I don't use O-ring grease but I always make sure it is wet before reseating.
check your hoses, joins, taps etc.
fully primed? gentle rocking doesn't get rid of all air?

^ This is what I was going to suggest. Had a canister sucking air once. I took the head off it, and there was a small grit of crushed coral substrate on the seal. I removed the grit, lubed the seal (oh yeah!) and put it back together and the canister has worked fine ever since then.

Always lube rubber seals, i just use vaseline it does the trick and never had a problem. This goes for new canisters too, the rubber needs to be lubed to stop it from drying out, going hard and splitting. It prolongs the life of the seal.

It's possible that happened or something. Normally it's a real fight to get the head dogged down - this time it went on second go and I just thought oh well, a win.

Attached filter hoses, looked good, come back after a minute and floor flooded.
Cleaned up and will have a second go after tea. Used the last of the old towels as we used most camping. Really hoping second go is the charm.

Yes, it been a painful night. Just started looking around. The fluval FX4 caught my eye to see what you get for the price but it won't fit. Cupboard is 35cm wide and these are 40cm wide.

Just replace the head seal and this time lube it from day one. Pre-filter the canister by placing a sponge on the in-take this will stop you from having to break the seal every couple of months to clean it. Which is over kill IMO, then all you have to do is replace the sponge with a clean one every 10 days or so depending on your set up. doing this you should only have to clean it once a year as your removing most of the waste from the tank every 10 days or so. So much easier and takes like 30 seconds to service your filter. If you go away on holidays as a precaution remove the intake sponges all together, to easy.

I wonder if the drop onto the retaining wall did something after all.
I've got to look into pre-filters. Can you buy them ready made or do you make them?
I ended up going for a drive this morning and got a replacement at Pet Magic. PCS card came in handy for discount. It probably is a seal somewhere but this way I just have peace of mind and I can get it sorted before back to work.
This arvo I hope to get it setup and do pwc . Should be quick since I know the filter. Pinching sponge filters off old one as I'm not going to make it so heavy with ceramic media this time.

I had a bottle of seachem seed so tipped that in there to use up. Will test for ammonia tomorrow - hopefully other filters pick up the load.
A big thanks to everyone for information and suggestions.
