Can shower drain pipes freeze?
Also, how do you thaw a frozen drain pipe?
To unfreeze a drain pipe that hasn't been frozen very long try just dumping some hot water down the drain. Fill a pan with water, and warm it on the stove. Once it's almost boiling, carefully pour it into the drain. This may just be enough to break through the ice and unfreeze a drain completely.
Likewise, can a drain pipe freeze? Building drains can also freeze and break, including fixture traps and building drains. In freezing weather a slow drip or water running slowly into a drain pipe can lead to ice build-up, a frozen or even a frozen and burst drain pipe, or a water backup into the building.
Subsequently, one may also ask, will pouring hot water down drain unfreeze pipes?
If you need to unfreeze water pipes, leave your faucets open slightly to help thaw out the pipes. If you find a leak, close the main shut-off valve to your house and call a plumber immediately. Pouring salt or warm water down your drains may also help thaw out the pipe faster.
How do you thaw a frozen drain trap?
Start as though you are going to root out the trap. Take the overflow cover off and run a tube down with hot water flowing through it. As it hits the ice and melts it, keep pushing it down. When it stops coming back up the tub drain, you are done.
