VEVOR Pool Drain Hose, 2 inch by 50 ft, Durable PVC Material, Includes Aluminum Camlock C & E Connectors and Clamps, Fits Pumps and Sand Filters, Ideal for Pool Water Removal, Blue

Yes, good hose. Will hold water or ice

I've not had any issues at all with leaking. I drained my koi pond, with this hose and ran a half acre, even up and over a fence. I also cut the hose in half. I am getting ready to use again to drain the dog pool and some things that I left out before I checked the weather report!

I’m pretty sure that it would work in the manner you’ve described. It’s very strong. I use it to pump down pool after a heavy rain and or backwash the pool filter . Sometimes i step on it to remove the water as I fold it up . I use a pool cover pump to way it down but the hose should work . Hope this helps.

Try sand.

Possible, but I'd be skeptical

Hose does not leak.

In my opinion that would probably work. At least for a while, depending on your climate

I would think it would, the house it self is very durable, not sure how you plan on clipping the ends, that's where you may have a leak if not done correctly.

Just as long as it isn't punctured shouldn't have no problem sounds like a good idea.
