    Residential Water Line

    The main water line is the pipe running underground your property supplies to the smaller water pipes. If the main water line is damaged, it can cause severe damage to the property’s structure.

    Let’s say you are renovating and need to add a new kitchen or a bathroom to the structure. In this case, you’re more likely to have to google “water line installation near me”. In addition, if the main pipe is damaged, it can cause issues like flooding in your house and swampy yard conditions.

    Underground water line installation is a task that is best left to a professional main water line installation company. Such professional services can deal with installation, repair, and replacement. They will inspect the situation and give you details, such as the water line installation cost per foot.

    Water Line Installations

    Underground water line installation is an extensive process that involves certain steps. Let’s examine the steps and procedures involved in laying down a main water line installation.


    The first step is excavation, which involves digging a path in the ground to lay down the pipe. At this step, certain factors, such as ground frost and groundwater conditions, traffic load over the ground above the pipe, pipe size, soil type, depth of conflicting utility lines, etc., have to be taken into account.

    Expert water main installation services have trained professionals who understand that these factors have to be considered and do the job accordingly.

    Trench Depth

    The trench depth is the narrow excavation below the ground, depending on pipe size, soil, traffic, temperature, etc. The minimum depth to protect the pipe against temperature-related elements differs depending on hot and cold regions.


    Bedding involves leveling and preparing the ground for the PVC pipes. Bedding consists of leveling the bottom of the trench for proper and full-length support for the pipe. Expert teams use leveling boards to ensure no voids or high spots.


    If the natural conditions do not allow for proper bedding, other measures can be taken, such as digging deeper. The haunching process is also used by professionals to place bedding material around the pipe’s haunch to increase the pipe’s load-bearing capacity.

    Laying Pipe

    Once the bedding is done, and the trench is prepared. It is time to lay the pipe. Before this can be done, there are specific steps taken by professional main water line installation services, including inspecting the pipe for damage and cleaning any debris or any other kind of dirt through a hypo chloride solution.


    The best and most expert way to place the pipe is to lay it on the ground by hand or mechanically, and the pipe should be supported in the middle through a sling. Installation teams do this while also ensuring that the pipe remains clean from the inside.

    Joining Pipe

    The next step in a new water main installation process is joining the pipe, and this is a critical step that must be done correctly to avoid any major leaks in the future (often, there are difficulties in detecting and stopping the water). The joining method depends on the material of the pipe and the type of joints.

    Appropriately sized bell holes must be dug by hand at the place where the pipes are to be joined. The size of the bell hole will depend on the type of pipe and joint.

    Push On Joints

    Here is how ductile iron or PVC pipe push-on joints are made:

    The bell socket and the groove of the pipe is thoroughly cleaned
    Lubricant is applied to the gasket and plain end of the pipe
    The plain is beveled to avoid sharp edges from damaging the gasket
    A small pipe is pushed into the bell socket with a long bar
    Installers will use a timber header between the pipe and the backhoe bucket to avoid damaging the pipe

    Connecting To Existing Main Pipes

    Once the main water line is laid down – it has to be connected to the existing main lines, and there are two ways to do this:

    Tee Connections

    For this method, the main water supply has to be shut off, which means there will be no water supply in the property during this time.

    The tee fitting is added to the existing mains.
    A small piece of an existing main is utilized to snap or cut at the location of the main that has to be removed.
    The next cut is made in the middle of the existing mains and the pipe is hit in the center with a sledge for it to break out easily.
    Pressure Taps

    The pressure tap technique is used more widely by expert main water line installation services due to the advantages it offers. These benefits include no downtime for the customers, less probability of water contamination, and no water loss, etc. The following steps are involved in this method:

    The existing main’s surface is cleaned.
    The tapping sleeve is added on to the main with the flange facing up vertically.
    Another tapping valve is added to the previously installed flange.
    The next step involves attaching the tapping machine to the valve with a shell cutter in toe.
    The cutter is propagated in the main pipe to cut a hole in it.
    The cutter is retracted, and the valve is closed.
    The tapping machine is removed, and new main is connected,

    The material used for a water main pipe can vary, but commonly used options include plastic piping, PVC, copper, and PEX (cross-linked polyethylene). Each material has its advantages, with PEX being a popular choice due to its flexibility, durability, and resistance to corrosion.

    The depth of a main water line depends on factors such as local regulations and climate. Generally, water mains are buried at a depth ranging from 18 to 60 inches. In areas with freezing temperatures, the depth is often increased to prevent pipes from freezing and breaking.

    The lifespan of main water pipes varies by material:

    • Cast Iron and Ductile Iron: 75 to 100+ years.
    • Galvanized Steel: 20 to 50 years.
    • Concrete and Asbestos Cement: 50 to 70 years.
      • PVC: 50-100 years.
      • HDPE: 50 to 100 years.
