To Flush or Not to Flush


Postby Andy16802 » Fri Jun 29, 2007 9:22 pm

I have recently moved into a house approx 20 years old. Some of the radiators have been replaced and some not so I am going to replace them all over the summer as the older ones have been painted several times and look shabby as well as having some bad corrosion around the bleed valves.

My question is whether I should flush the system through with a sludge/scale remover or not to clear the pipework. I have had various views on the subject some saying yes and others saying no because there is a chance that flushing could open up any small leaks that have self sealed/scaled up over the years.

Am I going to cause myself more problems by flushing the system with a chemical or should I just drain down and refill several times over with just plain water ???

Any comments from past experience would be most appreciated.

Many thanks.

hi andy most sludge accumulates in the radiators /boiler/and pump if you intend to replace rads do them all at once this will remove most of sludge then buy sludge cleaner/ neutralizer/and inhibitor follow instructions on bottle its a long job can be 4/6 hours or get the system jet flushed by a contractor all the best john
