## Description

Product description

Review: This Fixed My Water Hammer!! - This fixed my issue! We installed these new fancy luxury toilets in the house that brought out a horrible water hammer in the wall. These did the trick! Just make sure you use enough teflon tape. This leaked the first attempt I made. I ended up doing 6-8 wraps with some pipe thread sealant on the second time around. No leaks and the water hammer was over. My set up - 1/2 female NPT x 1/2 female NPT x 1/2 male NPT / 1/2 water hammer arrester. Noise level is low and overall satisfaction is good. Easy to replace in the future since it’s a wear item.
Review: It worked! Did exactly what it was supposed to on motion-detection bathroom faucet - Bought an automatic faucet for my bathroom. Unfortunately it kicked off after 2 second so it continually would kick off while using it and back on again and each time it was so sudden, going from all pressure to none, and created immediate hammering. Used these on hot and cold and the hammering stopped! Thanks :)
