Help with inflating La Bassine

[possum]

I borrowed a La Bassine pool from a friend, and don't seem to be able to find an air pump with an appropriate adapter size to inflate the darned thing.
I got a Coleman hand pump that has four adapters one of which almost fits into the black valve. I also purchased a Black and Decker electric pump which has three adapters that are all too small.
Can anyone tell me a pump that I can buy that has an adapter that actually fits into the black valve?
I need to get in touch with the mama who lent it to me, but I'm freaking about it tonight since we just tried out the second pump I bought, and it didn't work.
Thanks,
Melinda

I have 3 LB for clients to use. I use the large black hole with a larger adaptor (which doesn't fit perfectly but close enough) to initially inflate the pool, close up the black screw on cover tightly, and then use the smaller clear airhole underneath the black one with a smaller adaptor to "top it up".

We had an adapter that fit onto our shop vac perfectly and over the large black valve, and then a smaller one that fit into the small valve for topping up. Most vacuum cleaners would also work I think if you can reverse the air flow to blow instead of suck.

We used the pump we got from Target-- actually it started dying right when we were test-running the pool so that was good, went and got a new one, we've been using the old one for a couple years for the air mattress for guests-- it's just a simple pump from the camping section, by the inflatable mattresses. It has lots of adaptors and DH was in charge but said it was no problem, fit well. He may have done the floor by hand with the birth ball pump, when he was waiting to go to Target for the new pump, I'm not sure...

I believe we bought a electric pump from the camping section of Walmart and it fit perfectally.

Maybe La Bassine or a company that sells them can point you in a reliable direction as well?
