Them there magnetic cleaners/traps what that you stick in your central heating pipework.
Do they have cleanable bits inside as a rule or do some have filters that need replacing?
Thinking of fitting one after a clogged up diverter valve caused my sis to end up with a big bill. She's got one now , this would be for my system.
Any reason I can't get a used one, understand that O rings might need replacing but other than that would I be golden?

They're not THAT expensive brand new!
When my youngest bought his house one was already fitted - Magnaclean 2 - & the amount of crap inside it was astonishing.
Dead easy to service.

Lots of youtubes for it too.

Yeah, Magnaclean is best. In my opinion, most of the cleaning is completed by flushing and refilling.
Some cleaning products are slightly acidic and there might be some truth in old systems being held together by scale.
So always flush it two or three times, refill, test everything works then put in corrosion inhibitor. You can also get 247 emergency plumbing services for more suggestions.
