Fresh Water Tank Drain on '76 G/T

Hi,

I haven't yet found a way to drain the fresh water aux tank other than pumping it out. Why didn't A/S make a drain valve on these? Makes no sense.

Or, am I missing something?

Thx,

Ken in MN

Do you have a steel plate, about 10" x 10", with a center bolt through it, out in the middle of your belly pan? If so, the drain is above it. You have to take the plate down, then you'll find a stub with a cap on it. Take the cap off. That's how my '77 Safari was built before I added a better sump and drain at the edge of the tank.

Hey Zep - I think I do have a plate like that - are you telling me this is the ONLY way to drain the water from the tank? What were the designers thinking?

I have said many nasty words about this...

Take a look at the tank shape in this post. On reflection, the drain/source at the center of the tank makes some sense--the pickup was curved down against the bottom of the tank, so it really did suck out most of the water in the tank. I guess it made [some] sense to drain it here, too.

But I would much rather have had a tank that was installed with a sloped bottom toward the street side and drain from that side, too.

You can see how I modified the tank in post #73 in the same thread. This hasn't been installed and tested yet, mostly because I was waiting for warm weather so I could POR-15 the frame. That should happen next month (it's been snowing for the last 4 days here). I'm going to devise a sloped layer of insulation under the tank to ensure good drainage to the street side.
