"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."

"I had a leak in a pipe in the radiant heating pipes in the slab under my house. James was able to isolate the leak and re plumb my system without cutting a hole in the slab. He and his crew did some great creative plumbing that took care of the leak and separated the unused radiant system from my household plumbing and they even installed a new tankless heater in a single days work.. I recommend James and Bowen Plumbing without reservation. They are the Best!"

"Absolutely GREAT! I had places to go in December and ordinary bathing and laundry had become extremely time consuming and the problem was worsening. He came out on an already busy day for him and had the whole system (more complicated than some) removed, and the plumbing working again very well in a bit over an hour. Wonderful! I can't add enough superlatives! Left a clean area, besides!"
