Using glue is something i'm reluctant to use as loose particles of the glue could get into the water.

How did you guys overcome this?
I was just very careful and looked down the inlet to ensure the o-ring stayed in place.

But for the flat washer I used a product call "Yamabond" it's a liquid gasket material meant for putting motorcycle engine cases back together, it's resistant to heat/gas/coolant/oil, so it's more than stable in a cool watered down glycol solution.
