Pipes in an unheated crawlspace are the first to freeze and the first to sweat, and insulation solves both. Foam sleeves are cheap, easy, and effective on both hot and cold lines.
The cold lines
Insulating cold water lines stops them from sweating in summer, which prevents drips onto the ground and rot.
The hot lines
Insulating hot water lines keeps the heat in, so the water arrives at the tap hotter and the heater works less.
The sleeves
Split foam pipe insulation snaps over the pipe and tapes at the seams, and it is sized to the pipe diameter.
The coverage
Insulate every exposed inch, including the elbows, for it to work. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In San Leandro, this also guards against freeze damage.
The elbows
Insulate the elbows and fittings, not just the straight runs, because the gaps are where the cold and the sweat get in. Cover every exposed inch.
