Frozen outflow valves (both gray and fresh water)

Hello, there has been tons written about not letting the water to freeze. But during our last winter trip, although we kept inside toasty, the outflow valves (both) froze during the ride home (long evening trip, under -5C whole time). So I got left with liquids in both tanks but unable to drain them.

Since both outflows are behind underside covers with our T6.1, it's not that easy to access them directly. The best I could think of was use of hairdryer to indirectly defrost the outflows. For the grey water, I've pointed the dryer into the hole right below the valve from the inside cupboard:

And for the fresh tank, I did the same but from the outside, pointing into those portholes in the cover:

With a huge relief, after several minutes (well, 15 in case of the grey tank), the water started to pour out.

So, the reason why I write this is twofold:
- Might come handy for somebody else in same situation :)
- More importantly - since I don't know much about how it looks under the covers - can somebody think of better, less tedious, way how to defrost that? Or is there something I could damage with this setup? (I've used some middle settings on the dryer, but still, I have no idea what is actually inside those areas).

Just for reference, some other threads dealing with water freezing:

Thanks, Jakub
