“Water lines” can refer to fresh water or waste water. On this page, we are referring to the outside pipes that bring fresh water from the city’s main line into your home. The industry terminology calls this “water service”. For more information on inside water lines, see our Repipe Services page.

To ensure water is delivered when wanted, your water service is kept under constant high pressure.  As a result of this pressure, leaks can develop in weak or older pipes.

Signs of Trouble

An elevated water bill is the most common, and often the only symptom of a leak in your water service. Sometimes, when a leak occurs, water will find its way onto your lawn or basement, whichever is downhill from the leak. Because uncontained water can be so damaging, we recommend locating your water shut off at the water meter before an emergency arises.

With this in mind, look for these signs of trouble:

  • An unusually high water bill
  • The water meter running when no water is in use
  • Standing water found on the lawn, walkway, sidewalk, or driveway
  • Water in the basement or on the lower level of your home

Furthermore, a water service may fail due to old age, the type of pipe, or the presence of tree roots. When a tree needs water, it can wriggle its way inside the smallest cracks in a pipe.  In time, the pipe can break open and become an emergency situation.

Call Raymark Plumbing and Sewer at 206-430-9077 if you suspect a water line is leaking.  We will make recommendations to repair or replace part or all of the water line.

In an Emergency

If an outside pipe is leaking or flooding, turn off the water at the water meter.  Check for a water shut-off valve at the water meter box near the street.

  • If you have a Top Shut Off (TSO) meter, you may be able to shut the water off with your hands or with a wrench
  • Older meters may need a special tool to shut off the water. If you need help to shut off your water at the meter, call Raymark at 206-430-1954 , or call Seattle Public Utilities at 206-386-1800.
  • See this Seattle Public Utilities link on How to Shut Off Water At the Meter
  • If you find water running on a neighboring property, call the Seattle emergency line at 206-386-1800.

Raymark plumbers have all the tools needed to shut off your water and to make repairs.  Call us for any problems with water in your lawn, driveway, yard, patio, and home. Our expert and knowledgeable technicians can solve the problem and stop water line leaks.

Water Pressure

Some Seattle area neighborhoods are known to have consistently high or low water pressure.

  • In neighborhoods with high water pressure, Raymark can install a PRV (a Pressure Reducing Valve).  This valve regulates the water pressure, reduces the pressure on the water line, and increases the life span of the pipe.
  • Neighborhoods with low water pressure are usually located at the bottom of a hill. For these locations, Raymark may recommend a booster pump to increase the flow.

Water Line Composition

The city main water lines run under the street and are maintained by Seattle Public Utilities. These lines are made of copper, plastic, galvanized iron, or ductile iron.

Use this link to find out what your city water line is made of. Further, the water line from the city water meter to the home is the Seattle homeowners responsibility.

Water Line & Water Service FAQs

  • How would I know if I need a water service repair?

    A repair may be needed if your water lines are leaking. The usual symptoms of a leak in your water service are:

    • an unusually high water bill
    • the water meter running when no water is on in the house
    • puddles in the yard or on the sidewalk when not raining
    • sound of water running
    • green grass when all other grass is yellow or brown
  • How do you determine when to shut off the water at the meter or in the house?

    Shut off the water in the house when leaking or flooding occurs inside the house.  Many sinks and toilets have water supply lines, so you can isolate water shut off at those points, or at your home’s shut off valve.

    If water is leaking or flooding outside the house, shut off the water at the water meter. This will turn off all water to your home.


    review rating 5  As a preventative measure I had the old rubber hoses upgraded to metal hoses for my washer plus, installed new hot & cold faucet seats. Tanya took my incoming call and she was most pleasant and professional. Though this was elective and not urgent, plumber Jose had time to come out same day. The office called me two more times to advise me Jose would be at my condo within 30 minutes. Jose and his partner evaluated my request and gave me a quote. I elected to proceed. Jose completed the work perfectly in one hour. The space was left clean and tidy and my washer / dryer put back in place. Cost? Well, let me just say this. Any young man floundering in college with no apparent purpose, racking up enormous student loan debt, consider a plumbing apprenticeship. You will have a most comfortable income. I appreciate professional trades people.

    review rating 5  Highly recommend! Raymark has been taking care of my home for 12 years. I bought an older condo and as the original equipment has needed repairs or outright replacements since day one. They have been prompt, reliable, solid workmanship, competitive and so professional. The materials and equipment they use is high quality and still appropriate for my budget. Reputable billing. Never once stood me up, and stand by their work. Never a callback. And they are careful with my home. My go-to company. I’m a very happy customer.

    review rating 5  This awesome company came out and cleared our sewer main in no time flat. Dion was courteous, competent, professional, reliable, and did a beautiful job! It is important to me that we hire local, and the truth is, you just get better service! Also, it is important if you don't have a lot of time in your day that you choose a company that will actually show up, and show up when they say they will, and have efficient office staff to help as well. Raymark also provide their employees with benefits, which is SO important! It made me feel glad to support their business, and they are my go-to from here on out. Beautiful service! Please give them a try!
