Sentinel X800 Ultimate Cleaner 1Ltr
clients 8mm microbore system was blocked. I had to cut out the cold fill and replace but trusted the cleaner to clear the inaccessible block in the manifold and return pipe work.
Within 1.5 days the upstairs was unblocked and working better then ever

Really good cleaner
I regularly use X800 for heating and chilled water systems and it does the job well.
Screwfix have this on a promotional price at the moment and its a really good price.
Would recommend this product highly.

Central heating cleaner
due to the problems that i was having with my CH system i thought i'd give this product a go. firstly i flushed my system through before adding this product , i then waited 7 days as instructed before flushing the system to clean. It seems to have worked as intended. The radiators are now heating up as intended. Very impressed with the product.

I live in a very hard water area and even though I have a good solution of inhibitor, I still get reduced water temperature every couple of years. This product cleans the system and the results are almost immediate. I leave it cleaning for a week, then flush the system and add inhibitor again. 5 years ago, I was advised that I needed a new heat exchanger in the boiler at the cost of over Â£200!! This product is much better value.
