If I put this in the header tank can it be left in?

Accepted Answer

You must partially drain down the system to empty the header tank then you pour in the solution.You then refil the system and leave the heting for about a month.You then completely drain down the system.When completely empty you refill the ystem ith fresh water mixed with a corrosion inhibitor.Vent all the radiators and you are protected or bout a year.RegardsDavid w.

Question 2

Is this safe to use within a system that has some plastic piping and plastic push fit fittings?

Accepted Answer

I would think so

Question 3

When you drain down after use should you open bleed valves on radiators? I can't see that instruction on bottle. Thanks

Accepted Answer

You always need to bleed the system with valves open to prevent air. You will then nee to put Inhibitor in to the system.

Question 4

Where do I put this? In a radiator bleed valve or In the boiler if so where?

Accepted Answer

Your system is probably filled from a connection to a tap. To introduce this cleaner you will need to drain (or part drain) the system beforehand to make some space. Then pour in the cleanser via the highest point, perhaps a radiator valve you have unscrewed and removed. you will need a flexible funnel or make up a copper funnel from standard components. Once that is done, repressurise the system by means of the tap. Run the heating for some time before draining down to remove the water and sludge, then flush again and finally repressurise, remembering to add the protective additive beforehand using the same entry point. If you are unsure, it would be worth finding a knowledgeable friend or neighbour to help. If you have an unpressurised system (Small second water tank in loft) then you could just pour the cleanser into that tank after first shutting off its water supply, but get someone to check what you intend to do or you might put the cleanser in the wrong tank = Disaster.
