Called MC plumbing to ask if they could tackle this small, but for me big issue. They told me it wasn't a problem and literally would have had someone out the same day(called at 3:30PM), but I had other jobs to attend too. Needless to say one of their technicians was there first thing in the morning, got everything re-plumbed the correct way allowing me to do my job and fix the heater, in return all parties were happy and my customer was very pleased. Will definitely be calling them for all plumbing needs and issues from now on!
