Fire Sprinkler Systems

Does anyone have the 2002 edition of NFPA 13 regarding the installation of sprinkler systems? If so, I’m trying to find out if an installation in a single family home is correct.


This ranch home is located in Maine where the winters are COLD!! The sprinkler system pipes are located in the attic space, exposed over the insulation in the ceiling. The pipes are cast iron and I am concerned that they will freeze during winter months and possibly burst.

Does anyone have any experience with sprinkler systems?

Robert,


From the NACHI SOP, please note item O.

II. The inspector is not required to:

A. Inspect or operate screens, storm windows, shutters, awnings, fences, outbuildings, or exterior accent lighting.
B. Inspect items, including window and door flashings, which are not visible or readily accessible from the ground.
C. Inspect geological, geotechnical, or hydrological conditions.
D. Inspect recreational facilities.
E. Inspect seawalls, break-walls and docks.
F. Inspect erosion control and earth stabilization measures.
G. Inspect for safety type glass.
H. Inspect underground utilities.
I. Inspect underground items.
J. Inspect wells or springs.
K. Inspect solar systems.
L. Inspect swimming pools or spas.
M. Inspect septic systems or cesspools.
N. Inspect playground equipment.
O. Inspect sprinkler systems.
P. Inspect drain fields or drywells.
Q. Determine the integrity of the thermal window seals or damaged glass.

As HI's we are providing generalist inspections and recommendations. Delving into fire suppression systems requires a specialist. Having said that, I do have a great deal of experience inspecting and testing the type of system that you describe. If the installed system is not an anti-freeze or Dry type which is ok to be exposed in the attic, the pipes should not be exposed due to the potential of freezing and breaking.

As a home inspector, I would simply note the presence of the system and exposed pipes in my report and refer the buyer to the installation contractor (Most systems have a data plate with contact info on them at the riser) for proper maintenance of the system.

Hope this helps,

Best regards,

Russell,


Yes you are absolutely correct regarding the SOP. I should have prefaced my question. I'm doing it as a favor (obtaining more information) and its not included in my report other than they should seek expert assistance to determine if the installation is ok.

Thanks for the info. Its as I suspected in any event.

Bob,


Is it a wet (water in pipes) or a dry (air in pipes) system.

Many buildings up here are "dry" with water only to the control valve in a heated location. Compressed air (usually to 40 psi) is in the pipes to hold the water back. When a head breaks, releases air then water.

Any thing happening October 22nd?

Hey Dana!


I don’t know what kind of system it is except that I did find a small leak coming from one of the joints in the attic space so I presume its wet!


He’ll have to figure that one out I guess when the installer comes to take a look.


Nothing for the 22nd as yet but I'll keep you posted. It may be re-scheduled for later in the month.

Bob,


It also could have anti-freeze in the system, although you would see an anti-backflow devise at the control point.

If it is a wet system without anti-freeze, "Hello Mr. Watervac" this winter.
