Welp Just figured out the cold water line to my washing machine is frozen. Same line froze during the last arctic blast when it got down to 1° Pulled the washer out and put a heater facing the wall. That worked last time.

What's great is the wife has found a multitude of projects costing thousands of dollars. New windows, insulation in the main attic and the latest is balancing the hvac systems in the house cause a bedroom is too warm and the main room which has 35 ft ceilings is not. Fml.

But then new cold water would have to flow into the water heater, right?


Yeah, but that doesn't mean it's moving any water around the cold water lines running everywhere.

If your water heater is connected to the main near where the water comes in, then its not moving any cold water anywhere else.

Best to drip from each faucet.

tankless water heater on the side of your house from freezing up.

Anyone with newer construction and tankless water heaters on the side of your house need to check those lines outside.

Take the cover off and make sure the pipes to and from the heater are insulated.

Also the hot water demand has to reach a certain threshold before the heater will kick in. Dripping faucets won’t reach that flow demand, so it’s a good idea to turn on the hot water to sinks, tubs, showers periodically to get hot water flowing and the heater heating.

Also, a lot of people will stay below freezing throughout the day. Stay vigilant. Pipes can still freeze during the day, and especially later this afternoon when the sun starts setting and temps start plummeting.

this is good advice. Water can struggle to stabilize just above freezing for a while and it won’t take much of a drop to freeze up quick. This evening is the danger zone

Currently have PEX water pipe frozen going to my upstairs. Rest of the house is fine. The pipes run through the walls which are insulated but said wall is between master closet and garage (which is not heated). therefore I can’t get access to it to thaw it out. Should I be worried?

Also, is it a bad idea to leave hot water faucet open even though it’s not running since it’s frozen?

Cut off water at the street last night. Turned it back on to get cleaned up when temps got over 32 earlier. Cut it back off now. No danger of burst pipes.

That is completely untrue.

Terrible advice, no on listen to this.

All good. Pier and beam house. I run water through my pipes every few hours instead of dripping. Got up at 4:00 am to run water through my lines. Will do so occasionally during the day since temp will remain below freezing. All good.


I do the same. No problems.

I had a short piece of PVC in my chicken yard that broke. I had used PVC for the last section because I couldn't find a PEX-to-waterer adapter. I went PEX to PVC to waterer instead.

Cut off the water supply and drained the lines before the freeze. Apparently that section of PVC was on an incline and didn't drain, so I found it exploded this afternoon. The adjacent PEX was just fine.

Did you blow them down after shutting off the water because that water is still in your pipes.

PEX can indeed freeze and burst. However, it has much better expand ability (versus copper,PVC, & CPVC) and will return to original state once thawed. But can burst in the right circumstances.


Just for clarity,(per a failure analysis I read once) the cause of the burst water pipe due to freezing isn’t the localized area where the ice plug actually occurs.

The mechanism that ruptures the pipe is the pressure created against the liquid contents when the newly formed ice plug acts like a piston and tries to compress the water in the pipe.

When that happens the pressure increases until the pipe ruptures.

The pipe can likely take the deformation locally caused by the ice formation.

Edit… this isn’t an engineering study and I know there are exceptions.
