How to Replace Sprinkler Valve Manifold

How to Replace Sprinkler Valve Manifold?

If you are new or have already been in this field for a long in the irrigation world, then welcome you here. I think you already came to know Sprinkler Manifold is the heart of any irrigation system.

Who still doesn’t know what this is about? The sprinkler manifold is the assembly where valves are located; it turns and off or watering zone.

From time to time, every irrigation system will eventually need repairs and many times need complete renovation.

If your system needs renovation, then you will likely be replacing a valve manifold. Here, in this article, I am going to learn how to replace sprinkler valve manifolds.

Steps need to follow for replacing the sprinkler valve manifold

First of all, you need to know the outer structure of the valve manifold. Let me tell you, a valve manifold is a collection of irrigation valves assembled together which is connected to a common supply line.

Here is another thing that is connected if yours is drip irrigation; the manifold also includes a pressure regulator and a

  • Before you are going to build a new manifold first thing is to do checking the current assemblies, so go and check first; that will help you to understand what you have to work with.
  • Check it carefully and determine what size and quantity of valves you have going to need.
  • For better work experience, I suggest you draw a rough sketch that will help you to figure out the materials you will need to connect the new manifold to the water supply
  • Most probably, you need:

Hunter Drip Zone Control Kits

  1. Valve box
  2. Round valve box
  3. PVC
  4. tees
  5. TSX male adaptor
  6. S cap
  7. Waterproof wire nuts
  8. Solvent cement and
  9. Primer

 

  • The new sprinkler valve manifold includes a flow meter and master valve. Do you know what the work of it is? The flow meter is for monitoring water flow, and the master valve prevents water waste.
  • Now, let’s together jump into the field and start our journey; take your plan paper and switch off the water supply for better safety disconnect the power of the controller.
  • Next, cut the pipe connecting the supply and lateral lines to the manifold also, disconnect the valve wires going to the controller, and label them.
  • Now, the primary work is done. So, you can remove the old assembly and excavate the area-wide and deep according to your new valve box.
  • You are going to install the flow meter. First, this flow meter needs to install between the water supply and master valve.
  • You also need a female adaptor to connect the flow meter and another to the downstream side for the leading master valve.
  • This is not finished yet; you have to follow the same procedure for the master valve except the use of two male adaptors to connect to the PVC pipe.
  • Let’s move to the main manifold with proper planning, and you can assemble parts and then connect the entire unit to the supply and lateral lines.
  • After that, Hunter drip zone kits need to connect with the male adaptor in the master valve. Later cut the pipe with accurate measures that fit into the valve box.
  • The next important step is to connect the unit to supply and lateral lines; you can use brick or something to support the weight of the manifold when you weld the line.
  • Once the connection is made and glue set up, make sure valve solenoids are in the off position.
  • Now, you need to slowly turn the water supply back on to test if it leaks. Then, flush out each zone.
  • At this point, you can connect the solenoid wires to the controller as well as the wires from the master valve.
  • In the final and last step after the wired, test each zone using the controller’s manual operation, and if all is good, add the valve box.
  • Congrats, you are done with your work.

I think if you follow my instruction, then you got already the results. So, it’s happy time now you know how to replace sprinkler valve manifolds.

How To Replace A Sprinkler System Valve Manifold

FAQ

1. Why do you glue a coupling onto the first zone valve, a short piece of pipe?

If you don’t want to do any more digging, then you can be glued in the coupling and a short piece of pipe to get the tee away from the sidewall of the trench.

2. Are these PVC glued pipes standard to use in the US, or is it just cheap?

PVC pipes are used in the pool plumbing’s here as they are huge 2″ more, and these huge sizes are very pricey in hope, but this pipe, I am pretty sure, is still the most common pipe used in the sprinkler system. Usually, the PVC schedule 40 pipes are usually used most. I think using this pipe will save your time as you don’t need to search which pipe you need for work.

3. Is the width of the connection is need to be known before buying a new valve?

Yes, it is important to know if you don’t check the correct measurements.

Because if you do not check it properly later, the valve box will not fit properly.

The valve box protects your wires and other connection from outer darts and keeps them safe and workable.

So, just check correctly and buy according to those. I personally recommend you do that if you don’t want to take any issues later.
