Underground Waterline Replacement

Underground Waterline Replacement
  • Underground Waterline Replacement
    $350
    up to $450 per linear foot
Underground waterlines are often subjected to pressure from the soil above and the movement of water within. While the pipes are built to be resilient and durable, they can eventually develop problems and need to be replaced. These pipes are liable to break, collapse, and even burst, especially if they are very old or made from low-quality materials.

Whether it’s changing old pipes or upgrading to modern materials, we take care of every step of the process with skill and attention to detail so your water system functions as it should.

Signs That You Require a Waterline Replacement

Considering your home’s waterline could be located underground, it’s easy to see why it might be out of sight and out of mind. The good news is that even if you can’t see it, there are some telltale signs that your underground water line needs a plumber’s attention. Be on the lookout for issues like the ones detailed below:

  • No Water Supply – You know you have a problem on your hands if you have no water supply but your neighbors aren’t experiencing the same issue. Your water line underground could be damaged and require replacement. The problem could stem from a structural collapse or severe clogs restricting water flow.
  • Minimal Water Pressure – Low water pressure is a telltale sign that the health of your home’s waterline is in question — especially if your neighbors aren’t experiencing the same problem.
  • Soggy Ground and Water Damage – If the ground above the waterline is excessively wet or flooded, water line repair or water line replacement may be required. What starts off as a small leak can become a big one, releasing increasingly larger amounts of water, if the problem isn’t discovered and fixed quickly.

Do It Yourself or Professional for Waterline Replacement?

Unless you know plumbing systems like the back of your hand and have successfully done several installations and replacements, leave plumbing work to plumbing professionals. Water line plumbing isn’t typically a DIY-type task. It’s a complicated process requiring specialized training, processes, equipment, and tools. A plumber must first figure out where the problem is, excavate to expose and remove the damaged section of the pipe, and do the repair or replacement. A licensed professional can also use a trenchless method to avoid the sort of excavation that destroys your lawn.

The Cost of Underground Waterline Replacement

  • Are you wondering about the water line replacement cost? A plumber will utilize a clean out that’s already in place or dig a small hole to access the drain pipe for relining. Expect to pay around $350 to $370 for every foot of a 4-inch pipe.
  • Pipe bursting is more expensive. It’s a more complex process requiring a minimum of two holes to be dug for complete access to replace the pipe. Expect to pay around $400 to $450 for every foot of a 4-inch pipe burst.
  • We can fix 3-inch, 4-inch, and 6-inch old pipes through pipe bursting or relining. For 8-inch pipes, we can perform relining but you have to ask for it specifically.

FAQs on Water Line Repair and Pipe Replacement in Toronto and the GTA

Who is responsible for the water pipe into the residence?

In Canada, the homeowner and the city share responsibility for the water pipe into the residence.

  • Communication Pipe (from the street to your property boundary): The city bears responsibility for the communication pipe that goes from the water main on the street to the boundary of your property. If you see a leak on the sidewalk or road, the city should attend to the situation and ensure it gets fixed.
  • Supply Pipe (from your property boundary into your residence): As a homeowner, you must take responsibility for the supply pipe that brings water from the boundary of your property into your residence. If you see leaks in this section, the responsibility of hiring a plumber to fix it falls on your shoulders. The city may assist in some scenarios through private leak investigation programs.
How often should I replace water lines?

It depends on the pipe material. Copper pipes last 70 to 100 years but may corrode over time. PVC pipes, meanwhile, can last 50 to 70 years, galvanized steel pipes can last 20 to 50 years but are susceptible to rust and corrosion, and polybutylene pipes often last only 10 to 15 years before succumbing to brittleness.

How long does it take to replace a water line?

On average, it can take between four and eight hours to perform a main water line repair. The cost will depend on factors that include, but aren’t limited to, the underground water line installation cost per foot, the experience and expertise of the plumber, and the process used.

Shut-off Valves Installation

I recently hired Cheap Plumber to install new shut-off valves for my kitchen and bathroom, and the experience was excellent from start to finish. Booking the appointment was easy, and the plumber arrived right on schedule. He explained what needed to be done, replaced the outdated valves efficiently, and even checked for any potential issues while he was there.

