Locate the main shutoff valve on your irrigation system. It is between the main water supply to your home and the sprinkler controller. Alternately, the main shutoff is located outdoors near a faucet bib. The main valve may be in a box in this area to protect it from the elements.
If manual cleaning is not performed immediately, instruments should be placed into a container and soaked with a detergent, a disinfectant/detergent, or an enzymatic cleaner to prevent drying of patient material and make manual cleaning easier and less time consuming.
Mouthpieces should be cleaned at least once a month to remove build up. The inside of the instrument should be swabbed after every session, and the outside deserves polishing every month or so to wipe away dirt, grime, and water residue. Pieces should always be hand-washed with non-abrasive cleaning agents.
