OBTW, dripping water faucets do not help if it gets cold enough after you lose power. Otherwise, the Arctic/Antarctic would have never frozen up because their water was "running".
I live in a mobile home that depends on heat tapes as well as wrap around the pipe insulation. If/when the heat tapes go out, dripping the water doesn't always maintain the water running.
I lost my hot water Monday during an extended power outage from 7 am to 11:30 am. I managed to keep the cold water running by dripping/flowing it.
However, I just confirmed at least one broken pipe and still don't have any running hot water.
Just turned off the water to save on my water bill.

I have an on demand hot water heater run by propane and it almost froze a couple years ago, I insulated the heck out of it with the help of a plumber friend, and now it lasts thru the coldest winters here so far. I'm in North Carolina just North of Myrtle Beach so it gets below freezing but not for weeks on end or even normally days on end. It will get into the teens and single digits some Winters but during the day it's usually sooo sunny that it pops up 10 to 20+ degrees above the night time lows.
Liquid water is densest at about 4 degrees Celsius, compared with ice at zero. This is why bodies of water freeze from the top down, not the bottom upwards. Hence the water in your pipes on their way towards freezing go through the state of greatest density first before they freeze. When the water freezes the pressure produced with expansion breaks your pipe - but only if the water has no where to go prior to freezing. So it is an open tap that allows for the expansion of said water when going from 4 degrees to zero without any pressure buildup. A side-effect of an open tap is usually water flow, providing it is still liquid. Presumably flow keeps any centres of crystallisation moving out of the pipe as well.
Indeed flowing water colder than zero can be kept from freezing, where the stirring effect of flow prevents ice lattice bonds from forming for long enough to become fixed. The trick is to start the flow before zero is reached, and keep it going after the temperature goes below that of static freezing. Of course this also depends on the surrounding temperature and how quickly it changes, compared to any heating methods.
I'm sorry you are all having so much trouble. :-(
Cheers, Mike.

The other thing is the water in the pipe in the ground coming into your house is warmer than freezing, so if the flow is set right, the water never reaches freezing before it exits your faucet. That will be a lot more than a drip.
Oh yea Cancun Cruz ... What? My subjects have no water? Can they not eat the snow?
There's nothing I can do about the power companies so I've decided to finally get a dual-fuel generator, but I'll run it on propane because the fuel will last a long time and the engine won't gunk up with gasoline muck. I'm going to get a Champion generator, two propane tanks, an electric heater, and an electric hot plate, and I already have some electric fans. I can muddle through the next outage in either winter or summer (summer without AC can be about as bad in the opposite direction here).
Party on.

I have a whole house generator that runs off an in ground propane tank, it's a 23kw but rarely runs fast enough to put out that much as I shut things down, ie pc's, when the power goes off. It cost me 10k for everything dune and dusted and automatically comes on when the power goes off and does an auto test every week as well. I have heat or a/c as needed as well as tv and internet too, the fridge runs and the electric stove runs too. My water heater is propane powered and on demand. The generator at full power will use about 4 gallons of propane per hour so my 250 gallon tank will last about 50 hours because they only fill the tank to 80% full.
I come in for a beer and all I hear is about the freeze in Texas. As for me, I was in Mexico during all that. Came home to a non frozen house...why? Cause a decade ago my pipes didn't freeze but did slow to the point that it caused water damage requiring pulling the floor boards and sheet rock. After that I dug up the waterline and insulated the whole thing. Houses in Texas are not designed for prolonged winter weather. They meet the minimal standards as set by the government. If you want something more, you are going to pay for that something. I've spent the last decade retro fitting the house. Better insulation in the attic (expaning foam under the roof and blow in on top of the ceiling, Propane tank, Water well, Double pane windows. Better exterior (Winterized) doors. The only thing I can't add is a propane or wood fireplace. I would if I could but the cost is way too much.

Barkeep...Where do you keep the liquor!!
Around me there are often propane fireplace inserts for sale when either people remodel or didn't plan correctly and got the wrong size one for their home, I see them on FaceBook either in the For Sale in 'your county" or in FaceBook's Market Place. I'm in North Carolina very near the South Carolina line so a wood burning fireplace isn't needed and would roast people 99% of the year but ALOT of homes, especially the new and remodeled ones, all have propane fireplaces in them. I put a fan on mine so it blows the heat into the room which makes it really nice on those cold mornings when I turn the heat down at night.
Campus IS&T will be installing upgrades on the Earl Warren Data Center network on Friday, May 21, 2021, between 6:00am - 7:00am.
The upgrade is being performed to improve connectivity between the Data Center and its hosted users.
During the upgrade period, all Haas services hosted within the Data Center to be unavailable.
This will include drives and systems on Tableau, SQL (database-related), and the XLab servers. Access may also be unavailable for the following: EMS room reservations, printing, programs and research applications on the Haas Terminal Servers (which rely on license management), and all network drives (H:, G:, O:, and I:).
ACTION REQUIRED for Haas Data Center Accessors: It is recommend that all work on these systems be saved and closed prior to the upgrade schedule to avoid any data corruption or loss.
For detailed information, please visit this Campus IS&T announcement page. For questions, please email helpdesk-[at]-haas.berkeley.edu.
