Well I got the Dirt Devil central vac install completed this morning...thanks to having one of the winning tickets at the rally and a donation to the raffle by RV UpgradeStore.
At first I was going locate the unit in the space below the washer/dryer cabinet, but decided that there was enough room in there to add a sorely needed drawer for our (wife's and daughter's) shoes. However, I did locate the outlet for it on the back wall in there.
I did this by adding the outlet you see to the run for the outlet by the bathroom area sink. I ran the wire in the bottom side of the outlet vs the top like you see in order to give me some additional slack.
I decided to locate the dust pan the only real place it could be--under the bathroom area drawers. The wall outlet was located under the refrigerator. There was enough flexible tubing for both. I did end up buying two 90-degree sweep elbows and a couple feet of low voltage wire. I mounted the unit under the sink. I used bolts instead of the screws so we wouldn't find it laying inside the cabinet at some point.
The Y adapter came with it plus a 90-degree elbow which was too tight for what I needed.
Pretty happy with the way it turned out.
While I was in both cabinet areas I notice that the washer shut-off valves were loose. The one strap was off and had slid all the way to the floor. The other one was very loose. The wood had split and screws weren't holding.
There wasn't any room to correct it from the other side so I made a new bracket out of wood, ran zip ties through it.
Under the washer/dryer cabinet I moved the water pump to allow for more room to inspect and/or remove the screen filter. This also allowed me to add the accumulator tank that was on my list of to-do's. I also added wire loom to the ends of the harnesses for the gas detector and water pump and secured them to the floor. Now nothing will get caught or rub on the drawer when I add it.
