This is to advise you that it is unsafe and unlawful to make or permit any type of cross connection between the District water system and any other system. The sketch below illustrates a cross connection.
Please review and if you have a cross connection disconnect the two systems to avoid polluting the District water supply.
On many lines the water pressure will be in excess of that usually furnished by well systems. This is necessitated because of the variation in terrain (low valleys and high ridges).
In order to have uniform pressure in your house system and avoid inconvenience and possible damage to water hose lines it will be necessary to install pressure regulators on each individual service. These regulators may be purchased at your local hardware store or from most of the plumbing companies.
