Hi,

The home is in the Sacramento, CA area. It sometimes gets down to 28-30
degrees F in the winter months. Last year I use that black spongy pipe
insulation to protect my pvc supply to valve lines, and all hose bibs.
This was especially difficult because the piping is tortuous, but it
worked.

I'd like to find an easier way. I've seen those green batten stuffed bags
used to protect large piping systems at industrial and office sites. That
seem like a good way, but I can't find anyting like that that fits my
needs.

Next I thought about wraping the pipe assemblies (all pipes at once,
including sprinkler valves) with either bubble wrap or that thin spongy
black or white sheets, and then covering with a tarp like material.

Some of the piping assemblies are large...2' x 2'.

Any comments?

TIA

If you can't find the semi-split tube foam insulation at a supply house or home improvement store you can always get some swim noodles and slit them with a razor knife and put the on your pipes. Cable ties or duct tape can secure the insulation. ヽ(€¢€¿€¢)ノ
