Things you will need: 

[ 1 ] A gas powered pressure washer 1900 PSI or above
[ 2 ] wet - dry vac
[ 3 ] 0 % nozzle 
[ 4 ] The Hydrovac Attachment 

Assembling the Hydrovac Attachment is as Easy as 1-2-3!

 1 :  Clip the pressure washer wand into the smaller side of the base of the attachment.

2 :  Slide the nozzle cap over the top of the wand, and secure into place to the base. Slide the attachment so the tip of the wand is recessed in the top.

3 :   Slide the vacuum tube into the larger side of the base of the attachment.  Snap the wand into the included hose clamp and clip the hose into place.

Now you are ready to begin excavating! 

Usage Tips

When you begin, be sure to keep the tip of the wand as close to the ground as possible. Be sure to release the trigger before removing the tip from the hole. This will reduce the amount of over spray.

As always, safety first!  Call 811 Before You Dig, and use proper safety equipment as outlined by pressure washer and wet - dry vac manufacturers!
