SHURFLO 94-591-01 Pump Silencing Kit - 36"

It works great. It minimizes the vibrations and thus the noise of the water going through the pipes into the pump. It's a game changer.

I had the kit in my RV for a year but didn't install it until now since it's such a pain in the you-know-what to remove the big drawer and to reach in to work on the pump. But what a difference. From a loud clackety-clack to a low murmur. Highly recommended.

This worked way beyond my expectations. It has completely eliminated the water hammering noise I was constantly getting when running water at any speed. It's also dampened the pump noise considerably. I would definitely reccomend! I'd also male sure that you top up your accumulator (if you have one) with the correct pressure to help things further.

This kit was intended to reduce noise and vibration effects on RV water systems. I used it because my pump originally was installed directly to the PEX tubing of the system. Over time, movement and vibration in the normal operation of the system led to early failure as it caused leaking. These hoses were easy to install directly. It was clear that it prevented leaks much better than to original pump installation. A+ product, well worth the money!

According to the Shurflo owners manual the pump should use flexible inlet and outlet hoses. The trailer manufacturer installed neither resulting in considerable noise and vibration to the plumbing lines. After installing these hoses the pump is much quieter and no longer fast cycles something no amount of pump adjustments could solve. Loop each hose for maximum noise reduction.
