Where are cross connections found?
A cross connection exists wherever the potable water supply is connected to a plumbing fixture. However, most new fixtures have built-in protections to avoid a cross connection. Commonly found cross connections can occur in hose spigots, irrigation sprinkler systems, boilers, swimming pools, fire sprinkler systems and auxiliary water supplies.
