"I originally called another septic company to do my five year pump out of the septic tank. This was our first time having this done because we didn't own the home the last time the septic was pumped. The other company was so incompetent and couldn't find the hole to pump out the septic tank after looking for about 15 minutes. They told me they would need to git a backhoe to come out a dig. I assured him that I remember the selling real estate agent telling me that the previous company that did the work didn't have to go through all that hassle. I was able to find out that the previous company that did the work was Great Falls Septic Service so I gave them a call. The technician was able to find the septic tank riser, which was buried about 10 inches down in about 2 minutes. I am extremely pleased with the service that I received. The technician was extremely efficient, technical, professional, and courteous. I would highly recommend Great Falls Septic Service."

"RightNow Plumbing reliably provides competent, scrupulous, trustworthy service. Recently I engaged Andy to service our well-water acid neutralizer tank, because I questioned the reliability of service by another company 13 months earlier. Andy tested our water and found that its pH value was 6.97, which was consistent with previous readings over the past six months when he did other work for us. Because our well-water pH is essentially neutral, Andy explained the acid neutralizer tank is not necessary. He offered two options: 1) remove the tank (thus leaving us with only the water softener tank) or 2) empty it, which option I selected. He also reduced the cost of the service call. Andy’s approach starkly contrasts with the other company that for years took advantage of an unsuspecting customer by charging almost $300 to “service” the tank and unnecessarily adding expensive calcite. For competent, scrupulous, trustworthy service, call RightNow Plumbing. Posted May 14, 2025"

Customers say: Quality work

"Commonwealth Plumbing is a small local operation. The plumber came quickly to assess my farm well pump problem and was ready to tackle the job. He received a call from a customer who had no water in the house with children. The plumber asked if he could take care of that job first as a genuine concern. My well pump is just for irrigation which is not critical compared to a family without water. The plumber headed off , took care of the family and returned first thing the next morning and repaired my system. Excellent work, reasonable price, as well as compassionate."
