Residential Customers

Cross-connections can occur in private residences when garden hoses are left submerged in pools, when they lay in elevated positions above the hose bib, or when chemical sprayers are attached to hoses to spray pesticides.

Hoses should be disconnected promptly after use, and the installation of hose bib vacuum breakers is strongly recommended. These simple devices are available at many hardware, plumbing and builder's supply stores and range in cost from $5 to $15.
