The water pump is mounted on the floor under the sink cabinet. When it came on, as modern "on demand" water pumps do now days, it tended to be ... A.) loud, to the point that one needed to raise your voice over it to be heard. & B.) annoyingly distractive due to strong vibrations it transmitted throughout the trailer. The amount of vibration it sent out would sometimes wake people from their sleep. (OK- at least me) When I took a good look at the water pump, it seamed to me, that if I could isolate most of the vibration from the floor maybe I'd not be so embarrassed every time the sink or shower was used. Sooo... I used a piece of 1"-foam pad to isolated the pump. I removed the pump from the floor and placed the foam pad underneath it. I used hot-melt glue to secure the pad to the floor and the same for attaching the pump to the pad. I then used rubber grommets around each of the four screws that I also used to secure the pump by going thru the foam pad and into the floor. |

The view to the right can only be seen from this perspective when the sink and shelf directly underneath it are removed. Although this mod. is quite minor, it did quiet down the water pump considerably. I'd say the noise reduction percentage = ~60 to 70%. Later I installed an accumulator to also help with noise reduction. (as well as for other reasons described on the accumulator mod. page) |

I've tried other ideas as well. To cut down on the "hammering" pipes can possibly make on trailer frame, cabinets, and the floor; I've placed padding on various points where vibration could be transmitted. Since then I've learned that placing a looped section of braided hose before and after the pump can also help reduce "hammering " that a rigidly plumbed piped system can produce. |

Supplies for this mod. cost $0-. There were no supplies purchased. The foam pad, grommets, and hot-melt glue all came from supplies I had lying around. |

Although our trailer was purchased new, and our water pump works fine, I've
always had an issue over how very loud and annoying
the water pump was. Adding a "vibration dampening pad" was my
first attempt at silencing "the rumble from down
under"!
