Use Fire Pump at 145% to Avoid 8" Underground?

2/21/2023

15 Comments

 
I have question regarding fire pump capacity.

In my situation the water department is requiring a city tap size to be 2 pipe sizes larger than the fire protection backflow preventer.

In my project, I was using a 4" backflow and 400 gpm fire pump so my underground/city tap would be required to be at least 6 inches.

The AHJ is requiring me to increase the area size in one of my remote areas. So, my sprinkler demand now becomes 582 gpm. To avoid having to use a 500gpm fire pump (with a minimum suction size of 6-inch) and increase the underground to 8-inch, could I still use the 400 gpm fire pump to supply the 582 gpm demand?

This comes out to about 145% of the pumps rated capacity.

I have never come close to the 150% mark before and just want to see what others think. If the underground size wasn't required to be 2 inches larger I wouldn't even think about it and go with the 500 gpm pump.

Thanks in advance.

Is Use of C900 for Fire Service Entry Acceptable?

2/16/2023

16 Comments

 
We have a building that is constructed. It has a very deep footing.

The contractor originally submitted an Ames In-Building Riser, but it's too deep for the in-building riser in the building's (essentially) existing condition.

They proposed using C900 to come under the footing, without a sleeve, going below the 12" footing and then stubbing up into the riser room without thrust blocks.

We have concerns about restraint and a change of direction underneath the foundation.

NFPA 13 applies and C900 is a permitted material, which is what the contractor has suggested makes it acceptable.

Is routing C900 under a building footing, changing direction, and then stubbing into the building acceptable?

What Mandates Ductile Iron Until the Backflow?

12/20/2022

16 Comments

 
We are doing the install for a new building. The fire sprinkler underground comes in the building and they are requiring ductile pipe be used inside the building up to the backflow preventer.

Can anyone cite literature for this?

I know NFPA does not require the use of back-flow prevention, but am interested in the code basis for the pipe type until the backflow preventer.

Thanks in advance.

Maximum Allowable Pressure for Fire Hydrant?

8/1/2022

9 Comments

 
We have a proposed fire hydrant in our county that will have pressures ranging from 210 psi to 250 psi according to the engineer designing the underground line.

My Chief and I are looking into this in regards to NFPA standards/applicable code, and are concerned that the high pressure could injure firefighters or damage equipment.

Is there a maximum permitted pressure that a hydrant can be, per code?

Thanks in advance.

I have a job where the plans have a detail of the underground fire service entry into the building that shows us bolting to friction clamps. I've always used the 90-degree I bolts on the flange to shields.

Looking for some detail on this - are there other methods I should be considering? Is this acceptable?

Where is C900 Allowed for Underground Service?

3/4/2022

5 Comments

 
When is C900 PVC allowed below buildings before the transition to metallic pipe for spigot stub up?

I often see municipal rules to keep non-metallic pipe no closer than five feet from the building foundation. 

Where does this requirement come from?

I have no problem with this practice but would like some code justification to discuss this with contractors.

Thanks in advance.

Pool for High-Rise Secondary Water Supply?

12/28/2021

6 Comments

 
Can a commercial pool be used as the required secondary water supply to a high-rise sprinkler system?

The 2019 IBC/CBC Section 403.3.3 requires an automatic secondary water supply in certain seismic design categories. This is typically met by installing a dedicated tank that meets the minimum demand for 30 minutes.

I have a developer asking if they can run a feed line to their 100k +/- gallon commercial pool so it can serve this purpose.

Outside of the engineering challenges and value engineering their team must address, I'm wondering if this arrangement is even allowed. I cannot find anything in IBC/CBC, NFPA 24, NFPA 13, etc. that wouldn't allow this. Any help is appreciated.

How to Start All Municipal Pumps with Flow Test?

12/20/2021

18 Comments

 
We have an oil storage warehouse project requiring a ceiling density of 0.60 gpm/sqft over 3,000 sqft.

This is basically 30 sprinklers using 1,900 gpm (sprinklers), and 500 gpm (for hoses).

The municipal system is set up with three pumps that run sequentially based on residual system pressure. Each pump is larger than the last. We require Pump 3 to be in operation in order to get the required flow and pressure.

