System Overview - How Our Bed is Watered
STEP – BY- STEP
Build Your Drip System
Plan and Measure
Plan the water source, trench, and riser location, keeping the route as straight and simple as possible.
Dig the Trench
Dig a trench from the water source to the raised bed, deep enough to protect the PVC line.
Measure & Dry-Fit the PVC
Measure, cut, and dry-fit the PVC first, making sure all fittings and the riser line up before gluing.
Prime & Glue the Joints
Prime and cement each PVC joint, one connection at a time, keeping everything aligned.
Tools & Materials
Sprinkler box connection (with 1/2" MPT adapter)
PVC pipe (1/2-inch)
Tee connectors and elbows (1/2-inch)
End cap (1/2-inch)
Shutoff valve (1/2-inch)
PVC primer & cement
Standpipe / riser (1/2-inch)
Hose adapter (1/2-inch MHT)
Filter (120 mesh recommended)
Pressure regulator (25-30 PS)
1/2-inch poly tubing
Hose adapter (1/2-inch MHT)
Stakes or clips to secure tubing
Optional Premade Route
Tip: Flush your system before final assembly to clear out any debris.
Install the Riser into the Bed
Bring the feed line up inside the bed with a vertical standpipe (riser). Cut to height and add a threaded cap on top.
Build the DIY Grid
Lay out 1/2″ poly tubing in a grid using tees and elbows, then cap the ends. Mark holes about every 3 inches and carefully drill with a 1/16″ bit, avoiding fittings.
Add Filter & Attach Grid
Once the fit looks right, prime and cement the PVC joints. Work one connection at a time and keep the orientation correct.
Test, Mulch & Plant
Once the fit looks right, prime and cement the PVC joints. Work one connection at a time and keep the orientation correct.
Quick Tips
Flush the line before final assembly.
Keep pressure regulated (25-30 PSI).
Clean the filter screen regularly.
Stake or clip tubing to prevent shifts.
Test for leaks before covering or mulching.
Why This Layout Works
Buried PVC gives a durable supply line
