The freeze that is coming to the Sacramento/San Joaquin region this week will be similar to the cold snaps of 1990 and 1998 that caused unprotected water pipes to freeze and burst.
Hardware stores are selling insulating foam that fits around pipes to prevent costly disasters. You can insulate several pipes for under $20, according Eric Ciraulo of Ace Hardware in Midtown Sacramento. Repairing a busted pipe plus the resulting water damage could cost hundreds of dollars.
Overnight temperatures are likely to drop into the 20s throughout much of the Valley Wednesday through the weekend. Afternoon high temperatures during that period will likely peak in the upper 40s and low 50s.
