Few plumbers on here i know.
Drained my heating last noght to fix aboiler. Even on a new systm with a double dose of sentinel inhibito my water was still black as ace of spades
Looking at magnacleans
Which is better - magnaclean twintech or the fernox tf-1 ?
Both are 80 quid. Fernox looks much easier to fit and clean but magnacleans what ive always heard folks using.
