Directions:

1. Mount the pump on the plastic tank.

Select a pump based on your lawn size. A 25 to 30-gallon tank with a standard 12-volt pump is usually efficient for areas up to two acres.

Mark and drill holes in the tank to attach the pump securely using screws and flush nuts.

2. Install the pressure-relief valve.

This valve controls the spraying pressure and directs excess liquid back to the tank. Install it by drilling a hole atop the tank, using Teflon tape on threads to prevent leaks, and attaching it with screws, nuts, and a hose to the barb inside the tank.

3. Install the inline filter.

To prevent blockages, drill a hole near the pump to fit the inline filter. Secure it with Teflon tape and hose clamps, connecting it to a feeder tube inside the tank.

4. Build the boom.

Construct the boom using a PVC hose, aluminum pipe, a nozzle kit, and clamps. Cut equal pieces of PVC hose to match the nozzle length, attach spray tips to the nozzles, and secure them to the aluminum pipe, ensuring even spacing for efficient spray coverage.
