It might be just the sprinkler cover or it could be the sprinkler head . Chances are its the cover . Try unscrewing the cover to see whats going on behind . If after the cover is off and you dont see the sprinkler head sticking out of ceiling then simply screw the cover back in , sometimes the cover comes off due to vibrations in the floor / building . It could also be that the sprinkler head is too far inside the ceiling due to bad installation and the cover doesnt reach the sprinkler to be able to screw back inside . So it depends on what you find after removing the cover . Simply unscrew counter clockwise and remove the cover .

Thanks your help. The cover is on tightly. Its the metal spiral that is loose. How is that fastened?

Your Welcome

The manufacturers instructions that come with the Mech T’s say Do Not Lube so you would need to wipe clean the pipe . The heavier Mechanical T’s get lubed . Either way you need to wipe clean the hole . I prefer not to use the cutting fluid but if you want you can use it . I use a pilot clamp and the lube and shavings would just make a mess of the clamp . Personally I don’t think the lubricant is worth the effort .

Any particular type of hole saw you prefer? Bi Metal or Carbide Tipped? Any brand choice? I'm not using any cutting fluid either. Do you do anything extra to cool the hole saw? Also high speed and low torque or low speed high torque? I'm using a cordless 18v Milwaukee brushless

@papasmurf6058 I use Milwaukee drill. High speed . High torque . Faster and stronger the better on small size holes . I don’t want the drill to stop ! Bi Metal works good . No preference on hole saws I use whatever hole saw my company buys or suppliers stock .

Okay thank you for the insights. I'll use setting 2 for high speed tomorrow since I'm drilling 1.25" holes for grooved mech tee 🙏

No , you will need to remove the head and add an extension to the head itself .Or change the head to a Globe 1 inch drop head .

@@SprinklerFitting A black extension nipple make it way longer 😥

You said it was an inch deep inside the ceiling , if it’s the opposite then you must cut a hole in the ceiling and cut the pipe .

@@SprinklerFitting It would be a big project if I have to cut a little open the ceiling to be able to insert the extension inside also. Thought I think it would work because there is free room above the elbow and a little play that could accommodate the cap. Also good question, in the worst case scenario it couldn't be applied any adhesive to the backside of the cover at the edge for it to stay flush with the ceiling?

Just open the drain valve a little until the pressure goes down .

@@SprinklerFittingI almost got my head blown off taking off a coupling after another guy said the pressure was released

@dontoday I know what you mean ! I always verify the gauge and position of valves before I undo anything .

Sorry didn’t have time draw cartoons and stick figures.

I'm a fitter for over 25 years and that's why my comment, you just confused people...!!!!

I always ream . If you dont then an un- reamed pipe creates pressure loss .

Many decades ago a company didnt have a reamer attached to the carriage , when the city inspector noticed this they wouldnt pass the inspection until all the threaded piping was removed and replaced .

Shouldn't ram the reamer blades into pipe often a burr is left in the cut opening curled sitting sideways the curl is usually broke off so it's a hard uneven part for the reamer blades to hit and chip leaving an unequal dissatisfying ream giving the pipe lip an opportunity to create failure and injury... what I learned...

It will take a while , most important is to lift properly , bend at the knees , dont rotate body with pipe on shoulder as you will get lower back injury , need to turn with you feet keeping body straight . If it heavy get help , use mechanical means when possible , pipe cart ,pipe cricket etc . Dont be a hero as your boss wont pay your bills if you get hurt . Take your time .

They come with new sprinklers . Not sure if you can order them . Just use tin foil , easy to remove .

That was my attempt to affect the algorithm

se llaman escudo de placa oculto, depende de la marca que haya instalado, si quita uno del siguiente adyacente tendrá una etiqueta con su nombre en el interior con el número de modelo y la clasificación de temperatura. serán comerciales o residenciales, las marcas más populares son Tyco, Victaulic o Globe. necesitará encontrar un proveedor de rociadores contra incendios en su área; en Canadá utilizamos Wolesely, Emco, National Fire o Flocor.

