I have a Worcester Bosch 24CDi boiler with 7 radiators. Two months ago i drained the radiators down and put in Sentinel X400 sludge cleaner, re filled with water and started using it as normal. I was going to leave it in for a week then flush the system out and replace with Sentinel X100 Inhibitor. However due to the bad weather and one thing and another the X400 has now been in for about two months.
Will it have done any halm, and will it be alright for another week before i flush out the X400.
Many Thanks
Dave.
