    Hi,

    My radiators have recently been almost fully drained - I think there was probably some water left in the lowest rads. Is it safe to go ahead and add new inhibitor (I'm not sure what was already in there), or should I redrain it from the lowest point?

    Thanks

    Daven

    Thanks, was worried about mixing inhibitors and causing issues!

    Any recommendations for the best inhibitor?

    I prefer sentinell X100, but that is purely a personal preference, some boiler manufacturers recommend particular brands
