"Very polite salesman who went over the work choices we could do and gaves us several options to choose from and price quotes on each option. The workers were very friendly and hard working. They showed us what they were going to do as they went along in the process. That part was very interesting to see what they were going to do and we could ask questions as we went along then. We did the who outside drainage work and foundation waterproofed. Put in a new back up sump pump and did a whole perimeter drainage system and braced two walls. We were very impressed with the work and all the workers. I would recommend them to anyone."

"Central Wisconsin Excavating (CWE) did a fantastic job on our project. They built a solid, well-prepared foundation for our 80,000-bushel grain bin and graded our driveways perfectly to ensure water drains away from our buildings. Their attention to detail, quality of work, and professionalism really stood out. The site was left clean and properly finished, and everything was done right the first time. We’re extremely happy with the results and would highly recommend CWE to anyone needing excavation or site work done right."

Drain Pipe Installation FAQs, answered by experts

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.

Yes, you can pour water down the toilet to help it flush. For each flush, you’ll need 1 to 2 gallons of water for newer toilets or 3 to 5 gallons of water for older toilets. Rather than dumping the entire bucket in all at once, pour the water in slowly for the best results. If you’re pouring water down the toilet to help it flush after a clog, only use 1 gallon of hot water.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

With a one-way cleanout, you can access your sewer line from one direction. Depending on the way it curves, a plumber can either access the side of the pipe that goes into your home or the side that goes to your yard. On the other hand, two-way cleanouts allow pros to access both sides of the sewer line, thanks to their dual-pipe design (they’re usually U-shaped).

Air gaps get clogged by a few different means. Over time, food and grime can collect in the air gap, leading to a blockage. Mineral deposits from hard water are a common problem. Mineral buildup creates a film in the air gap and tubing, which can cause flow issues, as well as attract debris. Homeowners with hard water may want to remove mineral deposits regularly to keep the air gap clean and clear.
