Not sure what this particular jet is called (pic1) but it's the largest one in the tub. I’m wondering if it can be serviced from the back side? It has two caps on what looks to be a collector of some nature (pic 2). I can see a bunch of junk inside the collector where the arrow is pointing. I would like to clean this out but I’m not sure how. Can those caps be removed? Any advice would be appreciated.

the jet dismantles from the front - twist lock the escutcheon off, unscrew the centre nozzle, remove the outer cone and you may be able to flush the debris out.

alacy,

Thanks for the quick reply. How do you "twist lock the escutcheon off"? It doesn't have any notches for a screwdriver like the smaller jets. Do you press down and twist counterclockwise?

yeah - pretty sure its a slight twist anti clockwise to release the front escutcheon then you have open access to undo and remove the nozzle and cone
maybe someone else can be more specific - haven't pulled many out for a fair while

That did the trick... thanks.
