Product review (5 stars): Super easy to install on a dishwasher
I was initially confused as to whether I needed this product or&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Sioux-Chief-Mfg-660-TC1-3-8-Inch-OD-Compression-Mini-Rester-Residential-Water-Hammer-Arrester/dp/B004678IXE/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Sioux Chief Mfg 660-TC1 3/8-Inch OD Compression Mini Rester Residential Water Hammer Arrester</a>&nbsp;to install on my dishwasher.  This one screws in directly to the stop valve and requires only one compression joint between the arrester and the water line supplying the dishwasher.  The alternative 'tees' into the water supply line requiring 2 compression joints.  Fewer compression joints = less to go wrong.

I had to cut back my water supply line about an inch or 2 using&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ridgid-32975-1-8-Inch-to-5-8-Inch-Close-Quarters-Tubing-Cutter/dp/B000LDGNCU/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ridgid 32975 1/8-Inch to 5/8-Inch Close Quarters Tubing Cutter</a>&nbsp;for the supply line to fit into the arrester once installed.  I placed a few wraps of teflon thread tape on the stop valve and secured the arrestor, then installed the supply line to the arrestor.  I tightened the nut enough for the brass compression piece to stay attached to the supply line, then removed the supply line and applied a few wraps of teflon tape over the compression piece, then secured to the arrester for the final time.

Took about 10 minutes (first time I'd ever attempted this) and instantly stopped the loud bang I heard everytime the dishwasher's water valve closed.

Perfect piece of equipment and will now install another 2 (different) arresters on my shower.

100% recommend.
