This I can confirm is not true. I ran my water, but it still froze on 2 lines that I couldn’t run. Part of the pipe was exposed, but it busted even where it was wrapped.

Luckily if you are plumblingly inclined, PVC and glue is cheap. Just hopefully, your hardware store is open and has what you need in stock. I went yesterday and they were still wiped clean of some parts I needed.

Now a small drip may work if is a short duration cold spell. The number of hours below freezing for this cold spell may increase your troubles. But as with anything, your experience could be different than others.

The drop down to the washing machine always freezes at my house as it has no flow. It doesn't help that my drop is on a north wall.

We can tell who has not bought any lately, glue has gone through the roof

Well compared to galvanized pipe and the hassles of fluxing copper, PVC and CPVC is cheap and easy for a DIYer. PEX also makes things easier but you have higher priced fittings and tools needed.

It is because there is no single right answer. It depends on your home's plumbing configuration. You may not need a drip at all, you may need one, or you may need several.

For the OP, if your washer line is on an inside wall, your house is on a slab, and the lines are run under the slab, you should not have to have a drip there. If the line is on an uninsulated outside wall, runs in the attic, or runs under a raised house then it might be a good idea to drip those lines.

Exactly my thought process. Irrigation is off for winter, so probably won't even notice the extra.

Anyone have an issue where pvc pipes didn’t leak at first, but once water pressure increased to normal levels crack the pipe and leak.

I had that happen to a cold water line yesterday.

A lot of people likely did. As pipes thawed the leaks became more evident. Burst pipes aren't the only way the freezing weather can impact pipes. Any prior-existing leaks can be exacerbated by freezing, even if the pipes themselves don't burst. My neighbor just dug up their back yard because the actual main supply line ended up leaking after this round of hard freeze. We have had multiple nights in the 20s this year, but this was the first extended hard freeze, and it exposed problems.
