Review: Solved water pump hammer on a boat - Straight forward installation. Decent quality. Solved severe water hammer issue that was noisy and bad for the system. The pump runs less, is quieter and the flow has smoothed out.
Review: worked as designed. - Did the job. Added it to the boat fresh water system, the pump noise is too quiet now, hard to tell if it is running. Should have bought the 1l version but space was an issue. Functions right out of the box for us.

### ⭐⭐⭐⭐⭐ Solved water pump hammer on a boat
*by R***. on August 16, 2025*

Straight forward installation. Decent quality. Solved severe water hammer issue that was noisy and bad for the system. The pump runs less, is quieter and the flow has smoothed out.

### ⭐⭐⭐⭐⭐ worked as designed.
*by B***D on January 19, 2026*

Did the job. Added it to the boat fresh water system, the pump noise is too quiet now, hard to tell if it is running. Should have bought the 1l version but space was an issue. Functions right out of the box for us.

### ⭐⭐⭐⭐⭐ Quieted down my pump and reduced pulsing at low pressure
*by C***S on April 1, 2025*

Smoothed out water flow. Really easy to install and tune properly. Make sure to set it roughly 3 psi below your activation pressure. Keep in mind that while it can be mounted in pretty much any orientation, it is best to keep the inlet and outlet on the bottom such that it will drain and not retain water so that it can be winterized properly in an RV setting.
