Section 890.1910  Inspections

 

A plumbing system or any part thereof shall not be enclosed, covered up or used until the system has been inspected and approved by a plumbing inspector.  It is the responsibility of the licensed plumber or plumbing contractor on the job to arrange for inspection by the Department or a local plumbing inspector.  The plumbing inspector may require tests as listed in Section 890.1930 to determine whether or not the system as installed is in compliance with this Part. Plumbing found not to be in compliance with this Part shall not be approved.  A plumbing system not complying with the provisions of this Part shall not be used until such time as it is brought into compliance with this Part.  After the plumbing corrections have been made, the plumbing contractor shall arrange for reinspection.

 

Section 890.1920  Testing of Plumbing Systems

 

Defective Plumbing.  Where there is reason to believe that the plumbing system fails to comply with this Part, the Department or local plumbing inspector may require such tests (see Section 890.1930) and inspections as may be necessary to assure that any defects are found and corrected.

 

a)         Exposure of Work.  When plumbing work has been covered or concealed prior to being tested and approved, it shall be exposed for testing. It is the responsibility of the licensed plumber or plumbing contractor to expose plumbing for inspection purposes.

 

b)         Equipment, Material and Labor for Tests.  All equipment, material and labor required for inspection and testing a plumbing system or any part thereof is the responsibility of the licensed plumber or plumbing contractor.

 

Section 890.1930  Test Methods

 

a)         Roughed-In Plumbing.  The piping of plumbing drainage and venting systems shall be tested upon completion of the roughed-in piping installation by water or air to prove watertight.  The Department or local plumbing inspector may require the removal of any cleanout plugs to ascertain if the pressure has reached all parts of the system.

 

b)         Water test.  The water test shall be applied to the drainage system either in its entirety or in sections after piping has been roughed-in.  If applied to the entire system, all openings in the piping shall be tightly closed, except the highest opening, and the system shall be filled with water to point of overflow.  If the system is tested in sections, each opening shall be tightly plugged except the highest opening of the section being tested and each section shall be filled with water; however, a section shall not be tested with less than a ten (10) foot head of water.  In testing successive sections, at least the upper ten (10) feet of the next higher section shall be tested, so that every joint or pipe in the building (except the uppermost ten (10) feet of the system) shall be submitted to a test of at least a ten (10) foot head of water.  The water shall be kept in the system or in the portion being tested for at least 15 minutes before inspection starts; and inspection or testing of the system shall confirm that the system is tight at all points.

 

c)         Air test.  An air test shall be made by attaching an air compressor testing apparatus to any suitable opening and after closing all other inlets and outlets to the system, forcing air into the system until there is a uniform gauge pressure of five (5) pounds per square inch (p.s.i.) or sufficient to balance a column of mercury ten (10) inches in height.  This pressure shall be held without introduction of additional air for a period of at least fifteen (15) minutes.

 

d)         Water Supply System.  Upon completion of a section, or the entire water supply system, the system shall be tested and proved tight under a water pressure at least one and one-half (1 ½) times the system pressure but at least 100 p.s.i., by air or water.  When exceeding 100 p.s.i., the test shall be of the hydrostatic type only.  Testing pressure shall be maintained for 15 minutes.  The water used for this test shall be from a potable water supply.

 

e)         Finished Plumbing.  After the plumbing fixtures have been set and their traps filled with water, their connections shall be tested and proved gas and watertight.  The test for gas and water tightness of the completed drainage and vent system shall be made by filling all traps with water, and then introducing into the system a pungent, thick smoke produced by one or more smoke machines.  When the smoke appears at stack openings on the roof, the stack opening shall be closed and a pressure equivalent to a one (1) inch water column shall be maintained for the period of the inspection.  Where the Department or local plumbing inspector finds that a smoke test cannot be performed, a peppermint test may be substituted.  A peppermint test is conducted by introducing two (2) ounces of oil of peppermint into the roof terminal of every line or stack to be tested.  Immediately after the oil of peppermint is introduced into the system, ten (10) quarts of hot (160 degrees F.) water shall be added, and each terminal sealed.  The detection of the odor of peppermint at any trap or at any other point in the plumbing system denotes a leak.  Individuals whose body or clothing have come in contact with oil of peppermint shall be excluded from the area until the test is completed.

