Sentinel X400 Sludge Remover Rapid Dose 300ml is rated 4.3 out of 5 by 8.
Rated 5 out of 5 by from I will use nothing else, this aerosol is amazing! This aerosol is great. No messing about with the 1 ltr bottles. No mess or waste. Can use from two hours to 4 weeks in the system. But you must get it out!

Rated 1 out of 5 by from Definitely avoid the rapid dose Bought 2 bottles of the rapid dose x400, 1st bottle didn't work as it didn't have enough pressure and the solution trickled out off the bottle. The plastic connector on the second bottle snapped off inside the Maglean dosing valve. I had to remove the Magclean and spent around an hour picking the plastic out with a pin.

Rated 5 out of 5 by from Easy to use and effective This is the first time that I have used the X400 rapid dose product and I have to say that it was really easy to use and very effective at clearing the blockage caused by sludge in a large radiator. The application tube fits easily into the bleed valve of an isolated radiator and fully feeds into the rad within 30 seconds with no mess and no need to drain the system.

Rated 4 out of 5 by from Sorted underfloor heating that stayed cold Had 2 underfloor heating loops that stayed cold . Ran this around for a couple of weeks and they heat up now . Be sure to flush throughly for the system otherwise you’ll just move the sludge to another part ..
