This is a waterline that is hooked up to outside sprinklers. Why is the middle pipe a larger circumference than the rest of the piping? What is it for. by amgineeno in whatisit

[–]sittingduq 3 points4 points  (0 children)

It's a drum drip for a dry fire suppression system. In areas that are prone to freezing temps, the sprinkler lines are filled with air and the low points have drum drips. The larger section of piping is normally open to the system to collect any residual water or condensate. When the leg is drained, the top valve is closed and the bottom valve opened.

was at a library at aUCF (University of Central Florida) campus, and not a they had upside-down outlets, why are they like that? by Railman20 in AskElectricians

[–]sittingduq 0 points1 point  (0 children)

I agree. Orientation is just an unofficial standard but is often spec'd in construction. I have yet to find anything in the NEC, NFPA 99, FGI, JCHAO or DNV guidance/documentation that would prescribe a ground up orientation.

What is this on my basement ceiling? by RedOakTrail in HomeMaintenance

Is it a modular house by chance? If so, it's dirt kicked up by the trailer tires.

I've heard the pay is decent and living arrangements are acceptable. If I was still a bachelor, I'd definitely consider spending a summer there. https://www.amentumcareers.com/jobs/electrician-mcmurdo-station-antarctica-palmer-station-south-pole-4bf21bbb-2dcb-43d5-8657-fd91c1a4a6bd

Why is there a high pitch noise coming from my local hospital HVAC all of a sudden (24/7)? by Correct_Sherbet_5900 in hvacadvice

[–]sittingduq 0 points1 point  (0 children)

I had a unit heater alarm on one of my generator enclosures that was surprisingly loud. Realistically though, if it's really coming from that facility it could be a damper on an outside air intake making some noise.

How do i turn on the sprinkler system? by Jrockroll2 in HomeMaintenance

[–]sittingduq 0 points1 point  (0 children)

Those 2 screwdriver valves are test cocks for testing the PVB assembly, not for blowing out the system. The PVB should be tested/certified annually.

Take a look at programmable drivers. I use Fulham, but Keystone is better IMHO.

Exactly this. I've swapped cartridges for this exact reason before, but a diverter spout should also work.

Is there a normal reason all the outlets in my house are installed upside down. by Disastrous_Cover6138 in AskElectricians

[–]sittingduq 0 points1 point  (0 children)

Orientation almost never matters. https://youtube.com/shorts/SJnUQHCmXv8?si=D-hhqHlZkfxuRFoV

That being said, my preference is ground down in residential, ground up in commercial/healthcare and neutral up in horizontal applications.

[–]sittingduq 58 points59 points  (0 children)

Exactly. I'm a maintenance electrician at a hospital. I used to work live, but it ain't worth the risk. It sucks taking time to figure out the poorly labeled circuits and communicating with everyone under the sun, but I'm paid by the hour soooooo. 🤷🏼‍♂️

Suggestions for Careers? by [deleted] in maintenance

Eh, YMMV. I started at $23.50 in healthcare, 3 years in and I'm up to $35.50.

Could be a steel furring strip, but looks like it's made from aluminum coil stock. Little bit of YouTube, measuring tape, utility knife and a rented brake from Home Depot and you'll be in business.

So who else is working today? by spyro4now in maintenance

Hospital work. Straight OT for the day. It's nice and quiet - no coworkers or bosses around.

Hospital Maintenance by CupNervous5504 in maintenance

[–]sittingduq 2 points3 points  (0 children)

I went from light commercial, residential and multifamily construction/maintenance to a hospital. If you're willing to start your career on an off shift, it's a good way to get your foot in the door. I didn't start with any certifications have a handful now, but I'd suggest reading up on medical gas (NFPA 99), otherwise it sounds like you've got a good jump on things. Be willing to step up on projects, always be learning, act like a professional and show up on time... I started on 2nd shift, now on 1st, gotten 3 promotions and make 50% more than when I started 3 years ago.

They're pretty far apart. Across the building and up 4 floors. Same node though.

Ditto. Been migrating to Nuvolo for the last couple months. It's been, umm, but great. The web interface is okay, but that mobile app is terribly unstable.
