Review: Produto muito bom
Review: This pump is noisy. It's not the first pump I've used/installed and this is no better than 20 year old pumps I've replaced. Considering the technology available it's sad that these pumps still shake too much when primed. They rattle everything around them. It works well but the low noise advertising isn't accurate at all. Try something else if you need a quiet pump. I returned this one.

### ⭐⭐⭐⭐⭐ Review
*by A***W on 8 December 2025*

this is a really great pump with really great suction and output pressure (for 1 faucet). Installed 2 in my 4x4 rock crawler, 1 to run a hose, then a second one to refill the reservoir via suction. For the price it's unbeatable, but it is quite loud when running so be aware if that's something you care about
