Ceiling tiles and sprinklers

[Speleo]

Hello,

I want to change out ceiling tiles in my warehouse. The fire sprinkler heads were installed thru the tiles with a collar. Is there a workaround to replace those tiles, and trim the hole around the sprinkler, without removing the head?

Thanks

The collars come off, the head remains in place. Just be careful removing them - if the sprinkler heads have the glass type of actuator. The collars should just twist 1/4 turn or unscrew from the head.

yup and use a hole saw by hand to cut the hole using the old one as a template

Just the answer I was looking for..
Thanks

If it's the collars/escutions I have here, they are just siliconed in place and can easily be pried off.

Be careful, you do not want to break a sprinkler head, trust me.

LOL have you ever smelled stagnant sprinkler water? Certainly not "potable" or even desirable by any stretch of the imagination!

I can only imagine what 10 year old sprinkler water smells like. This building is less than a year old and had a couple fittings leak, the water coming from them when we disconnected the heads smelled like a high school football locker room.

Our sprinkler guys went to replace a leaky head back in November. They thought they had everything isolated and drained properly. They didn't. The minute they touched it with the head wrench it blew apart. Made quite the mess...

The other night we had a call from the water dept guys wanting to know if we were flowing any hydrants, nope, not us. They said it appeared that somebody was opening and closing valves somewhere in town and it had lowered the water level in both water towers.

About 3 am, 7-8 hours later, they call back, they found the leak. One of the factories had a sprinkler line break during the freeze we have had. Once it started to warm up and the ice melted, it started to flow water after everybody had went home.

Not only would I not want to clean up that mess, I'd hate to be paying that water bill.

At my place the fire sprinklers aren't connected to a water meter, it comes directly from the 12inch main to the water pump.

Sounds like they need to get their water flow alarm serviced...

 

[Scud67]

Sprinkler mains are not metered. But the flow alarm should have triggered and the leak found right away... and yes, sprinkler water is gross! It is black and nasty for a few minutes as it flushes out the lines.

I have certainly smelled plenty of sprinkler water after people broke the lines or it froze and broke. I worked at big hotel that seemed every year we had some sprinkler issues wedding dresses hung on heads random frozen lines you name it.

Well, there's one wedding dress that's not ever going to get remade into a christening gown...!
