I used the back end of a ballpoint pen (perfect fit) and a rubber mallet, it was not easy and I had to strike it pretty hard several times in a row. If you also decide to do this, make sure to use something malleable like a pen because a metal tool will likely damage the ball. Other than that, I totally think it was worth it and the product itself does the job. ## Frequently Bought Together - HYDRO MASTER Water Hammer Arrestor,Clean Brass,1/2"MNPT - Joywayus Brass Pipe Fitting Barstock Tee 3 Way NPT 1/2" Female x 1/2" Female x 1/2" Male Hose Fitting - 2-Pack EFIELD MH-131, 1/2-Inch MIP Thread Stainless Steel Water Hammer Arrestor For Potable Water Plumbing Application --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/240412971-hydro-master-water-hammer-arrestor-clean-brass-1-2mnpt](https://www.desertcart.pe/products/240412971-hydro-master-water-hammer-arrestor-clean-brass-1-2mnpt) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-08-15*
