RE: Problems with venting of your plumbing fixtures. 13 b 3 rcl A �e
Dear Resident:
PETER E. HAHN
DIRECTOR
The City's sewer cleaning records show that the home at this address is
experiencing problems with the venting of some of your plumbing fixtures
when the City crew is conducting cleaning operations of the City sewer line
in front of this address.
The City's cleaning operation is essential for both you and your
neighbors. It cleans debris in lines to prevent plugs, prevents corrosion
and potential future collapse, and achieves a better flow characteristic in
the public sewer lines. We need to do this often -- perhaps even 3 times a
year -- in some critical areas. The City's cleaning operation typically
involves the utilization of a high pressure water jet.
The problem which occurs at the home is the result of a high pressure surge
through your internal plumbing system. A properly constructed plumbing
system is designed to easily vent this additional pressure without any
visible impact at your residence. An undersized venting pipe (or not
having enough vents) cannot handle the pressure surge, and the only release
that's available is then through your toilet (or another fixture). The
Uniform Plumbing Code typically requires a 2" vent, and further requires a
separate vent for each plumbing fixture which is connected to the sewer (a
toilet, a sink, a shower). Your home clearly does not have an adequate
venting system (you either have a 1-1/4" vent, or not enough of them), and
you therefore may continue to experience the pressure surges.
The City does not have a choice as far as discharging its responsibility in
cleaning the public sewer line. It is therefore up to you to take
corrective measures as to how to properly vent your own plumbing system.
The City has come up with two options that will remedy your problem:
Option 1: Upgrade stack vents for toilets and other fixtures which
are experiencing problems to required sizes.

Option 2: Install a clean -out outside of house per attached
specifications. Enclose box so it can vent properly when
excess pressure is put on house lines. This option would be
the cheapest and simplest way of correcting this problem.
At the same time, it would allow access to sanitary sewer
lines if stoppage should occur. This vent clean -out would
allow a place for backup in lines to go before entering your
house and causing costly damage.
The City would appreciate your expeditious cooperation in this matter. The
City must continue proper maintenance of its sewer lines, but we obviously
do not wish to see continued problems occurring on your property because of
poorly designed vents. It is your responsibility to correct these
deficiencies.
We cannot keep notifying you each time we come out to clean the line. It's
up to you to have a plumbing system that conforms to code. Option 2 is a
relatively simple one to construct.
Should you have any questions on these options, please call Everett Akau,
Scott Highland or myself at 771-3202, extension 317 or 318.
Sincerely,
Ron
