Love this power flushing lark.
Is it true it only cleans the system to around 80% clear?.
OH! and found this from the advocate of clean flushed systems

The treatment manufacturers dont help.
They do not make it clear just what their concoctions actually do. Nevertheless after X400 has been in a system for 4 or 5 weeks the colour is quite dark and I had always immagined ( hoped ? ) that it had dissolved the sludge. It certainly quietens ci boilers!
I cannot see much sludge being flushed out of a system by fluid movement alone. At least the acid treatments do work very well.
Power flushing to me is primarily a show for the customer. There are few situations I see it doing any better that the correct treatment left for the appropriate time using the system boiler and pump or in extreme cases mains water pressure flushing. X400 does need four weeks of heating use. Only the acid treatments will be completed in a few hours and I only use them in the worst cases.
There are two main sludge constituents, oxides of iron and oxides of copper with only small amounts of other materials. Almost any acid will dissolve these and hydrochloric is the cheapest to buy. I have only used this on disassembled components mainly because of others alleged concerns. I wonder why so few people use it on whole systems. I have not heard of any genuine bad experiences using HCl.
Interestingly the Fernox test kit will measure concentrations of both Sentinel and Fernox although they say they operate on different principles. Sentinel told me it is " based on Molydebenum " but they also mention " organic compounds ".
The man at Purimatchos when asked if his products were approved by benchmark replied " Whats Benchmark ? "
