Replace Failing Lines That Limit Water Flow
DNI Heating and Air installs new water lines for homes and businesses in Boulder, Colorado when old or damaged lines affect water pressure and quality.
When water pressure drops throughout your home or business in Boulder, or when you notice discolored water and frequent leaks, the problem often traces back to aging or damaged water lines that no longer deliver water efficiently. Old galvanized pipes can corrode from the inside, reducing flow and contaminating water, while damaged lines may leak underground and waste water without visible signs until the pressure becomes noticeably weak.
DNI Heating and Air installs new water lines in Boulder for properties experiencing issues with old or damaged lines or dealing with low water pressure that affects daily use. The installation process includes checking local codes, ensuring correct pipe sizing for your needs, and securing all connections to prevent future leaks. New water lines are typically made from copper or modern plastic materials that resist corrosion and provide consistent flow over time.
If your water pressure has declined or you suspect your main water line is leaking or deteriorating in Boulder, reach out to discuss replacement options and schedule an assessment.
New Lines Restore Pressure and Eliminate Underground Leaks
Installing a new water line in Boulder begins with locating the existing line, determining the best route for the replacement, and excavating access points to remove the old pipe and install the new one. The new line is sized according to your property's water demand and connected securely to the municipal supply and your interior plumbing system. All work is performed in compliance with Boulder building codes, and connections are pressure-tested to confirm there are no leaks before the trench is backfilled.
After installation, you will notice improved water pressure at all fixtures, faster fill times for appliances like dishwashers and washing machines, and water that runs clear without rust or sediment. There will be no unexplained wet spots in your yard or driveway, and your water bill should stabilize if it had been climbing due to hidden leaks.
The installation process involves digging a trench from the street connection to your home or building, which means some disruption to landscaping or paving. The trench is kept as narrow as possible, and the surface is restored after the line is installed and tested. In some cases, trenchless methods may be used to minimize excavation, depending on site conditions and the layout of existing utilities.

You Likely Have Concerns About Installation and Timing
Replacing a main water line is a significant project, and homeowners often want to know what the process involves, how long it will take, and what kind of disruption to expect. These details depend on the length of the line, soil conditions, and access to the existing connection.
What are signs that I need a new water line?
Common signs include low water pressure throughout your property, discolored or rust-tinged water, frequent leaks, wet spots in your yard, or an unexplained increase in your water bill. These symptoms often indicate corrosion or damage in the main line.
How long does it take to install a new water line?
Most installations are completed within one to three days, depending on the length of the line, soil conditions, and whether trenching or trenchless methods are used. We coordinate the work to minimize the time your water service is interrupted.
What type of pipe is used for a new water line?
We typically install copper or high-grade plastic pipe such as PEX or HDPE, depending on local code requirements and site conditions. Both materials are durable, resist corrosion, and provide reliable water flow for decades.
Will my yard be damaged during installation?
A trench will need to be dug to access the old line and install the new one, which may disturb landscaping or paving. We keep the trench as narrow as possible and restore the surface after the work is complete. In some cases, trenchless installation can reduce surface disruption in Boulder.
Do you handle permits and inspections for new water line installations?
Yes, we obtain the necessary permits and schedule inspections as required by Boulder regulations. All work is performed to code, and connections are tested and inspected before the project is considered complete.
A new water line resolves ongoing pressure issues, prevents further water loss from leaks, and provides reliable service for the long term. If your water pressure has dropped or you are dealing with frequent leaks and discolored water in Boulder, contact DNI Heating and Air to schedule an evaluation and discuss installation options.
