Things You'll Need:
- Sprinkler system (vary by manufacturer)
- Measuring tape
- Hacksaw
- Shovel
- Spade or trenching tool
- Stakes
- String
- Solvent cement
- Level
- PVC pipe
- Stop-and-waste valve
- Control valves
-
Step 1
Lay out the lines for the sprinkler system with stakes and string. Dig trenches by removing sections of sod and placing aside, then dig 6 to 12 inches(dependent on the severity of frost in your area). Make sure trenches are level.
-
Step 2
Place 3/4-inch PVC pipe in the trenches. Join sections with solvent cement. Insert 3/4-by-1/2 inch reducing tees for each sprinkler head every 7 to 10 feet apart. Assemble a manifold with control valves to be attached to the water supply line to route water to the lines.
-
Step 3
Install sprinkler heads on tees. Make sure heads of sprinklers are flush with the tops of the trenches. Consult the manufacturer's manual for your sprinkler system for proper head installation.
-
Step 4
Tap into the water supply line in your garage or basement by installing a tee just past the water meter. Drill an exit hole through the masonry. Install a shutoff valve and a stop-and-waste valve for emergency purposes as well as a means to drain the system in the winter. Attach pipe to manifold.
-
Step 5
Wire the control box to the control valves. Test system. Refill trenches by fitting sod around the sprinkler heads.