 

f)         Building Sewer.  The building sewer shall be tested by insertion of a test plug at the point of connection with the public sewer.  The building sewer shall be filled with water under a head of at least ten (10) feet of water.  The water level at the top of the water column shall not drop for at least 15 minutes.

 

Section 890.1940  General Administration

 

The plans and specifications for a plumbing system whose design does not comply with this Part must be submitted to the Department for approval prior to installation of such a plumbing system.  Such approval shall be in writing from the Department and shall be based on a determination that the system is expected to perform and exhibit durability as if meeting the requirements of this Part.

 

Section 890.1950  Violations

 

a)         Notice of Violation

 

1)         Violators of this Part shall be informed of any violation at the time of inspection, followed by a formal notice in writing, including a deadline date for correction of the violation(s).

 

2)         Factors to be considered in establishing deadline dates for correction shall include the nature and complexity of the violation, the stage of construction, the type of violation involved, the weather, and whether or not the violation represents a potential or immediate health hazard.

 

b)         Reinspection.  Upon receipt of information from the violator indicating correction of violations or upon expiration of the established deadline date, a reinspection shall be made.

Instructions/Footnotes For Table B

 

The numbers of fixtures required for employees are included in the numbers shown in Table B for all building types/uses except Hospital Rooms, Penal Institutions, and Other Institutions.  The entry in Table B entitled "All Facilities for Employee Use" shall be used to determine the minimum number of fixtures required for employees in hospitals, penal/other institutions, and all other buildings/facilities that do not appear in Table B.

 

Questions concerning the minimum numbers of fixtures required for building types not listed in Appendix A, Table B, shall be referred to the Department in writing prior to construction for a decision concerning the minimum numbers (and types) of plumbing fixtures required.

 

Footnotes:

 

1.         The figures shown are the minimum number of fixtures required for the number of persons indicated or any fraction of that number.  Based on the total occupant load determined, the number of fixtures shall be calculated assuming 50 percent of the occupants are male and 50percent are female.  The total male/female occupants shall be calculated first; then the number of fixtures for each (males/females) shall be determined from the appropriate table.

 

2.         Urinals may be substituted for water closets for males, not to exceed half of the required total number of water closets.  Comparable fixtures for females may be substituted for water closets for females, not to exceed half of the required total number of water closets.

 

3.         18 lineal inches of wash sink or 18 inches of a circular basin, when provided with water outlets for space of this kind, shall be considered equivalent to one lavatory.

 

4.         Whenever a drinking fountain is required by this Part, bottled drinking water or a water dispensing faucet (water station) may be substituted for a drinking fountain, provided drinking water is accessible to the public.  When bottled drinking water is provided in lieu of a drinking fountain, the bottled water used must be commercially sealed in accordance with the Illinois Bottled Water Act and with the Illinois Safe Bottled Water Act.

 

5.         The kitchen sink and laundry tray or connection for the washer are not required for the hotel/motel unit.

 

6.         In addition to providing separate hand-washing facilities in the kitchen for employees, all food service establishments shall provide a minimum of one service/utility sink and one three-compartment sink to sanitize dishes and eating utensils; however, a mechanical dishwasher may be substituted for a three-compartment sink to sanitize dishes and utensils. (See 77 Ill. Adm. Code 750.)

 

7.         Bathtubs/showers that are required for employees by OSHA requirements, collective bargaining agreements, etc., shall be provided at the rate of one per 10 employees.

 

8.         Food Service Establishments with no more than 10 combined employees and seats (for patrons) at any one time need not provide public restrooms, provided that the employee restrooms are accessible and made available to the public.

 

9.         Bed and Breakfast facilities with more than five sleeping rooms shall meet the minimum requirements of this Part for Hotel/Motel units.  Bed and Breakfast facilities with five or fewer sleeping rooms, in compliance with the Bed and Breakfast Act, need not provide individual restrooms for each sleeping room.

 

10.         Businesses that sell motor fuel but do not have any employees working as attendants are not required to provide public restrooms.

 

11.         In Day Care Centers providing restroom training facilities for occupants ages three and younger where continuous adult supervision is provided, restrooms are not required to be separated into facilities for males and females, and are allowed to contain multiple lavatories and water closets as required by this Part.  Public restrooms shall be required for everyone over the age of three separate from the restroom training facilities as required by this Part.

 

12.         Drinking water shall be provided in accordance with Section 890.720(f).

 

13.         The total number of bathing facilities shall include one bathtub for males and one bathtub for females or one individual user restroom with a bathtub.
