In the DFW area where temps were in the teens overnight.

Master tub faucets, hot and cold, were dripped overnight. Hot water works, cold does not. The shower stall next to the tub was not dripped and that isn’t operating either.

If the cold faucet at the tub is opened and the shower faucet opened at the same time for some reason water comes out of the tub faucet. Any reason for this happening?

We put a heater fan in the shower stall to see if that helps any. All other faucets, toilets, etc are working fine.

Should the cold water faucet at the tub be opened to relieve pressure. Any suggestions on next steps to get water flowing properly?

CP - sorry to read that. Over in Flower Mound. Not a plumber. Just hope it turns out well for you. Were your facets left dripping outside?

The two outside faucets both have had covers over them since we got the first cold spell last year

I had this during Yuri but I didn’t have the cabinets under the sink open. Luckily, they thawed and everything was fine. I have 100% copper. Opening faucet at least partially wouldn’t hurt. Also maybe crank the heat up a few degrees in your house for the next day or so.
Main thing is keep an eye on it in case it leaks so you don’t have a bigger problem or turn all pressure off to avoid that all together.
Edit- don’t read the weird valve situation but I would shut things off for the night, heat up that room good, and try again at peak warmth tomorrow.

The sink faucets were good as those are more to the interior of the bathroom, but the shower stall and the tub run along an outside wall.

I plan on running a heated fan in the bathroom tonight along with the hot water as that was still working.

We have the pex pipes so hopefully we’ll be good, but won’t know until it thaws I guess.

Yes. I would turn everything on, but especially where you do not have any flow. Where you do have flow just a small pencil size of running water is fine (probably overkill, but without knowing your plumbing routing it kind of covers everything) . Freezing pipes aren't catastrophic, but what happens is pressure from the ice builds up and bursts the pipe (think like a pipe bomb).

Conversely, you can turn your water off before it enters the house and then just open everything wide open. Then you can start looking for where in the line it is frozen.

Opening valves will release the pressure and give ice a place to expand. Depending on where in your home it is located, I would also check your washing machine lines which is ones that people sometimes forget about having dedicated water lines running to it.

Had a heater fan running for a while yesterday and then last night my wife decided to try the faucets. Low and behold both the shower and tub cold water started flowing. Water pressure seems to be good and we ran everything last night with no problems this morning. We look to be in good shape now.

Your tub is likely back feeding from your shower.

The only pipe that froze in my house was the kitchen sink and it was on a north facing outside wall. Opening the cabinets and blowing a heater in that cabinet is what fixed it for me.