We have conducted a flow test flowing two hydrants, and have not been able to kick Pump 3 into action.

Assuming a K16.8 sprinkler has a 3/4" orifice, 30 heads would only equal a 4" diameter opening. If we can't activate the appropriate pump by opening multiple hydrants, how will we be able to achieve the required flow during a fire?

Has anyone encountered a supply system like this before?

I know that a tank and pump is a solution, but I'm looking for other options. Thanks.

Tap Fire Supply for Water Source Heat Pump?

9/1/2021

8 Comments

 
We are working on a project where the site engineer is asking if tapping into the underground fire line is acceptable to supply a water cooling line to a water source heat pump unit with a 3-inch line.

I'm having trouble finding where it is not acceptable and thought I'd reach out to the knowledgeable members here.

This site has a combination potable/fire line as shown in the picture below.

Should we require them to tie into the 8-inch tap from the potable water line upstream of the fire protection vault (blue line in the drawing)?

Or is it OK that they tap into the fire supply line downstream of the fire protection vault (red line below)?

Is Blazemaster Permitted Underground?

8/31/2021

8 Comments

 
Working on a new resort hotel and it is necessary to have buried pipe before and after a sprinkler control valve.

Is it allowable by code to substitute C900 PVC pipe with Tyco Blazemaster pipe?

According to the installation guide of Tyco Blazemaster it could be installed underground.

If not, which material can be installed instead of C900 because 4-inch is the smallest size for this pipe?

Why Pressure Loss Between Street and Backflow?

1/8/2021

18 Comments

 
We are inspecting an existing fire sprinkler building for an upgrade to an Extra Large Orifice (ELO) system.

We performed a hydrant flow test and noticed a 14 psi static loss between the hydrant, 185-ft of 8-inch ductile, 2 elbows and 8 feet of elevation rise to the supply side of the RPZ backflow preventer.  We recorded 73 psi at hydrant and 59 psi at the number 1 test cock on the RPZ while static.

I spoke with the water authority and they confirmed no meter or check valve on the 8" fire line; it is straight into the valve room plus 2 elbows. The building is 20 years old and the pump test provided 120% of rated capacity.

Any idea how the static pressure inside the building is 14 psi less?

Do Other Consultants Review Site Utility Plans?

12/30/2020

11 Comments

 
I've been seven years in the chair, and the most thankless job I encounter on every project is - reviewing the site utility plan and picking it apart.

I've now made my own rule that I will only point the civil engineer's mistakes once, early in the project, and when it comes time to stack the riser, pressure test, etc, all I can say is "I pointed that out to you on Aug 11 2020 email."

Am I going about this the wrong way? SHould I even be investing energy into correcting the engineer with the stamp?

Recent example is a two story building with concrete tees. We're adding third and fourth floors from new structural members. The underground man took the site utility and started digging. Check valve was exposed above ground (supposed to be in pit) and the FDC was connected to the underground on the system side of the backflow preventer. Now he has to dig it up, cap the tee after the backflow preventer, and run it around and inside the building. The job requires a small pump (CL1 manual wet standpipe), and the underground man wasn't happy. All I was doing was point out wrong installations before it was too late.

I'm always left thinking, "this isn't even in my scope of work, but it affects everything downstream."

Hydrostatic Criteria for Remote FDC in NFPA 25?

10/22/2020

3 Comments

 
We have an account that failed the five year FDC hydrostatic test. The Fire Department Connection is a remote, freestanding FDC. The Fire Marshal is claiming that there is no leakage, however, will not give a pass or fail. 

NFPA 25 (2017) and others reference hydrostatic tests.

6.3.2.1  hydrostatic test 200 psi for 2 hrs or at 50 psi in excess of the maximum pressure where maximum pressure is in excess of 150 psi every five years. (manual standpipe systems and semi-automatic dry standpipe systems, including piping in the FDC)

Annex  6.3.2.1* that mentions a minimum leakage existing under test pressure.

Section 13.8.5 FDC five year hydrostatic testing shall be tested at 150 psi for 2 hrs. There is no mention of minimal leakage allowed.


