Abstract
An integrated check valve/strainer-filter assembly that combines a check valve with a strainer-filter assembly in a compact structure is provided. The novel assembly provides the benefits of floor space savings and low maintenance costs. A strainer-filter element may be mounted in a removable strainer-filter housing to provide easy access to the element for cleaning or replacement. The check valve may be installed at one of three desirable positions thus affording additional flexibility of the present invention novel apparatus.
