Once you've winterized a toilet, our Winterization Toilet Wrap helps prevent use of the facilities The purpose of winterizing a toilet is clear...to help prevent burst pipes caused by winter's cold. After draining the system and adding plumber's anti-freeze per their instructions, take this clear, 16" x 14" toilet wrap and "static-stick" it over the bowl. The word "Winterized" is boldly imprinted so no one mistakenly tries to use the facilities. Winterization toilet wrap material will not damage toilets or leave a residue. You get five static-stick toilet wraps per pack.
