Structural Considerations for Theatre Plumbing

Installation of the Following Facilities Should Conform with Codes and Standard Practices

BRIEF: Satisfactory plumbing and toilet facilities are the indispensable requisites of all public assembly places . . . aml the motion picture theatre is certainly no exception . . . The patron does not want

to encounter shabby and malfunctioning equipment when he visits the washroom . . . Customer satisfaction is easily attained on this score . . . by proper installation, drainage, and ventilation.


If up-to-date technical knowledge and the experience acquired by other operators are studied; and if building codes are strictly observed, the usual headaches in theatre plumbing systems can be avoided and costly repairs eliminated. The following information, prepared especially to promote successful installation and maintenance of the plumbing and toilet departments, supplements

data presented on pages 151 and 152 of the 1947-1948 THEATRE CATALOG.

Drainage and Sewers

The general rules which apply to the installation of a firsteclass plumbing job hold true for the theatre, and the layout so far as pipe sizes, connections, venting, etc., are concerned, should follow standard accepted practices and code requirements.

If the level of the basement is below the street sewer, then a sump pump to take care of basement drainage is indicated; also if the lowest toilet fixture is below the sewer, then an ejector pit is required with the necessary check and back water valves. Dual pumps for the ejector afford good insurance and are especially desirable in case of heavy rains or flash floods, when no separate storm sewer outlet is available.

A theatre roof necessarily covers a large expanse and during heavy rains is capable of collecting a large amount of water which must be disposed of, through sufficient leaders, by the street sewer. If no storm sewer connection is available, these leaders should connect with the sanitary sewer, through a common leader, on the street side of a back Water valve, to prevent backing up of the sewage and dooding through the lower toilet fixtures.

Roof leaders should be equipped at the roof with a substantial type of roof drain which will permit the free passage Of Water without stoppage by dirt or refuse, and which can easily be cleaned. Roof drains should also have, provisions for necessary flashing under the roofing t0 prevent leakage at these points.
