The Water Ram is a drain cleaning device that uses kinetic energy to unclog plumbing fixtures, and eliminates grease, hair and sediment from lines. Best part is anyone can use it- just pump the Water Ram, insert it into a drain, and snap the trigger. Think of it as a super plunger.
With any drain cleaning tool be careful if you have used any drain cleaning or dissolving chemicals prior operation, and always wear proper safety apparel.
