Ron,
I think the water districts in our area all use one inch taps off the main
regardless. I personally haven't been on any that were changed. If it others
in the office have had this experience I've missed it. On the technical side,
the 5/8 x 3/4 and 1 x 1 meter use the same main tap. Cha
I think Joe had you in the right spot: nfpa #13 8.15.1.5. ('07 ed.)... since
your walkway is only 3 ft wide the way I see it you would only have one row
of sprinklers spaced at the appropriate light hazard spacing.

In our fee ordinance the fire protection permit fees are determined by the
work and not its value. The permit and plan review fees are calculated based
on the system and its components, i.e. number of dry valves, sprinklers,
hose outlets, fire pump, etc. etc. By doing this the permit fee is unifo

These are all valid points, but the issue I see is that this "contract"
paperwork becomes part of the submitted plans which in turns becomes
public records. The majority of the jurisdictions we deal with base the
permit and inspection cost on sprinkler head counts or device counts for
FA systems. W
Hello Craig,
Emergency Pager went off at 6pm one Friday. It turned out to be a customer
where we had replaced the jockey pump the day before. His electrician had
been out that morning and wired up the new jockey pump and life was good

We've been doing that for years. Ever since they found out that some
contractors were "Low Balling" those numbers to make their permit fee's
lower. The One problem I have with it is, that your paying for a permit that

Mike,
Have you asked them to provide a code reference? An AHJ can not legally come up
with their own "Because I Said So" code. I suggest all contractors to request a
code reference when there is a question on scope of authority. If the AHJ can't
provide a reference, then what right will they hav
I'm almost certain that they can't. Valuation is supposed to be based on
tabled values or an owners declaration. Earlier versions of the CBC included
valuation charts for purposes of establishing permit and plan check fees.
Check with CALBO, the California Building Officials web site at www
In a certain southern California city a sprinkler contractor fills out an
application to install a system. On that application the job valuation must be
included. The valuation is used by the city to determine the fees for that
particular job. The plans examiner is now requiring the contractors
But make sure that electrical components (motors especially) are U.L.
labeled. Some AHJ's do look for that label. Some of the cheap overseas
knock-off products aren't UL tested or labeled. It would be real sad to
have a fire in a pump room/house started by one of the fire protection
system compo
Agree - Jockey pumps or Pressure maintenance pumps as the standard calls
them, do not have to be listed.
Hope this helps,

this section is addressing the use of other types of FIRE pumps. The
standard does not identify types of Jockey pumps that you can deviate
from. They are not required to be listed. This will be better
clarified in the next edition (based on the outcome of the recent ROP)

We recenly went through this for a USDA application in a clean room for meat
cutting, where hot water and steam are used to clean up every day, causing a
corrosive environment to exposed sprinkler heads.
We looked, and no such animal exists. The closest you can get is an "MRI"
room head that
When I look at NFPA #20 section 5.1.2.1 it looks like a jockey pump must
be listed. I had it in my mind that it didn't. My mind vs the standard?
...probably not a fair contest but just wanted to check and see if I am
missing something. Thanks.

Does anyone know of a concealed sprinkler and plate with a corrosion
resistant finish? I have a spec requiring this sprinkler over a pool.

I have a project where the sprinkler vendor has covered an attic space
using 130 sqft spacing. The attic is wood trusses on 24" centers with a
6/12 pitch. I think his installation should be based on the unoccupied
attics having combustible wood truss construction with members less than
3 ft on c
Bruce,
All valid concerns. As a sounding post one of the many benefits of this
forum. While some subjects may get beat to death the discussions are healthy
and allow everyone to weigh in. In a sense its no different then attending a