What is this allowable leakage?

NFPA 24 (2010) Private Fire Mains & Their Appurtenances Section 10.10.2.2.1 requires 200 psi or 50 psi in excess of the system working pressure whichever is greater and maintain that pressure at +/-5 psi for 2 hrs.

Is that my allowable leakage, so that if we lose less than 5 psi or gain no more than 5 psi for 2-hours, that we pass? Wasn't sure if the existing 5-year hydrostatic for underground has leakage that is measured differently from an inside hydrostatic test.

How to Verify Flow for Underground Flush Test?

7/31/2020

9 Comments

 
Many sprinkler systems in our area (I'm a fire marshal) have aboveground pipe installed by a fire sprinkler installer and the underground installed by an underground pipe contractor. NFPA 24 requires a minimum flow rate from underground pipe in order to remove rock and debris from the underground pipe.

Many of the underground contractors simply open up the pipe and wait until there's consistent clear water and/or stop hearing the rocks ping around. There's no measurements taken for the underground flushing and when I ask for them to verify the flow rate I get blank stares.

Is there a way to tell just by static pressure in the area if opening up the pipe flange is enough flow to satisfy the underground flushing? Or is there a measurement I should be seeing to verify the flow rate? 

Thanks in advance.

Why Does a Hydrant Need a Control Valve?

7/10/2020

9 Comments

 
NFPA 24, Section 7.1.1.2 (2016 Edition), states that control valve shall be installed in each hydrant connection.

What is the purpose of this control valve, other than facilitating maintenance?

Would this be considered a "control valve" per NFPA 24 3.3.3, and does this have to be a post-indicating type valve?
Picture
​Common hydrant arrangement for illustration purposes.
Based on my limited understanding, this control valve is just a post-indicator valve/isolation valve which is for shutoff when there is an impairment downstream. I'm trying to get a better understanding of its purpose. Thanks in advance.

How to Avoid Water Hammer in Sprinkler Pipe?

6/11/2020

5 Comments

 
Please can someone give some information regarding the filling speed of a empty pipeline to a sprinkler line?

In my case there was water hammer in a 6” line, The 16” firewater line was under 175 psi pressure and the opening time was 9 seconds.

Is 3 feet per second more realistic? Or is there a NFPA standard that addresses this? Thanks in advance for your support!

PVC Allowed for Remote Underground FDC Feed?

5/15/2020

9 Comments

 
Have a project which has a remote fire department connection outside of the main building. The fire department connection has its own dedicated feed that goes from the remote FDC, underground, up into the building, where it connects to the fire sprinkler riser downstream of the backflow preventer.

The check valve for this line is required to be inside the building, so the main between the FDC and check valve in the building is intended to be dry.

NFPA 24 (if that applies) allows PVC for underground water service in its table of permitted pipe types.

NFPA 13 specifically states that galvanized steel is permitted to be used between the FDC and the check valve serving the FDC. I can't see where NFPA 13 would mandate pipe types for this arrangement.

Is this underground FDC feed allowed to be PVC?

Required Pressure & Flow Through A Hydrant?

5/6/2020

14 Comments

 
I haven't had any experience doing site calculations before, but I'm curious how it works from a practical standpoint. Fire Flow is required by the International Fire Code here locally, and there's guidance (albeit not formally adopted) in Appendix B of the IFC for a total demand. Additionally, there's hydrant spacing requirements for any particular building, and guidance on how far the hydrants can be from a building.

In order to determine how the hydrants are fed (dead-end vs. looped and size of pipe), are there specific flow and pressure amounts that each hydrant has to be calculated at?

Is it similar to a standpipe calculations where each hydrant has to have a specific flow?

I'm not performing the design work myself, but I'm just curious how that is typically done and pipe size determined.

Any Limits on Fire Service Entry Due to Seismic?

3/25/2020

1 Comment

 
I have a project that is Seismic Design Category D. I'm researching and I thought there were requirements that stemmed from the Northridge Earthquake in 1994 related to the limiting the height/length of the sprinkler service entry.

Is there a 5-foot limit from the underground to the riser for seismic projects?