Actuator

They are metal , mostly tin i believe .

Just need to have a good eye .There will be a wall built later .

You could set a square off the back wall and then subtract 1/2 the outside diameter of the pipe .

Its called a Pilot Clamp . Sprinkler wholesale might sell them . You can also google the name . National Fire Pilot Clamp . Comes in a yellow box .

@@SprinklerFitting thank you so much

All the heads are exposed to the elements , sunlight and there is no heat collection possible .

Ill put plugs after i finish testing and tripping the system . This is a new building with six parkade levels . I put street 90's on the ends so i dont dirty the walls when i drain the system , i do know what you mean though .....

Glad you think so!

@@SprinklerFitting I'm installing one it's a 6500 unit for two risers

Great , Just follow instructions in the book that comes with it .

Yes

Great question and one that i am not sure of either . I am allowed because the building owners , property managers etc give their permission to do it . Sometimes it is me and sometimes the building engineer who does it . I dont have any specific training or certifications from the manufacturer . All i have is my Journeyman Sprinklerfitter certification from my Provincial authority .So i dont believe you need any to just shut it off . You do need certification to do actual work on the fire pumps for alignments , yearly inspection etc . There is also ASTT certification to do that as well as training from the manufacturers . If anybody else would like to comment on their jurisdictional requirements please do so .

The people who do have the training to commission , align and certify are in high demand . You dont need to be a Sprinklerfitter to take the course offered by the manufacturer.

The pipe size is 1 inch , the cutting die head is set to 1 inch . It is adjustable up to 2 inch .

It depends on which sprinkler head you have . If you have a Globe 1 inch drop sprinkler head then its possible . The Globe Sprinkler Head has a deep escutcheon . Any other sprinkler head then you would need to remove the head and extend the pipe or remove the head and add a listed 1/2 inch male x female threaded coupling . Your best option would be to remove the Sprinkler Head and replace it with the Globe 1 inch drop . If it is a residential property then you would need a residential sprinkler head .

Appreciate your fast response, looks like I'll have to do some research but at least it's doable. Thanks!

Unscrew the escutcheon and see if it will give you a 1/2 inch gap before it comes off . If it does then your lucky . Also look at the deflector inside the sprinkler head , it should drop below the finished height of your new ceiling . If you do need to change the sprinkler head you dont need to cut the drywall ! The Sprinkler head has a special wrench that attaches to a 1/2 ratchet and it fits inside the Sprinkler head . I would recommend asking a Sprinkler Fitter to do the work .

Ya, absolutely. I just remembered I have a friend that used to work for Grinnell and was certified in sprinkler systems. Thanks!

Im never going to use the scissor cutters again ! 😂😅 that would be like watching black and white TV 🤣

If you have any questions let me know .

The video is showing how to attach to steel beams . If attaching to concrete then use 1/2 inch concrete wedge anchors .

The sprinkler drawing should indicate where the bracing is needed . Generally every change of direction is a 4 way brace , then 40 ft is a 2 way ,then 4 way at 80 ft . Longitudinal and lateral . 1 inch pipe is used for bracing under 7 ft , over 7 feet then use 1.25 inch pipe .

After 30 years of pushing that cutter around pipe my shoulders say im never going back ! If i cant cut with the exact cutter then somebody else can do it 😂😅I hurt my back last year pushing that cutter , couldnt put my socks on !

that sucks, some guys get real good cutting with the band saw, I'm 63 still cutting pipe, I'll probably have my helper do it now lol @@SprinklerFitting

Im working alone as all the fitters and apprentices are working on bigger projects with a tight schedule. We could hire 20 more if we could find them . Same with other Sprinkler companies . Im doing a 10 story office tower with 6 underground parkade levels .Originally it was 6 levels but developer decided to add 4 more commercial levels and a 30 story residential tower on top of that due to the new subway line and zoning changes . My company doesnt do residential . The schedule has been slow so im able to keep up . Its never been a better time to be a tradesman in B.C. 👍🏻

Gloves were new . Company policy is gloves at all times .
