Yip but still not required as part of install, as stated it’s personal preference and cost associated, I agree with you but the instructions will advise minimum requirements which I’ve stated and I feel at that point installers can’t be held liable, so if that’s what they advise and if that’s what’s carried out under these schemes then why should installers be held liable, unfortunately it’s simple you get what you pay for, and at £500 a day I’d happily put magnacleanse on a regular swap
