Product review (5 stars): even a woman can install it !!!
I recently bought a lg washer and dryer(front loaders) and i too was having really bad water surges.. I looked it up on the web to see how to solve the problem.. found out i needed a water hammer arrestor.. went to lowes bought one for $10.00  came home and installed it,,,WORKS PERFECT,,NO MORE SURGES,, took me about 5 min to install..  great product and would highly recommend to anyone who is having this problem,, HONESTLY i did not even know this  problem existed until one day i had the washer on,, pulled out my refrid, to clean behind it  and saw my water line to the ice maker jumping when the washer was filling,,,not good for pipes i thought,, so i solved the problem!!!!
