It's been below freezing temperature for more than 24 hours. I would like to have water drip from faucets for tonight. How can I do the same with bathroom toilets?

 

You could prop the flapper open a little with a toothpick or something similar. The only problem is it will get lost if somebody flushes it.

Perhaps you should get some RV antifreeze.

 

I'd suggest you disconnect the chain from your handle and drop a bit of chain under the flapper. It will cause the tank to leak into the bowl just a little and will run intermittantly. And you aren't in danger of losing the chain, since it's attached to the flapper.

 

I will try the chain idea right away. Thank you.

Last year when temperature dipped to a single digit F, the line to a toilet froze, but not the toilet.

UPDATE: A knitting yarn seems to work well, refilling every 15-20 min. Tonight is about 20 deg F. Thank you for the chain idea.

 

If you are in danger of freezing water lines in Texas you have some major air leakage. You need to start finding and plugging air leaks most likely in your basement. I am just assuming you have a basement since you said the water line to the toilet has frozen before.

 

CasualJoe,
You are right on the money. Many houses in my area have a brick outer wall and a frame inner wall. There are air gap between the two and ventilation openings (that is missing mortar between bricks) in the outer wall. In my opinion this construction is not suited for extreme cold. Last winter was unusually cold, -2 F lowest and multiple days in freeze temperature continuously. Many houses had busted pipes. It was a big deal in my area. What I do now is to close the weep holes when 20 F or lower temperature is expected and to remove the seals after the cold snap. If anyone has a better way to seal the weep holes, please advise me. Thank you.

EDIT: I don't have a basement. Just a plain slab.

Weep holes

 

I am in N. Dallas. A few years ago I had a busted water pipe. The culprit is laid right next to the roof, delivering water to the bathroom upstairs. This is a poor design. Plenty of routes are available in the middle of the house.
Since that mishap I simply shut off main and drain from kitchen or bathroom faucet. This after we get our water needs done, and fetch some for home usage. Twice or so I open mains again for an hour and repeat drainage I know this may not be convenient but it works for me and we have adjusted accordingly. Just peace of mind.

P/S
This fall I plan to install a mains Wi-Fi controlled ball valve to do the same.

 

On another note what would happen if you sealed all the weep holes permanently anyway?

Perhaps you can Culk them... Then use a drill or putty knife when removal is needed?
