[Amended 4-11-2006 by L.L. No. 5-2006]
Ordinary repairs to the plumbing system may be made by a master plumber duly licensed in the Town of North Hempstead without application to the Chief Building Inspector. Such repairs, however, shall not be construed to include addition to, alteration, replacement or relocation of any standpipe piping, water distribution piping, house sewer, private sewer or drainage system including leaders, or any soil waste or vent pipe, or any gas distribution system. Such repairs are classified as additions and alterations and shall not be made until application has been made and a permit granted. Where repairs include replacement or installation of fixtures only, without addition or alteration of existing piping, a permit will not be required but written notice of such repairs shall be given to the Chief Building Inspector before the same are commenced, and the work shall be done in accordance with this code and/or any rules and regulations prescribed by the Building Department.
Where repairs or alterations ordered by the Board of Health for sanitary reasons include cases where new vertical and horizontal lines, or soil, waste, vent or leader pipes are proposed to be used or old ones replaced, drawings and descriptions must be filed with and approved by the Chief Building Inspector before same shall be commenced or proceeded with.
Repairs and alterations may comply in all respects with the weight, quality, arrangement and venting of the rest of the work in the building, except when an existing soil waste or vent line has been damaged by fire or other causes to the extent of 50% or more of its entire length; and same must be replaced by new lines installed in accordance with the rules and regulations governing new lines.
No plumbing or drainage or any part thereof, except as stated in § 2-36G, shall be commenced until the plumber who is to do the work shall sign the specifications and made affidavit that he is duly authorized to proceed with the work. Affidavit must give the name and address of the plumber, and such other information as may be required by the Examining Board of Plumbers. It shall be unlawful for any licensed plumber to sign the specifications and act as agent for a plumber who has not obtained a license from the Examining Board of Plumbers as an employing or master plumber. A violation of this rule will be deemed a sufficient reason by the Chief Building Inspector for the cancellation of a license.
One set of specifications will be received for not more than 10 houses, and then only when on adjoining lots and houses are exactly alike.
Written notices must be given to the Chief Building Inspector by the plumber when any work is begun, and at such times as the work is ready for inspection.

All sections or parts of sections of the Multiple Dwelling Law relating to plumbing and drainage of multiple dwellings are to be observed and are hereby made a part of these rules and regulations.
The Chief Building Inspector may require the entire plumbing and drainage system within the building to be tested under a water test by the plumber in the presence of the Chief Building Inspector or such agent as he may appoint for that purpose. All pipes must remain uncovered in every part until they have successfully passed the test. The plumber must securely close all openings, as directed by the Chief Building Inspector. The use of wooden plugs for this purpose is prohibited. The water test will be applied by closing the lower end of the main house drain and filling the pipes to the highest opening above the roof with water. The water test shall include, at one time, the house drain and branches, all vertical and horizontal soil, waste and vent lines and all branches therefrom to a point above the surface of a finished floor and beyond the finished face of walls and partitions. If the drain or any part of the system is to be tested separately, there must be a head of water of at least six feet above all parts of the work so tested, and special provision must be made for including all joints and connections in at least one test.
When it is necessary to use a sump system and sewage lift to receive the discharge from the waste or soil connection of fixtures, the same shall be arranged to be accessible. If discharged with compressed air, it shall be connected to the house drain on the sewer side of all leader or area drain traps and fixture connections, or may be connected to the house drain on the sewer side of the house trap. A separate trap and fresh air inlet must be provided on the inlet side of the sump and a four-inch pipe continued from drain discharging into sump up to and above roof for purposes of ventilation. Relief pipes must be provided on sewage receptacles of sumps. Traps of fixtures connected to sump systems must not be vented to vent lines which are used to ventilate traps of fixtures on gravity system. Sump systems should be entirely separate both as to discharge and venting from rest of plumbing system in buildings.
All garage floor drains shall discharge into dry wells. When necessary to connect to a sewer, an approved oil separator must be used. Oil separators installed in any building where volatile fluids are used must be arranged to be readily accessible, and to receive only volatile fluids. They must not receive the discharge of any water closet, rain leader, yard, court or area drain.
Oil separators must, if discharged by gravity, be connected by a Y-branch fitting to the house drain behind the house trap in such manner that they will not interfere with the house drain and the rest of the plumbing and drainage system. When mechanical force is used to discharge the contents, the connection must be made by a Y-branch fitting on the sewer side of the house trap.
No separate running trap need be provided on the drain entering oil separators, but a separate fresh air inlet and vent line must be provided to keep the system of drainage controlled by the oil separator entirely separate from the rest of plumbing and drainage system.
The size of the fresh air inlet shall be determined by the size of the inlet connection to the oil separator, which shall be considered the same as the term "house drain" for determining the size of all fresh air inlets, which shall conform to the same requirements as regards size and arrangements of terminals for fresh air inlets as called.
Vent lines shall conform in all respects to vent lines for plumbing fixtures as regards size and arrangements.
Relief pipes at least 1 1/2 inches in diameter must be provided. They may be connected to a vent line when installed as a separate system or must be carried independently above the roof.
Every building, except residential buildings of 2 1/2 stories or less and private garages, shall be kept provided with proper metallic gutters and rain leaders for conducting water from all roofs in such manner as shall protect the walls and foundations from injury. In no case shall the water from any rain leader be allowed to flow upon the sidewalk or adjoining property. The water from leaders may be conducted by proper pipes laid below the surface of the sidewalk to the street gutter upon obtaining a waiver pursuant to § 70-202.2D, or may be conducted by reinforced concrete or PVC pipe to a leaching cesspool or appropriately engineered infiltration landscaping via swale or PVC pipe located at least 10 feet from any building. No plumbing fixtures shall be discharged into a stormwater drywell. Leaders in residential zones may be drained to the surface, rain barrels, dry wells or a combination thereof.
[Amended 5-13-2014 by L.L. No. 6-2014]
Inside leaders must be made of cast iron or galvanized wrought iron or steel, with roof connections made gastight and watertight by means of a heavy lead or copper-drawn tubing wiped to a brass ferrule or nipple caulked or screwed into the pipe.
Outside leaders may be made of sheet metal.
Rainwater leaders must not be used as soil, waste or vent pipes, nor shall any such pipe be used as a leader.
Where inside leaders are used, Y-branch and bend to the outside wall of the building, 12 inches above grade, must be installed to act as an overflow in case of stoppage.
Hereafter the gas piping and fixtures in all new buildings and all alterations and extensions made to the gas piping or fixtures in old buildings must be done in accordance with the provisions of the Building Code. For additional requirements of public buildings, theaters and places of assemblage, see the Building Code.
Before the construction or alteration of any gas piping in any building or part of any building, a permit must be obtained from the Chief Building Inspector.
