Question DetailsAsked on 1/7/2018

what should i do about my water pipe that came apart and i don't have a plumber yet in the cold weather,

i had a water leakage, 1st thought was a burst pipe, after careful inspection, i noticed the water pipe that twisted together had came part. its very cold out side. The water pipe is in between my foyer and car garage. the end of the water pipe already froze. im waiting to hear back from a plumber, any suggestion what i should do next. I'm worry that the open area of the unattached pipe thats already frozen may freeze my entire water pipe.

I would bet it did not just "twist apart" - if you look close or try to screw it back toegether you will probably find the threads have been stripped. End of pipe probably did not "already froze" - an open pipe with water pressure will not freeze up till about 30-40 below, so it probably froze solid and that caused (by pressuring up the water in the pipe between two frozne spots) the broken joint.


I would not worry about the exposed end freezing it up faster - the whole piece of pipe sounds like it is exposed, that will cause freezing faster than the air at the open end of the pipe (because cold air will no actually be circulating up into the pipe). Exposed or open end will make negligable difference in freezeup time if no water is flowing through it.


Realizing this will flood all over when the pipe thaws, try to find a shutoff valve which will shut off water to that point - may or may not be one which does not also turn off alll water to the house. (And turning off the main shutoff valve stops all water circulation, if this is not the main feed to the house - promoting faster freezing because there is no water flowing, bringing in warmer fresh water from underground.


I would try to drain the water out of the fozen section(s) of pipe by opening faucets - and (bearing in mind these are open when the pipe is thawed out and reconnected) leave them open to relive pressure from the remaining water in the pipe freezing up. This includes shutting off valves feeding to water filters, washer, dishwasher, etc which might see pressure from freezing pipes. Obviously, in any part of the house with current water pressure and use, frequent use will prevent excess pressure buildup - but that does NOT occur overnight or if away in day at work, so generally you end up shutting off the incoming water supply at the main shutoff valve, then draining out all pipes as much as possible (using indoor and outdoor faucets), and keeping the pipes warm with house heat.


Which of course means no water in the house till a plumber can get to you.
