Water bottle

Hi, I am new here and not familiar with forums so hopefully this is in the right place (sorry if it isn't) and that I am doing this right.
I have been looking and looking for a water bottle that doesn't leak!! I always relied on these as they have been great, fit the cage perfectly and never leak: https://www.amazon.co.uk/SystemsEleven-Plastic-Cockatiel-Dispenser-Transparent/dp/B00PQZ4BM2 and bought a few spares but they are no longer selling them and the remaining one is in need of being replaced. I've searched for these using reverse image, etc. Sadly no luck.
I have the Hamberley flight cage so not all bottles fit either. I've tried many water bottles (from pwt shops and online) and they all leak and leave the cage and floor wet and no water for drinking or it doesn't fit the cage so falls off! I have tried with a bowl but he will not drink from it though he will eat his seed from a bowl!
Very frustrated and just wondering if any one has any good water bottle suggestions or know where I can get the ones above. Note, I am in the UK.
See image below of the water bottles I had been using.
Thank you.

I am not a fan of water bottles, as they can get clogged without you knowing-- plus, they tend to be bacterial harbingers..I know dishes SEEM dirtier, but if you keep up with them, they are much cleaner (in my opinion).

I have tried with a bowl but he doesn't seem to understand it's for drinking! He will bathe in it but not drink and I wouldn't want him to go thirsty. I guess he is used to a water bottle as they always had them (he's around 6 now). I do get what you mean though and I don't think it is actually any dirtier using a bowl, I have been trying that with him. Thanks.

I guess you could do both-- I just strongly prefer the bowl but I get what you mean.

This is the one I use.

Currently with working-at-home I've removed them from the cages. And I have always made sure the birdies have full clean water Dishes as well.

But for me these are security if leaving for the day. (What-IF i didn't make it back that night? In case of disaster they will have water to last for several days.)

We put 2 of them in our African Grey's cage.
