What Are the Most Common Plumbing Issues in Thornton?

Nestled under the Rocky Mountains and just minutes north of Downtown Denver, Thornton, Colorado is a picturesque and bustling place to live.  The snow-capped peaks of the Rockies provide the perfect backdrop to a city that prides itself on outdoor activity and environment-friendly development. People flock to the area for job opportunities, retirement, and access to all the amenities the area has to offer.

The housing market in the Denver area is booming, so development in and around Thornton is at an all-time high. As such, Thornton has a diverse mixture of new homes, trendy condos, and historic architecture. Some areas have much newer houses than the national average, so aging plumbing isn’t a concern in many of the newly-developed areas. However, there are still many Thornton neighborhoods with historic homes and original plumbing systems, so there are a variety of problems that can plague homeowners here. They can include:

  • the necessity to upgrade dated plumbing;
  • clogged drains, particularly those caused by mineral deposits from our hard water;
  • leaking fixtures, primarily due to the corrosive nature of our water; and
  • maintenance of lawn sprinkler systems

Colorado’s arid climate makes water conservation a common concern for residents. Landscaping sprinklers and water-efficient fixtures are a prime concern for homeowners in Thornton, so we often get calls to address these issues.

How Does the Water in Thornton Affect Your Plumbing?

Denver is dubbed the “Mile High City” for a reason. Due to its location at more than a mile above sea level, Denver and the surrounding metro area, including Thornton, have particularly clean water. The city of Thornton Water Quality laboratory makes sure that the city’s drinking water meets all state and federal drinking water regulations and publishes an annual water quality report. The water supply starts as snowmelt in the Rockies and makes its way down the South Platte River where it’s collected and stored in gravel lakes prior to treatment. This short trip from the mountains to the faucets of residents gives the water a short amount of time to absorb impurities.

One issue facing Thornton homes is the hardness of the water. While the hardness varies from year to year and levels remain typical of systems in the western United States, elevated levels near 330 mg/L can negatively impact plumbing systems. Due to recent drought-like conditions in the area, levels remain high for the foreseeable future.

Water hardness can cause irritating problems such as white spots on your dishes, but it can also lead to more pressing issues like limescale buildup inside pipes and fixtures.

How Much Does Plumbing Usually Cost in Thornton?

Plumbing in the Denver metro area can be pricey because our plumbers have to be skilled in adapting aging plumbing in historic homes while still maintaining current plumbing and building codes. Our plumbers typically charge a dispatch fee in addition to an hourly rate for plumbing work. In the Thornton area, you can expect to spend between $125 and $900 to have plumbing work done, but that does not include the cost of materials. There are several factors that can add to the cost of your plumbing work.

Specific Parts

If your plumbing job is going to be complex or require the purchase of fixtures, the cost will go up. For instance, replacing a water heater will be more expensive and labor-intensive than replacing a gasket around a leaking washing machine hose because you’ll also need to purchase a new water heater. Likewise, if your older home needs extensive internal pipes replaced, the cost factor of obtaining new pipes is included in the overall cost of your project. 

Type of Service

The more difficult and labor-intensive the work you need to complete is, the more expensive it’s going to be. Also, if you’re hiring out a job that will require lots of permits, it will take longer and cost more than one that doesn’t. The scope of service is critical in determining exactly how much you’ll pay for plumbing work.


Emergency plumbing service will always cost more than regularly scheduled maintenance; that’s just the nature of any service industry. If you can wait out your plumbing problem and call during regular business hours, you will spend less than calling late at night, on the weekend, or a holiday.

Prices also go up during periods of high demand. For instance, during Thornton’s long, dry summers, everyone will be calling to have their sprinklers serviced. If you can call during the spring before the weather heats up, you’ll be saving money. Hail storms or quick snowmelt can cause flooded yards and backed-up sewer drains, leading to a similar jump in demand. If you are proactive in your plumbing maintenance and don’t need to call during an emergency, you’ll also pay less overall for the same work.

Can Better Plumbing Save You Money in Thornton?

