Question: Is there a more environmentally
friendly solution for preventing pipes from freezing other than using
antifreeze? We have used antifreeze solution for years in our Lake Tahoe
vacation home; however, I have become increasingly concerned about pouring
antifreeze down the pipes.
Answer: I understand your
concerns. All of us need to be more conscious about our environment and it
truly starts in our homes.
To begin with, there are a number
of non-toxic antifreeze products on the market today that are designed to be
used in the home. |

If you are using antifreeze, make
sure you use one of these types. RV antifreeze products are specifically
designed to be used in the home. It is non-toxic and odorless and it is safe to
use with steel, copper, brass and plastics. When used at full strength RV
antifreeze is designed to provide freeze protection to -50°F. You should be able
to find RV antifreeze at any home improvement or hardware store.
If you would still prefer not to use
antifreeze, then you have a couple of other alternatives to prevent your home’s
pipes from freezing.
First, you can choose to drain both
the supply and drain pipes. Usually it is a good idea to hook an air compressor
up to the supply lines to blow out any residual water. Also, you will want to
seal the drains to prevent any gasses from working their way into the home. This
includes plugging the toilet bowls, e.g. with a cloth rag.

Second, you can wrap heat tape around the supply lines and just drain the drain
pipes and toilet bowls/tanks. Again, you will need to seal the drains. This
method is a little risky if your home looses power for an extended period of
time.
Lastly, you could choose to leave the
heat on at a low temperature (e.g. 50°F - 55°F), to prevent the need for
draining the pipes or using an anti-freeze. |
All of these alternative methods for protecting your vacation home’s plumbing
pipes have their pros and cons. However, if you plan on leaving the vacation
home closed up for the entire winter, then draining both the supply and drain
lines makes the most economic and environmental sense.
