Groundworks knows how to solve basement, and crawl space problems, the first time. Proudly serving Montana and Wyoming.

"WOW! Groundworks is a great, reliable company! We had the dream team, Ryan, Alejando (Alex) and Jose, working on our home. Ryan kept us informed on what was going on the during the whole project. Ryan and Alex were so reassuring of all our fears and concerns, we knew we were in good hands. Alex and Jose were so polite and talk about hard working!! All three of them went above and beyond, exceeding our expectations, saving some landscaping we didn't expect to be saved. They took great care with our landscaping and yard and did not cause any unexpected damage to any of it! They did a great job with the clean-up at the end of the job as well. These three men worked great together as a team. We were happy to see them everyday and a little sad when we said good bye."

Additional DBAs - Frisby Inc, Roto Rooter Plumbers & City Service, Plumbing & Heating, Billings Roto-Rooter Frisby Inc.

"The home with the cracked sewer line was built in 1935 and the sewer line and clean out were made of cast iron. For some reason the cast iron pipe cracked about one foot above the basement floor, right where the sewer exits the house. The concrete floor in the basement had to be jackhammered out to replace the cracked sewer line. Bill, the plumber assigned the task, did an outstanding job in, what I felt, was a minimal amount of time. To say I was impressed with the skill of this plumber, would be an understatement. Great job at a reasonable price. A floor drain was also cleaned, two days earlier, by a technician named Roland, who also did a great job."

Drain Pipe Installation questions, answered by experts

In North America, pipe measurements are listed as the nominal pipe size (NPS). This measurement refers to the outside diameter. As an example, a 1/2-inch copper pipe has an outside diameter of 5/8 of an inch. If a hardware store lists a pipe as having a 2 NPS, it means that all the pipes with this measurement have a 2 ⅜-inch outside diameter, regardless of wall thickness and inside diameter.

To unclog the drain pipe, remove the machine's drain hose from the pipe or sink drain, being careful to contain any water in it. Next, use a plunger for sink drains or a plumbing snake for a wall drain. Test the repair by pouring a small amount of water into the pipe before trying it with a laundry load.

The amount of clean water your cistern can supply depends on its size and the local rainfall patterns. Cisterns range from a few hundred to several thousand gallons in capacity. 

To estimate the potential supply, consider the average annual rainfall in your area and the catchment area of your roof. For instance, a 1,000-square-foot roof can collect around 600 gallons of water from just one inch of rainfall. 

Multiply this by the average annual rainfall to get a rough idea. However, factors like evaporation and system efficiency will also play a role.

If you have the necessary skills, you can attempt DIY plumbing installation for simple systems, but professional installation is recommended for complex systems to comply with codes and ensure safety.

Annual inspection prevents leaks, blockages, pressure issues, or other problems from developing.
