4. Plan review
requirements for multiple dwellings. See Table 82.20-2
which states "For the purposes of plan submittal, public buildings do not
include zero-lot line row houses where each living unit is served by an
individual water service and an individual building sewer." For
clarification, these individual connections (water and sewer) are to the public
sanitary sewer or public water main, or to a private interceptor main sewer
and/or private water main. The building may be defined as a row house,
apartment or condominium, but the individual plumbing system requirement must
be met. For the interpretation of this section, the private interceptor main
sewer and private water main extends to the most upstream building served. So all buildings are treated identically.
Because of their individual connections each row house would be required to
have one full sized drain and vent stack.

92. When are cleanouts required for sewer offsets? The installation of an 8" or larger sanitary sewer requires additional manholes at every change in direction of 45 degrees or more. The installation of two 1/16 bend fittings with piping between is not considered to be a change in direction of 45 degrees or more. An installation of street fittings to create a fitting are to be considered one fitting. Storm sewers 12 inches or larger in diameter are required to comply with this requirement. However, storm inlets with an inside diameter of at least 36 inches can serve the purpose of a manhole. Private interceptor main sewers 6 inches or larger in diameter are required to include a manhole at every change of direction. This change of direction is not specific to any offset measurement.

93. Is a manhole required for a vertical change of direction? No. The code's intent is to have the manhole and cleanout requirements for sewers and private interceptor main sewers apply to horizontal changes in direction, not changes in elevation. This applies to the requirements in 82.35 where cleanouts, manholes or storm inlets are required for changes in direction of 45 degrees or more and also where the code requires for a manhole where there is a change of direction.

129. Is there anywhere in the plumbing system where a stop and waste-type control valve may be installed underground? There is no definition for a control valve in the code or statute, so the interpretation of where a stop and waste-type control valve may be installed is based on the probability of incidence and the historical precedence of the plumbing trade. One installation of below-ground bleed type devices has been for fire hydrants which are emergency fixtures and have less of a probability of groundwater impact or serving as a drinking water source for the public. Similarly, a large diameter hydrant (2" or greater outlet) that serves a wastewater treatment plant on the protected non-potable distribution piping has the same low probability for serving as a public drinking water source or increasing the risk of contamination near the wastewater treatment plant.

131. Booster Pumps and backflow protection. Booster
pumps are generally hard piped to the water supply and then use a hose at the
outlet end of the pump. ALL booster pumps installed permanently must be
connected to the water distribution system with approved water distribution
materials (see chapter 84.30). Booster pumps must be provided with an
automatic low pressure cut-off switch to protect the booster pump in the case
of loss of supply pressure when the booster pump is serving plumbing fixtures,
appliances or pieces of equipment. All booster pump installations must
take into account the pump’s affect on the plumbing water distribution
system. Following are acceptable backflow protection options for booster
pump installations: Inlet side of booster pump (continuous use) -
RP (ASSE 1013) installed in water supply. Outlet side of booster
pump - > 150 to 350 psig. RP (ASSE 1013) installed in the water
distribution system downstream of the pump. In this case the pump
materials in contact with the water must be water distribution approved
materials. - > 350 psig There are no backflow preventers manufactured
to withstand these pressures at this time.

(c), Wis. Adm. Code (sewerage treatment facilities or marinas, wharves and
docks)?
No. At this time there are no provisions in the code or statutes that would
permit local ordinances that supersede the uniform plumbing code requirements
for containment. Section 145.02 (2) states that "The department shall have
general supervision of all such plumbing and shall after public hearing prescribe,
publish and enforce reasonable standards therefore which shall be uniform and
of statewide concern so far as practicable." The definition of
"practicable" is "capable of being effected, done or executed;
feasible." In several cases the plumbing code has specific allowances for
cities to adopt ordinances or enforce requirements in excess of the plumbing
code. Comm 82.41(3) has no such permission.

159. Do all chemical dispensing systems require to be
listed by an acceptable listing agency as meeting ASSE Standard 1055 or receive
a written product approval from Dept. of Commerce? No. There
are currently three ways to determine if a specific chemical dispensing system
can be installed in
1) It meets ASSE Standard 1055(1)
2) It has received written alternate product approval from the department, or
3) It has received written alternate system approval from the department.
Note (1) ASSE Standard 1055 only applies to those devices classified as
chemical dispensing systems having self-contained means of backflow protection.
Since there are many chemical dispensing systems that do not
have a self-contained means of backflow protection, the department decided to
require that type of chemical dispensing system to receive an alternate
plumbing product approval in accordance with Comm. 84.11 and Comm. Table
82.41-2.
The Department has issued an Alternate Plumbing System Approval regarding
chemical dispensing systems that are not covered by ASSE Standard 1055.
The alternate approval includes the following stipulations
that must be followed.
Stipulation #1 – Chemical dispensing systems that are not in compliant with
ASSE Standard 1055, may be installed when the installation includes an
acceptable cross connection method or assembly in accordance with Comm. 82.41
(3) Table 82.41-1 of the Wisconsin Administrative Code.
Stipulation #2 - The installation of the cross connection method or assembly
must comply with s. Comm. 82.41 (5) of the Wisconsin Administrative Code.
