Use your tools

We were "dismantling" the whirlpool, that is, we drained all the water and tried to make the pool as clean as possible. Some of the jets, the ones with movable/turnable parts can be removed, by turning them, anti-clockwise, further than a little stop.
Well, "can" was too optimistic, it should rather be could. We couldn't find the tool we have to unscrew round objects with smooth surface, like the lid of a jar of jam. D. went to the local DIY shops and came back with three different tools.
The one in the main and in the extra helped to remove some of the jets that were stubborn, but six could not be removed, not even with brute force. Instead of risking that we break them we let them as they were.