Efficient, well-maintained plumbing will save you money no matter where you live. For residents of Colorado, this is particularly true as cities and counties prepare for potential drought conditions each summer. Conserving water isn’t just good for the environment of Colorado, it can also save homeowners a bunch of money on their water bills. One of the ways that are accomplished in Thornton is updating home plumbing systems. The EPA gives several great tips on conserving water on their website, but a few of the best ideas are to install new fixtures and keep up on regular maintenance.

Installation of New Fixtures

Installing new fixtures can have the biggest impact on both your conservation efforts and your water bill. Just installing a water-efficient faucet in your bathroom can save the average family of 4 up to 700 gallons of water each year. The City of Thornton is currently offering incentives for residents who upgrade their toilets to a water-conserving model. Rebates of $75 are offered to those who replace them with certain models.

A new sprinkler system can save more than 100 gallons of water each time it is used. In one season, that can mean over 8,000 gallons of water.

The City of Thornton works together with the Center for ReSource Conservation to provide a free series of tests on your underground lawn irrigation system that can help to figure out how efficient your sprinkler system is. Personalized sprinkler consultations are available from June through August and you can sign up online to schedule one. Consultations help you:

  • Save money on water bills;
  • Keep your landscaping healthy;
  • Increase your water efficiency;
  • Maximize how effective your sprinkling system is; and
  • Receive a personalized watering schedule

Regular Maintenance

Scheduled inspections of your home can save you from surprise problems. Our plumbers offer an annual plan to come to your home to check for leaks, slow drains, or other potential problems before they start. The Water Resources Division will provide a free home water conservation audit kit to residents of Thornton while supplies last. The kit contains toilet dye tablets, a flow measurement bag, 2.0 gpm showerhead, and other water-saving tools. These kits will help you see where you need to fix leaks or replace high-volume fixtures. You can request your kit at

Repairing Leaks

A simple household leak can turn into a costly problem, especially if it’s happening in a place you cannot see. Not only is this a vast waste of water, but leaks can also cause water damage to your floors, walls, or furniture.

When Should You Call the Water Utility Company in Thornton vs Hire a Plumber?

Most of the time, if you have a plumbing issue in your home or on your land, you’ll need to call our plumbers. As a homeowner, maintenance and repairs to your home are your responsibility. There are a few instances, however, when it’s better to start calling The City of Thornton’s water department.

Water Leakage

A leak on your property is typically the responsibility of the homeowner. However, you’ll have to decide if the leak is coming from your line or the water main. If it’s from the water main or any intake pipes from the street, you’ll need to call the city. If you’re unsure, you can call us first to advise you.

To report a possible water break, call the City of Thornton at 720-977-6500.

Water Pressure Problems

If you discover that you’ve lost water pressure in your home, you’ll need to check around your house first. Do you have an obvious leak or broken pipe? 

If not, there may be a problem within the city water lines. If you’re worried about fluctuating water pressure in your home, you can submit a My Thornton request for service and a field test will be scheduled within 24 to 48 hours. 

When Do You Need Permits for Plumbing Service in Thornton?

Thornton is part of Adams County, so in addition to city guidelines and permits, there are some regulations regarding plumbing that are dictated by the county as well. That said, you need a plumbing permit for many larger projects, especially when building a new home or altering the plumbing or structure of an existing home. These include:

  • Installing or replacing a water heater or boiler;
  • Anything that involves your home’s gas lines;
  • Installing a new toilet, sink, bathtub, shower, or urinal;
  • Installing an automatic sprinkler system; and
  • Placing new drains for wastewater

Our plumbers will take care of applying and paying for permits for you. In most scenarios, this service will simply be added to your bill. If you need to apply for permits on your own, Adams county has an E-permit website for self-service.

Smaller plumbing jobs don’t usually require a permit. If you’re just planning to replace any minor part that doesn’t change the basic function of your appliances, it can be done without applying for costly permits. This includes simple leak repair, replacing outdated or inefficient fixtures, and replacing individual sprinkler heads on your property.
