"When our septic pump stopped working I called Superior Septic. Angel came out and figured out the complicated problem that could have eluded someone with less experience, and skill. I am impressed with how fast he fixed our pump. I highly recommend him and his company."

"The pressure pump on our well system failed on July 4th. We have a irrigation system for our extensive home vegetable garden and dreaded the prospect of hand watering half an acre of crops. Romero (The owner of Quality Pump Service) returned our phone call over the holiday weekend within a hour. They are a family run business. He was willing to come to our home and install a temporary pump on Sunday as a new pump would not be available for two days (Remember it is the July 4th Holiday weekend). In short, we were completely repaired in two days with a new pump and new pressure tank. We checked on-line retailers to see if Romero had overcharged us for the new components. He was within 5% of the average retail price which would have been our cost if we had fixed the system ourselves. His team was fast, pleasant and professional and given the holiday emergency response very fairly priced. We feel we can highly recommend Quality Pump Services."

"Micah is a trustworthy, very knowledgeable tradesmen. He genuinely loves his work, and he does exceptional work. Ià ¢à  à  m a licensed contractor and I would only call Micah for the big complicated jobs and also the technical jobs that just need to fix instead of a complete replacement which would normally cost thousands. He has done under ground work, new construction work, remodels, big jobs and small jobs that I hired him for. 5 stars all the way."
