All potable water supply to all fire water storage tanks shall be piped to the highest part of the tank with an approved air gap and or reduced pressure principle backflow prevention assembly per AFI 32-1067

Isolate any system over 20 heads to permit pressurizing new installation to 200 psi while leaving existing system at working pressure.

Fire water storage tank fill valves that use electrical means to operate a control valve will use separate sensors from the high and low water level alarms to operate the level control valve within the 1 foot allowed between the high and low level alarms IAW NFPA 22 and 72

44 Under floor detection shall be accomplished through an Air Aspirating System.

Please provide a box and a copy of all fire suppression O&M's and asbuilt drawings in riser room mounted to a wall. This does not need to be an additional copy to the required copies turned in at the end of the contract.

When pipe thread sealant is used, use non petroleum based product. We have found oil residuals on heads from the oil separating from the base of the thread sealant.

CPVC is prohibited for use in all sprinkler systems. For transitions into secure vaults use grounding per SCIF UFC 4-010-05, paragraph 3-5.8.2 for sprinkler pipe penetrations. Grounding

All check valves over 2" shall have a cover plate for maintenance without removing the check valve assembly from the piping system

Instead of automatic air relief valves that will leak Install a minimum one inch diameter auxiliary drain connected to the fire suppression system at a high point that allows air to be purged from the system piped to the outside of the building for every 3,000 square feet of wet fire suppression system protection. Example a building with 30,000 square foot protected by wet fire suppression systems shall have 10 auxiliary drains connected to the fire suppression sytem at a high point which facilitates the purging of air remotely spaced from each other and the alarm valve with easily accessible without the use of a ladder full port ball valves piped to the outside. All wet fire suppression systems inclueding shotgun systems shall have a minimum of one inspectors test and one auxiliary drain remotely located from the riser and each other, piped to the outside with an easily accessible without the use of a ladder, test and drain valve. Another good option for purging air in larger systems is connecting all the branch lines together at the high point and running it to the outside with a readily accessible full port ball valve or test and drain the same size as the piping. The larger the system, the larger diameter the piping will need to be connecting all the branch lines and running to the outside, in order to purge enough air.

On Foam systems - Please install 1" diameter schedule 40 steel piping for a solution pressure point at the inlet to the most remote foam generator. Hard pipe it so that it completely drains with no water trapping points whatsoever to a readily accessible location outside of the foam hazard and high enough off the floor to put a 55 gallon drum under it to facilitate flushing and draining the line. Please install a valve at the tap and one for the pressure gauge at the outlet . Please provide a metal placard with the distance (height) to the inlet of the generator, install it at the base to assist with calculations to figure the pressure at the most remote generator during a foam flow.

55 City water bypass loops shall not be utilized on fire pumps supplied by a non elevated fire water tank.

56 All wet fire suppression systems shall be installed in a heated and insulated space.

All underground fire suppression piping including fire pump systems shall be welded stainless steel or piping that requires butt fusion methods to join the pipe. Service risers transitioning from underground shall be welded stainless steel from an accessible location outside the building. All mechanical joints shall be tightened with a calibrated torque wrench to the manufacturers specifications by continuously tightening every bolt, working around the pipe until the torque wrench clicks for every single bolt without the nut spinning. Most underground leaks are caused by failure to tighten joints thoroughly. No loss of pressure or visible leaks allowed on underground fire pump or fire suppression systems. A small leak will grow over time because the stream will eat away any material it is leaking past. Pressure loss causes frequent jockey/pressure maintenance pump cycling and jockey pump controller and pump failures. Underground leaks here do not surface because of the sand, until the leakage flow rate accedes the pressure maintenance pump capacity which causes the fire pumps to run continuously. Fire pumps running continuously will burn up leaving all facilities unprotected.

All fire suppression systems piping shall be installed with a protective coating that inhibits corrosion applied to the inside of the pipe. One example would be Eddy Guard 2 from Bull Moose Tube. These coatings only last for a period of time depending on the company and it is still critical to install all piping so that it drains completely with no water trapping points whatsoever.

Before connecting any potable drinking water piping to any fire suppression system Schedule the 796 backflow prevention program manager and the fire suppression subject matter expert to be present.

AFI 32-1067 AWWA manual M-14 requires with out exception all backflow prevention assemblies to be tested by a cirtified backflow prevention tester with a current state cirtification for backflow testing immediately after installation, when put in to survice, when taken out of survice, when cleaned or repaired, when maintenance or repair is done upstream of the backflow prevention assembly and annually.

During installation, maintenance or repair upstream of the backflow prevention assembly keep the inlet shut off valve closed and flush the piping thoroughly upstream before opening the inlet valve. Thoroughly flush the upstream piping of the backflow prevention assembly and the fire suppression system before connecting the piping.

Concrete splash blocks large enough to prevent ground erosion shall be placed to intercept discharge from all inspectors tests, axillary drains and main drain outlets .

Read, study and actually know the project specifications, NFPA, UFC 3-600-01, AFI 32-1067, AWWA Manual M-14, and for Hangars UFC 4-211-01, check the specifications for any Air Force ETLs and all other codes.

Readily accessible means capable of being reached quickly for operation, renewal, or inspection, without requir‐ ing those to whom ready access is req‐ uisite to climb over or remove obsta‐ cles or to resort to portable ladders, chairs, etc.
