We all know where water likes to collect in a fuel or oil storage tank... right at the bottom. This common problem can rust the steel tank and damage the equipment attached to the tank. The question is, what to do about it? Often siphoning cannot get all the water, and wastes some of the stored product as well. We have a better solution. The H2O Water Worm is a 1.5in x 48in cloth sock containing our amazing water absorbing desiccant. Simply drop the Water Worm into the tank via any convenient opening, being sure to hold onto the attached 7 foot cord. Secure the cord outside of the tank. After settling to the bottom of the tank, the Water Worm will absorb any water that has collected in the tank, but will not absorb any oil. To check or remove the sock, simply use the attached cord to pull the Water Worm out. If it is firm and full, it is spent; if not, put the Water Worm back in to collect more water.
