Excellent Brand Name
16 Jun 2015
By MH001
, Leicester
" having changed some radiators at home one thing not to miss out is inhibitor.
I have used this and other brands before and all seem to work OK but it is not something you can say is fantastic on day 1 as only time will tell.
I needed a litre because of the size of my CH system combined with a good brand name and a price to match all made it fit for purpose for me. "

" Sentinal stuff seems rated by by pro-plumbers, certainly power flushing with x-800 worked well and moved a lot of muck out. So I am trusting to use the same brand for inhibitor based on the performance of the cleaner.
Time will tell if it was a wise choice. "
