The shower tap in my swift leaks I want to change the ceramic cassette but its secured using a 30mm plastic nut which is recessed in the tap assembly. Due to this I cant get a tool on it to unscrew it, does anyone know of the correct tool to get it out.
I have exactly the same problem.
Its a Swift Challenger 2005 with a micro switches and not a pressured system.
Over the years on different caravans I have replaced the mixer cartridge with no problems.
Normally you take the top off and unscrew a big brass nut.
This time its different. No big brass nut to remove but rather some form of insert.
I can't see how to remove the insert.
I tried holding the outer with big pliers and moving the insert with nose pliers but it would not move.
Its not threaded seems to be some sort of locking mechanism?
Frightened to use too much force in case I break something.
I have looked at all the Youtube videos - they are all for the "big brass nut" type of fitting.
My closest Swift dealer is about 90 miles away so that's not an easy option.
Any help would be appreciated.
