Cartridge works. HOWEVER !!!!!......... Request for spare O-rings was ignored. Turns out not supplied, not available, no suggestion on how to source. This means £130 after every de-scale ( London water ) or re-use O-rings which is unreliable, leading to very inconvenient trouble-shooting and further expense. How much better to supply if requested.
