Since I was test fitting the fridge and part of the furniture I thought I better have a look at the plumbing, specifically the waste/drain.
I removed the plastic under panel to see what I could see and also looked from inside at the pre-existing holes behind the door panel. I used a cable rod to find a route through, once I had identified this I used a drill to slightly enlarge the internal hole so the waste hose would fit (there underbody hole was big enough already).
In relation to the drainage pipe, I’d read on a forum that there’s a route through the bottom of the O/S door panel rather than drilling through the floor. This is the hole before drilling.
And the view from underneath, having removed the plastic underbody cover.
The pipe now in place.
I also had a quick look at the water tank & pump I purchased from Evo Designs.
