Notice an Increase in Your Water Bill?
Over time, your water line wears down and can become damaged. When this happens, you may have a pinhole leak in the line that will raise your water bill. In some cases, the leak is large enough that you can see it on the surface of the ground. Either way, it gets expensive to keep wasting that much water!
If you notice an unusual rise in your water bill, contact a plumbing service professional as soon as possible. Our team of experts can run the necessary tests on your home to verify that it is the main line that is leaking and not some other fixture in the home that is causing the problem.
Signs Your Water Main Is Leaking
- A stream of water through the foundation wall - although this is not necessarily a sure sign, as it could be a leak from a house nearby, you should call a plumber right away if you notice this sign.
- Rumbling or hissing sound when your water is shut off in your house - this could indicate that water is leaving the pipe somewhere between the house, the city water main, and the street.
- Loss in water pressure - if you notice your water pressure has decreased, your pipe may have been damaged.
Call a licensed, trained professional if you suspect a leak in your water main. Our well-trained technicians have years of experience and a trained eye to spot the source of a leak.

Frequently Asked Questions
Q: How can I determine if my main water line is malfunctioning?
If you notice a sudden decrease in water pressure throughout your home, unexplained increases in water bills without a change in usage, water stains or damp spots in the yard, or persistent wet areas, it could signify a malfunction in the main water line. Additionally, audible sounds of running water when no fixtures are in use or unexplained puddles in the yard, driveway, or basement might indicate a water line issue.
Q: How frequently should inspections be conducted on the main water line?
It's recommended to conduct inspections of the main water line periodically, approximately every 1 to 2 years, especially for older properties or in areas prone to issues like tree root intrusion, shifting soil, or extreme temperature fluctuations. However, if you notice any signs of leaks, reduced water pressure, or other irregularities, it's essential to schedule an inspection promptly.
Q: What might be the repercussions of neglecting problems with the main water line?
Over time, undetected leaks or damages may worsen, causing extensive water damage to your property's foundation, walls, or landscaping. Persistent leaks can result in increased water bills and potential mold or mildew growth, posing health risks. A neglected main water line might eventually lead to complete failure, resulting in a sudden loss of water supply and costly emergency repairs.
Q: What steps can be taken to prevent issues with the main water line?
Conduct regular inspections by professional plumbers to detect any potential problems early. Be mindful of landscaping activities, especially when planting trees, to avoid invasive roots damaging the water line. Proper winter preparation with insulation and drainage prevents freezing. Avoid placing heavy objects over areas where the main water line is installed to prevent damage. Monitoring water usage and bills helps detect any sudden increases that might indicate leaks.
Q: What is the normal water pressure for a home?
The normal water pressure for a home is between 40-80 psi. Water pressure in your home is very important and should be tested. It is important to keep your water pressure within the recommended range to make sure your plumbing system can run efficiently and not cause any damage.

Warning signs
Signs Your Main Water Line Is Failing
Most main water line failures build for weeks or months before the blowout. Catching it early turns a $12,000 emergency into a scheduled $5,000 replacement.
Wet, sunken, or unusually green patch in the yard
Water bill up 30% or more with no change in usage
Low pressure across every faucet and shower in the house
Rust, sediment, or cloudy water out of every tap
Audible hiss, vibration, or gurgle from the main shutoff valve
Gravel driveway or sidewalk visibly sinking in a line from meter to house
No water in the house but fine at the meter
Basement wall dampness along the supply line entry point
Sound of running water inside the house with every fixture off
Active break
Water gushing in the yard? Shut it off and call.

The Process
How a Main Water Line Replacement Goes
On-site diagnostic walk
Tech walks the property, locates the break (or suspect area), checks the meter, runs pressure tests inside. You get a written diagnosis and a scoped quote before anything gets dug.
Blue Stakes + permit
We file the Blue Stakes Utah 811 locate (2 business day lead time), pull the city permit, and coordinate with the water department on meter scheduling.
Excavation + new line
Mini-excavator digs the trench between meter and house, we pull the old pipe, lay the new PEX-A, copper, or HDPE with proper bedding sand, and tie into both ends.
Pressure test + inspection
Full-system pressure test at 150 PSI for at least an hour. City inspector signs off before we backfill — not optional.
Backfill + surface restoration
Proper compaction layer by layer to prevent settling. Sod or gravel topsoil restored to pre-dig contour. Concrete or asphalt patch scheduled if the trench crossed a driveway.

Open Trench vs. Trenchless vs. Spot Repair
Three ways to handle a main water line failure. Choice depends on line condition, length, what's above, and budget.
| Feature | Open Trench | Trenchless Bursting | Spot Repair |
|---|---|---|---|
| Best for | Short runs, soft yard, budget | Long runs, landscape, driveways | Localized leak, young pipe |
| Cost range | $3,200 – $8,500 | $6,500 – $14,500 | $685 – $1,850 |
| How long it lasts | 50+ years on PEX/HDPE | 50+ years, minimal disruption | 5-10 years (not a real fix) |
| Yard damage | Full trench, restoration needed | 2 small entry pits | 1 small excavation |
| Time on-site | 1-2 days | Same day in most cases | Half day |
| When it's the wrong choice | Crossing a concrete driveway | Short runs, unfriendly soil | Pipe is old/failing throughout |
