Westy water tank install

Hot day today, for Lower Vancouver Island, in the low 30’s. All I felt like doing after the overhead cabinet install was installing the fresh water tank. It sits against the angled back wall on the drivers side, and the drain pokes through hole in the  floor. I measured where that hole is in my ’82 Westy , but crikey, there was a dimple on the Syncro’s floor right where the hole is supposed to be. And same thing further forward for the sink drain hole.

Water tank area:

And sink drain area:

Drilled on the dimple and went under van to realise hole was right where the old Webasto heater fuel pump is. The heater is not working, and wont be anytime soon, so I removed the pump.

Using that hole as pilot, I punched out bigger hole with Greenlee punch.

And then a bigger Greenlee punch.

So much nicer than using a hole saw. At this point I wondered why the heck was I working with the cabinet in place? Out it comes and a trial fit of tank.

I stuck some closed cell foam on bottom and back of tank for cushioning and maybe reduce any sweating. Westfalia jams in fibreglass insulation on the back, against the angled wall. Then caulk the opening (I had painted cut surface) and the tank goes into the cabinet and the cabinet lowered into place.

Tomorrow I’ll fit up some sort of gasket plate or just caulk the area on the underside of van where drain emerges.

    Pretty cool! Why two punches? Needed a bigger hole for the bolt?

      Yeah, I wasn’t sure of the floor thickness and it was kinda fun to use two punches. When the first went through so easily I realised that it makes no difference really whether you use a large or small punch, doh 🙂
