Building and installing your own PVC sprinkler system does not have to be as difficult as you may imagine. While most homeowners decide to have help in fitting their system, you can also build and design it yourself without any major difficulties. If you look at the position of your sprinkler in relation to the rest of the home, then you should be able to install it yourself. The first part of this process will look at planning, building and installation set-up of your PVC sprinkler system, and the second part will look at the actual installation of the system into the garden.

    Step 1 - Plan your Installation

    You need to work out how to spray the largest area without touching windows and doors, and without having water spray onto a local path or public area. Measure the garden, and use a piece of string to measure the length of the spray. By placing the sprayer in one location using a peg, and then moving around in a circle, you should be able to spot any problems with the position of the sprayer. Make a final decision about where the spray mechanism should be installed. As well as measuring the outward reach of the spray, you will also need to place the PVC spray system into a location where you can attach a power outlet, and the water valves which will control the action of the sprinkler system.

    Step 2 - Plan your Materials

    Once you know the extent of your spray field, you can begin to work out the right materials for your build. Choose lower schedule PVC pipe work, as this will be more cost-effective and the final result will not affect your sprayer. Choose a suitable solenoid valve, such as the above-ground valve, as this can be connected to the PVC pipe easily, and as it is above ground you will be able to address any problems in the design easily.

    Step 3 - Lay out your Sprinkler System

    You should now place the sprinkler heads for your PVC sprinkler system around the garden. You should then use your digging tool to lay out a series of trenches, around 1.5 to 2 feet deep. You should then be able to dig out the inside of the trench, particularly when you come to the main spray system supply line. Once the sprinkler trenches have been dug, you can have a tap fitted into the main sprinkler line.

    Step 4 - Installing the Main Line

    Once the tap has been fitted, place in a vertical tee. Fit the tee, and then add a small piece of pipe, about half a foot in length, between that and the next tee. This will allow you to have a suitable space between the 2 valves. Take more pipe, and fit it onto the tee. At the other end of the valve, install your solenoid valve. You are now ready to install the rest of your PVC sprinkler system.
