"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

"I got a call from Mike right after placing the request. We set up a time to come out and fix the clog in my tub and he was early. Within 45 minutes he had the clogged drain fixed working properly and gave some professional advice on the drain system. I would highly recommend using them for all plumbing needs."

Sewer Cleaning FAQs, answered by experts

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.

Outdoor plumbing issues are no less serious or urgent to fix than interior plumbing problems. These problems may require excavation and lawn repair due to the plumbing often being buried underground. The most common outside plumbing problems include:

  • Clogged landscape drainage: $200–$1,000

  • Clogged sewer lines: $60–$250 per linear foot

  • Corroded or rusted pipes: $1,500–$15,000+

  • Leaking drain lines: $200–$1,000

  • Leaking water mains: $300–$4,000+

  • Septic system failure: $600–$3,000+

  • Tree roots in pipes: $200–$1,000

  • Well pump failure: $350–$1,500

There are several homemade solutions for clearing a clogged sink that don’t involve pouring harsh chemicals down your drain. Start by pouring hot (but not boiling) water down the drain. This can help dissolve and flush away grease and gunk. A splash of dish soap down the drain can also cut through fat and make it easier to clear the drain. For a more stubborn blockage, grab a plunger and give it a few firm pumps to dislodge the clog.

Some of the most common plumbing problems in mobile homes are frozen pipes, leaking pipes, clogged drains, and low pressure. Since the pipes in a mobile home aren’t as insulated as those in a standard build, they’re more susceptible to fluctuating temperatures and damage. 

Thankfully, it’s pretty rare to find a rat in your toilet. It’s more likely in larger cities with big sewer systems that can be feeding grounds for rats, but even then, you still shouldn’t fret. 

“I wouldn’t worry too much about rats coming up through the sewers,” Bradshaw says. “I’d say only one out of a thousand rodent customers we get actually have this problem. And of the 20 or some customers that have had this happen, they’ve all only had just one rat come up this way.”
