9 - PLUMBING 30. Waste & Venting of Fixtures: Original plumbing must conform to Plumbing Code in effect at time of the construction of the building. All other plumbing installed at a later date must conform to present codes. The condition of any plumbing hidden within a 'finished wall can only be surmised (sometimes it might be necessary to gain access in order to ascertain its condition). Waste lines which are leaking or improperly patched must be replaced. Waste piping which is of a pleated flex type is not approved and must be replaced. Any open and unused waste lines must be properly sealed. Laundry tubs/sinks which drain directly into floor drains because of insufficient waste/vent piping must be properly wasted and vented to code. Plumbing Fixture Abandonment: When basement waterclosets and shower drains are removed, all waste lines must be properly sealed/capped below basement floor level . All such abandonments should be inspected before sealing floor with concrete. Waterclosets abandoned on upper floors must have closet waste arm removed to soil stack and properly sealed and inspected. Water Piping: Half-inch water distribution pipe is acceptable if it is part of the original construction and all plumbing fixtures can maintain a minimum flow rate as defined in the housing evaluation guidelines. Undersized water piping shall be acceptable for purposes of this housing inspection program only. All future -remodeling which includes plumbing, modifications or additions, shall meet current State of Minnesota Plumbing Code requirements. 31. Water Pressure and Rate of Flow: To determine minimal waterflow. rate, turn on the water at the lower fixture (laundry tub, etc.) . Then, turn on the water at the highest fixture in the house. If, during the entire length at the test, a steady uninterrupted stream of water approximately one quarter inch (1/4") to three-eighths inch (3/8") is maintained, NO corrective action is required. Cleanouts: Waste stacks must have cleanouts, and cleanouts must be accessible. Main sewer cleanouts located below the basement floor must be extended up two inches above the basement . floor with a full wye branch fitting. The floor opening around the new extended cleanout must be filled with sand and a 3-inch cement cover level with the . basement floor. Plugs: Any washer standpipe waste line not in use must be at least temporarily tightly plugged until put into use. Floor drains require that their cleanout by-passes ..have an appropriate cleanout . plug (and also a cover grate which is in one piece) . Floor drains must be operational with the cleanout plugs in place. A floor drain which is never used should be properly abandoned and capped. 32. Backflow Preventers : No requirement except for automatic lawn sprinkling systems, and water feedline to 'boilers, which must be equipped with approved back siphonage/backflow protection devices.
