Silencing the water pump, etc.

During our first trip my DW asked if the water pump had to be so loud. Of course I responded "No dear". I am always looking for the flimsiest excuse to mod the Scamp so I dove in after returning home. Turns out the hatchway Scamp provides to access the pump is too small for easy access. So the first step was to enlarge the hatch. I also added ventilation holes since moisture accumulates on the wood under the bed cushions in cold weather.

Originally the pump seemed to resonate thru the wood floor despite its rubber mounting. I decided to suspend it completely with some plastic strapping. This involved two wood additions. First I made a small tray the rests atop the wheel well. It is attached to the pantry wall not to the wheel well. Then an 8 inch square piece of inch plywood is suspended from this tray to hold the water pump. There is no rigid connection between the pump and the trailer. At the same time I added flexible hose at the pump connections to lessen vibrations traveling along the original pex tubing. While at it I added a two gallon accumulator tank ($38.00 at my local plumbing store/Menards) to lessen pump cycling and water surging at the faucets.

So far its much quieter and the water flow is constant, more near what we get at home. An added bonus is the easy access for storage around the water tank. Bonus two is an extra "gallon" of water capacity. Bonus three is no more pump cycling during those late night bathroom visits.

I left open the possibility of adding padding under the pump but the Scamp bubble wrap and rat fur covering the wheel well seem to do the job.

Cheers , john

Yeah the extra storage access is nice. I considered moving the water tank 3 inches one way or the other. Scamp plops it right in the middle making storing other things difficult. Moving would mean relocating the drain which seems easy. I am a bit more concerned about the fill tube. Stay tuned.
