Mixing adey and centinel chemicals

[rb1980]

Hi all . Had magnaclean installed and guy topped up with adey inhibitor . This will have mixed with the x100 that was in the system prior as it wasn’t all drained .
Have read mixed things about this . Also I have some x400 I want to run through the systems and then flush etc .
Has anyone mixed the above ? Thanks

 

[cross thread]

if i went to a system with no previous history i would have no idea of what make has been put in previously,so presumed they can all mix ok.never had an issue in 30 years

That’s what I assumed . Come to think of it I topped up with x100 last year after draining the undefloor heating with no ill affect . Have you used x400 ok In a system with mystery chemicals ?

It woiuld be better to drain the system, getting rid of the unknown chemicals, then refill with fresh water to which you add the X400. Leave this in for at least a week (there's no time limit, but it's effectiveness reduces after a few weeks). Then drain, refill and add X100 inhibitor.
