Connecticut Administrative Code › Title 19 - Public Health and Safety › 13-B › Chapter II - ENVIRONMENTAL HEALTH › Swimming Pools and Bathing Places › Section 19-13-B45 - Minimum requirements for drainage and toilet systems

Current through July 10, 2024
(a) Plumbing and drainage systems shall be so
				  constructed as to avoid contamination of safe drinking water supplies in houses
				  or buildings. There shall be no cross connections between such safe water
				  supplies and unsafe water supplies nor shall such safe supplies be piped to
				  refrigeration, air conditioning or other mechanical equipment provided with
				  direct connections to drains or constructed in such a manner as to permit
				  contaminated water to be siphoned or drawn into the water supply pipes. Storage
				  of drinking water in buildings shall be only in covered tanks so constructed as
				  to avoid any possible contamination of the water in the tanks. Sewer or waste
				  lines located above storage tanks and direct overflows and drains to sewer
				  systems are expressly prohibited.
(b) Buildings in which water closets and
				  other plumbing fixtures exist shall be provided with a supply of water adequate
				  in volume and pressure for flushing purposes.
(c) The pipe system shall be of sufficient
				  size to supply water for adequate flushing of toilet fixtures without unduly
				  reducing the pressure at other fixtures.
(d) Devices for heating water and storing it
				  in "boilers" or hot water tanks shall be so designed and installed as to
				  prevent all dangers from explosion.
(e) Each tenement, lodging or boarding house
				  located on premises abutting any street or alley where running water is
				  available and through which there is a sewer with which connection may be had
				  shall be provided with water closets connected with such sewer. All other
				  buildings used or intended to be used for human habitation or occupancy on
				  premises abutting a street in which there is a public sewer shall be connected
				  with such sewer whenever required by the local authorities having
				  jurisdiction.
(f) Tenement houses
				  erected prior to September 1, 1930, and provided with house drainage systems
				  shall be furnished with at least one water closet for each two apartments of
				  three rooms or less each, and one such closet for each apartment of four or
				  more rooms. Tenement houses erected after August 31, 1930, and prior to July 1,
				  1941, shall have a water closet in each apartment of three or more rooms and at
				  least one water closet for each two apartments of less than three rooms each.
				  In each tenement house erected or subdivided after June 30, 1941, there shall
				  be a water closet in each apartment of two or more rooms.
(g) Plumbing fixtures shall be made of smooth
				  nonabsorbent material, shall be free from concealed fouling surfaces and shall
				  be set free of enclosures.
(h) The
				  entire house drainage system shall be so designed, constructed and maintained
				  as to conduct the waste water or sewage quickly from the fixture to the place
				  of disposal with velocities which will guard against fouling and the deposit of
				  solids and will prevent clogging.
(i) The drainage pipes shall be so designed
				  and constructed as to be proof for a reasonable life of the building against
				  leakage of water or drain air due to defective materials, imperfect
				  connections, corrosion, settlements or vibrations of the ground or building,
				  temperature changes, freezing or other causes.
(j) The drainage system shall be provided
				  with an adequate number of cleanouts so arranged that in case of stoppage the
				  pipes may be readily accessible.
(k) Each fixture or combination fixture shall
				  be provided with a separate, accessible, self-scouring, reliable water-seal
				  trap placed as near to the fixture as possible.
(l) The house-drainage system shall be so
				  designed that there will be an adequate circulation of air in all pipes and no
				  danger of siphonage, aspiration or forcing of trap seals under conditions of
				  ordinary use.
(m) The soil stack
				  shall extend full size upward through the roof and have a free opening, the
				  roof terminal being so located that there will be no danger of air passing from
				  it to any window and no danger of clogging of the pipe by frost or by articles
				  being thrown into it or of roof water draining into it.
(n) The plumbing system shall be subjected to
				  a water or air-pressure test and to a final air-pressure, smoke or peppermint
				  test in such a manner as to disclose all leaks and imperfections in the
				  work.
(o) No substances which will
				  clog the pipes, produce explosive mixtures or destroy the pipes or their joints
				  shall be allowed to enter the house drainage system.
(p) Refrigerators, ice boxes or receptacles
				  for storing food shall not be connected directly with the drainage
				  system.
(q) No water closet shall
				  be located in a room or compartment which is not properly lighted and
				  ventilated to the outer air.
(r) If
				  water closets or other plumbing fixtures exist in buildings where there is no
				  public sewer accessible, suitable provision shall be made for disposing of the
				  sewage without nuisance. The location and construction of private sewage
				  disposal systems shall conform to the requirements of sections 19-13-B20a to
				  19-13-B20r, inclusive.
(s) Where a
				  house-drainage system may be subjected to back flow of sewage, suitable
				  provision shall be made to prevent its overflow in the building.
(t) No plumbing fixture nor waste outlet
				  shall be installed which will provide a cross connection between a distributing
				  system of water for drinking and domestic purposes and a drainage system, soil
				  or waste pipe and permit or make possible the back flow or siphonage of sewage
				  or waste into the water supply.
Note: Attention is directed to the danger from underrim
					 water inlet fixtures and flushometer valves without adequate vacuum
					 breakers.
(u) All drinking
				  fountain installations or replacements after January 12, 1954, shall be
				  constructed with a slanting jet issuing from a nozzle of non-oxidizing
				  impervious material with a non-oxidizing guard to prevent the mouths and noses
				  of persons using the fountain from coming in contact with the nozzle. The jet
				  shall be located so as not to touch the guard and shall be discharged at such
				  an angle that the water can neither fall back nor be forced back on to the
				  point of discharge. The fountain jet and all openings in the water supply
				  piping shall issue above the level of the fountain bowl. The drainage from the
				  bowl shall be adequate and so constructed as to prevent fouling of the bowl.
				  The drain from the fountain shall not have a direct physical connection to a
				  waste pipe unless the drain is trapped. The waste opening and pipe from the
				  fountain shall be of sufficient size to carry off the water promptly. The
				  opening shall be provided with a strainer. All drinking fountains installed
				  after January 12, 1954, shall be provided with their own receiving bowls and
				  shall not be installed over sinks used for hand washing or other
				  purposes.
(v) Plumbing systems
				  shall be maintained in a sanitary condition.