The work was done neatly with no mess left behind, and the pricing was exactly what they quoted—no surprises. I now feel much more confident knowing I can shut off water locally in case of an emergency. Highly recommend Cheap Plumber for this kind of work—fast, honest, and professional.

Old Cast Iron Pipes Descaling

We recently had Cheap Plumber come in for cast iron pipe descaling, and the difference has been incredible. Our drains were slow and noisy, and we were starting to get worried about a full blockage or worse. The team showed up right on time, walked us through the process, and got to work with minimal disruption.

They used special equipment to clear out years of buildup inside our old pipes—no digging or tearing things apart. By the time they finished, everything was flowing smoothly again. It was fast, clean, and surprisingly affordable. I highly recommend this service if you have an older home like ours. These guys really know what they’re doing!

Pipe In Powder Room and My Experience With CP

A few days ago the sink in the powder room started to leak. The pipe was corroded where the trap is located. I called Max and he sent Andres who replaced the pipe and left the powder room in perfect order. He was fast and efficient. I’ve used Max and his team for 10 years for major jobs replacing lead water lines in the front yard and installing a much-needed backwater valve under my house to prevent flooding during heavy rains. During a winter freeze, my pipes froze inside the wall and burst at midnight. Max’s team was here by breakfast and moved the vulnerable pipes from the exterior wall to inside the ceiling. Hardworking, decent, efficient crew.

Replaced Horizontal Sewer Line In Basement In 100 Year Old House

I was renovating the basement of my 100-year-old house to replace the very old crumbling clay horizontal sewer line out to the street. I had several unsatisfactory quotes from other plumbers. I then contacted Cheap Plumber. Max was very reasonable and very efficient and timely. They also suggested a backwash valve that will prevent the sewer from ever backing up into the house. I agreed and they provided an excellent price and did a superb job. This week, I decided to install the Moen Flo valve (sold by Home Depot Canada and Amazon.ca) that shuts off all water to the house – IF ever there is a leak anywhere in the house in the toilet or water tank etc. I immediately contacted Max – who provided an excellent price and was able to install it shortly after the valve arrived. I was very pleased as no leaks and they cleaned up afterwards. I will use Max and Cheap Plumber for any future plumbing jobs. I strongly recommend this company.

Back Water Valve Installation

Max and his team installed a back water valve in my house, replaced some of the water lines, installed new water meter for me. Everything was done quickly, professionally, perfect clean up, filled out and submitted the forms for the rebate from the city. When I noticed a tiny leak after the job completion, a technician was sent over within minutes and everything was fixed very quickly. The services were reasonably priced, and I would definitely recommend this company to anyone with plumbing needs. Thank you!

Drain Work

I had to get the water service line replaced because of the new smart water meter requirement. Got quotes on a monday. Went with Max and although I was a little concerned about the lack of reviews on Homestars, I went with my gut and my gut was right. The work was done by wednesday (in by 8:30 out by 3:30). Max and his guys were punctual, careful about maintaining site cleanliness and very respectful. His price was the best of three quotes and he is honest and straightforward in his communication. His follow up once the job was complete was great. I highly recommend Cheap Plumber for any plumbing issue you may have and I am happy with my new water pressure!

Cracked Soil Stack

Our 98 year old cast iron soil pipe needed replacing. Replacing it was tricky as we had a newly renovated kitchen and basement bathroom and the stack was embedded between the outside brick wall and the new tiles and cabinets. Max and his crew did an amazing job of replacing the stack with only minimal damage to the basement bathroom and none to the kitchen. He then had a crew come in to restore the wall, tiles, etc in the basement. The team is hardworking, trustworthy, and professional. This is the second job they have done for us and both times we were more than satisfied. Ps. They are also just really nice people. Worth every penny.

Andrew did a great job fixing our drain. He was punctual, polite, knowledgeable and very patient with my questions. He quickly identified the problem (tree roots in drain pipe) and worked hard on snaking the tough roots until he was satisfied everything was clear. We were so lucky to have his help. Thanks Max and Andrew!
