Water pump silencing hoses.....

Do Sure Flo water pump silencing hoses really work ??

I bought a set to find out. When I opened up the storage compartment, It came from Jayco new with the flexible hoses already on it.

It is still noisier than I like.

What the flexible connections to the pump do is to reduce the vibration of the water lines in your trailer. But the water lines can still vibrate some, and I think this is the source of the loudest and most irritating water pump noises. The cure is to trace the lines when the noises are occurring and tie or pad the lines so they don't vibrate against anything. Doing this can make a big difference.

I put foam pipe insulation where the hoses passed through cabinets and near walls and floor.

It significantly reduced the noise.

I mounted the pump to a 2" piece of ridig foam that dulled the noise considerably. Most of the noise resonates through the plywood deck where it is mounted. Having the buffer between the deck and pump helps. I also put on an expansion tank that cuts down on the on and off to keep the pressure. It runs longer when it needs to replenish but not as often. Especially during the night if someone flushes. The pipe foam is a good one too to quite the noise.

I did all of the above, but the BIGGEST difference was when I replaced the pump with a Shurflo Revolution pump. It has a little bit more flow and a little more pressure than the stock shurflo pump, but it has 4 chambers instead of 3 and it lessens the impact of each pulse. I use the old one for a transfer pump when I dry camp and need to fill the FWT from 5 gal containers.
