(b) The traps of a battery of water closets, pedestal and stall urinals, and bed pan washers may have, instead of separate vent pipes, a vent pipe connected to the common waste or soil pipe just before the branch from the fixture most remote from the waste or soil stack and between the first fixture and the soil or waste stack. If such a battery has more
-70-
than six fixtures, there shall be a similar vent pipe connection before the branch from every sixth fixture, and in no case shall there be more than five fixtures between the vents. Vents shall not be less than four inches in size. This type of venting may be used only when the vertical distance between the water level of the trap and the top of the common waste or soil pipe is not more than twenty-four inches, and where the developed length of the branch waste or soil pipe is not more than three feet six inches between the center line of the common waste or soil pipe and the water level of the trap. Water closets and pedestal urinals shall be considered one type. No other fixtures shall enter the battery system. The inspector shall prepare explanatory sketches showing the method of construction described in this section.
(c) Two or more air pipes may be connected together but in all cases such connections shall be made above the fixtures they serve.
(d) Floor Drains-Single floor drains shall be separately vented unless otherwise noted. Groups of two or more floor drains discharging through separate branch waste pipes not more than fifteen feet long into four-inch or larger main waste pipe serving floor drains only, may be vented on the outlet side of the end floor drain, by means of an extension of the main waste pipe undiminished in size as a vent pipe.
(e) All vents shall be continuous unless in the opinion of the inspector it is not practical; in such cases where vent pipes connect to a horizontal soil or waste pipe, the vent shall be taken off above the center line of the soil pipe and the vent pipe shall rise vertically, or at an angle not more than 45 deg. to the vertical.
(f) All vent pipes shall be so constructed as not to allow the formation of a trap nor their use as waste pipes, with the following exception: (Wet Vent) The waste pipe for a lava- tory in a bathroom may serve as a vent for a bathtub or shower provided that none of the main waste piping is less than 2-in. size.
(g) No vent pipe shall connect with any other vent pipe until it has attained the height of the top of the fixtures whose trap it ventilates.
(h) Location of Vent Terminals-No vent terminal from a sanitary drainage system shall be directly beneath any door,
-71-
window, or other ventilating opening of the same or an adja- cent building, nor shall any such vent terminal be within 12 ft. horizontally of such an opening unless it is at least 1 ft. above the top of such opening. Where the roof is used for any purpose other than weather protection, the extension shall be run at least 7 ft. above the roof.
ARTICLE 10
Water Closets and Toilet Room Requirements:
(a) In all tenements or blocks there shall be at least one water closet for each tenement. In hotels and lodging houses, there must be one water closet on each floor, and where there are more than twelve persons on any floor, there must be an additional water closet on that floor for every twelve addi- tional persons or fraction thereof.
(b) Plumbing and toilet room construction in industrial establishments, restaurants and places of public assembly, in addition to the provisions of this code, must be in accordance with the rules and regulations for toilets by the Mass. Dept. of Labor and Industries. Toilet seats in such establishments shall be open front type.
(c) In all public establishments the floor of every water closet compartment or toilet hereafter installed, and the side walls to a height of nine inches, shall be constructed of material impervious to moisture, and which has a smooth surface. Where urinals are installed, the floors in front for a distance of at least twenty-four inches shall slope to the drain.
ARTICLE 11
Ventilation:
(a) Except in those cases where the rules and regula- tions of the Department of Public Safety require more, the following is the minimum amount of ventilation permitted in compartments in which water closets or urinals are situated:
(b) No water closet shall be placed in an apartment that has not a direct opening of at least three square feet to the external air approved by the inspector.
(c) Every toilet room containing a water closet or urinal which is located so that no window or skylight can be installed directly to the outside air shall be provided with a galvanized iron or copper duct which shall connect such toilet room with
-72-
the outside air. Such duct connections shall terminate inside the toilet room with a register or grille which shall have a free area of the full duct size and shall terminate at the outside air with a weather-proof louver and insect screen.
The minimum size of such ducts shall be equal in area to 35 square inches.
The area shall be increased to allow twenty-eight square inches of free area for each additional water closet and 8 square inches of air for each additional urinal.
ARTICLE 12

OLD HIGH SCHOOL BUILDING REPORT OF THE PLANNING BOARD
The Planning Board reports in accordance with the vote of the Town at the special Town meeting in September, 1951, viz .:
"That the Town raise and appropriate or transfer from available funds the sum of $500, to be expended by the Planning Board to complete their studies with regard to the Old High School building on Lincoln Street, as directed by vote of the Town."
Present Status of Building. The building is of large capacity and structurally sound. It has not been too well maintained, as leaks have damaged walls and floors. There are eight heaters, some of which cannot be operated; and the rest are of little value. The building now houses a few activ- ities, such as Welfare, Old Age Assistance, Sealer of Weights and Measures, etc. The bulk of the space is either unoccupied or used for storage.
It seems clear that such a building should be put to a better use.
School Use. The first question was as to whether this building should be held available for possible future school use. The School Committee tells us that they regard such a need as doubtful and that it should not be taken into account. We agree with that conclusion.
Other Use. As we see it, the Town has a great need for better housing for many Town activities and for many Town records. At the same time, the Town owns this building of which proper use is not being made. Therefore the obvious thing to do was to study its usefulness for the housing of Town activities. Fortunately, it seems to work out both adequately and economically.
Town Offices. The Planning Board has had the services and help of Whitman & Howard, Engineers (the consultant on the Plymouth Compact), and of Mr. Walter M. Gaffney (architect on the Manomet school now being built). Plans have been prepared which are on exhibition and which pro- vide adequate and proper accommodations for all Town departments except Fire, Police and Highway Departments, now adequately housed elsewhere.
-78-
These plans have been examined by the Selectmen, who are unanimously in favor of their execution.
Cost. The estimated cost of converting the Old High School building into a thoroughly good Town Office Building is $215,000. There will result a building which would cost about $450,000 to build. To adopt this plan will provide a good centralized Town Office Building, making use of a presently existing Town-owned property, and at a reasonable cost.
Plymouth Compact. We realize that the Plymouth Com- pact proposed a new building for Town offices in the area between Town Square and High Street. Our first approach to what should be done with the Old High School building was to see if it could not be converted, at low cost, to an office building which would serve temporarily until the Compact plan could be realized. But the cost of such a conversion for temporary use, the large cost of the building the Compact envisaged, and the fact that we have in the Old High School a structurally sound building of substantial value, and well located, led us to the conclusion that it should be remodeled for permanent Town Office use.
We recommend that the Town act favorably on this proposal.
