The price of replacing your main water gate valve is quite arbitrary. The primary gate valve will easily survive 10-15 years. In this instance, taking care of the valve is essential. Gate valves being stuck is a common occurrence. The valve must be replaced as a result of this.

Several factors can influence the cost of the procedure. The valve alone costs from $150 to $300 on average. If there are any extra repairs or replacements, the price might rise to $600.

Gate Valve Installation & Maintenance Instructions

When properly fitted and maintained, gate valves of various materials and seat kinds are simple to use and endure for a long time. For different end connections (e.g., flanged vs. rolling groove vs. Victaulic), the installation procedure somewhat differs , but the other instructions stay the same.

Storage Conditions

Do not package the valves until they are ready for installation to protect the seat and seals. This will shield the valve from dust and debris, which may cause seat leaking in the future. If keeping for an extended amount of time, keep it cool and properly aired.

Valve Installation

  • Valves can be set in any position although it is preferable to install them upright, especially in larger sizes, for easier access to the handwheel.
  • Before installing the gate valve, check the material of the seat and disc. Make sure there aren’t any problems with storage or transit.
  • Complete all welding before installing the valve, and make sure the flange has reached room temperature before fitting the gate valve with the proper gasket.
  • Before installing the pipe, inspect it for welding residue, waste, rust, pickle paste, or other debris. If necessary, wash with water or a light detergent.
  • Make sure that the flange is not warped or the gate valve is not misaligned. When the valve is not properly aligned with the flange/pipe, this is the most prevalent cause of valve difficulties. To lessen the stress on the pipe assembly, support the valve as needed.
  • Install the spacing bolts with care to avoid damaging the valve seat, and position the face to face of the two flanges so that room is available when the pipe is stretched open (enough space to slip the valve in or out for service).
  • Insert the bolts such that the bottom of the valve rests on them to prevent the valve from falling through after the pipes are centered.
  • Tighten the bolts one at a time, in phases, to provide consistent pressure and a seal between the valve, gasket, and flanges.
  • After the installation is complete, test the valve to ensure it has not shifted throughout the process.

Field Testing

Gate valves with a rubber seat are only meant to hold rated pressures. In the closed position, test pressures over the rated operating pressure can harm the valve. The pipeline can be tested up to the valve hydrostatic test pressure with the valve in the open position. Foreign material jammed between the seat and the body might cause the seat to leak. If this happens, open the valve 10% to 15% to get a high-velocity flushing action. If required, close and repeat.


  • Use the valve only at pressures below the operating pressure.
  • Check the valve face and seat if the valve is stuck halfway between open and closed. Remove any strange things and inspect them (see maintenance).
  • Actuators with too much torque might harm internal valve components.


  • If the valve isn’t used frequently, cycle it at least once a month.
  • Before doing any maintenance, lower the system pressure.
  • Reverse the installation procedure to remove the piping.
  • Remove the top body (bonnet) and stem from the valve gate and replace it. Remove the gate and replace it with a new one. Refit the top of the body into place.
  • For further information, see the video links under each gate valve model like this video.

Design Guidance and Product Advantages

  • Always consider the available space for handwheel operation while sizing the valve.
  • To bear extra weight, consider using valve supports.
  • On request, 316 stainless steel extension shafts are available. This will allow the valve to be installed in a pit and operated above ground.
  • The bodies of these valves are made of Ductile Iron for additional robustness. Low torque operation and a long maintenance-free operating life are provided by high-finish molded seats.

Factors That Can Affect Your Main Gate Valve Installation Costs

Several factors might influence the cost of replacing your gate valve. When making your budget, keep these things in mind.

Type of Valve

There are many different types of valves to select from. Although the ball valve is the greatest in terms of quality, we recommend obtaining it. The type of valve you select can influence the ultimate cost. Before making a final selection, it’s critical to understand how each type of valve operates.

Plumber Costs

If you’re not experienced with such situations, get a plumber to assist you. A plumber would be able to assess your home’s situation and recommend the best remedy.

A plumber might cost anything from $150 to $1,000. This is determined by the nature of the task, the availability of resources, and your geographic location. For a more accurate estimate, contact your local plumbers.

The severity of the Work

What’s the state of your gate valve? Is the environment around it in excellent shape? Are there any additional repairs or replacements you require?

These are critical issues that must be addressed. Your costs might skyrocket if you have a leaking pipe or any damaged pieces. Make sure your system is in good working order before you start.

Location of your Valve

The main water valve is easy to locate. Follow the main water line of your house until you notice a knob or lever. It’s most likely in your house’s basement or an outside wall.

Finding the valve in an older house may be more difficult. In such a situation, if you hear the water moving through pipes but no leaks, you can proceed.

A ball valve is usually installed in your home. A gate valve may even be present in an older home.

The ultimate cost might be affected by the position of your valves. It will be more costly if it is more difficult to locate.


Look around for any signs of rust once you’ve located your valve. Look around your valve for any kind of residue. There’s a potential that your valve is rusted if the residue doesn’t come off. It needs to be replaced.

If your valve has rust, likely, other elements of your system have as well. And you’ll have to fix the complete system, which will increase the expense.

Depending on additional conditions, the cost of replacing a complete system can reach $2000.

Gate Mechanism

To check the condition of the valve, switch it on and off a few times. It might be troublesome if the valve is stuck or keeps rotating. It might have deteriorated and needs to be replaced right now. A faulty gate mechanism might also increase your costs.

Required Tools

If you’re used to working with domestic plumbing, this isn’t a big deal. If you’re starting from scratch, though, you’ll need certain tools. Wrench, lubricants, and other household tools are required. If you don’t have these tools, you’ll need to get them. The cost of tools might also raise the eventual cost of replacement.
