If pipes go through
unheated areas of your house and you need to leave a tap running
so they don't freeze, you should invest in some insulation
for those pipes, as the cost of the insulation is usually
less than what it will end up costing you to run the water
throughout the winter, especially in colder climates.
The easiest way
to do this is to use pipe wrap insulation. It looks like a
long tube with a slit down the side, which enables you to
wrap the insulation right around the pipe. They come in different
diameters so check and see what size of pipe you have before
you go out and buy the pipe wrap insulation. Then simply use
duct tape to secure it at each end.
You can also use
insulation tape for pipes, if it is just a small area that
is exposed.
