chemical
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances, chemical compounds, or alloys. Chemical elements may or may not be included in the definition, depending on expert viewpoint.Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical.
Chemical substances exist as solids, liquids, gases, or plasma, and may change between these phases of matter with changes in temperature or pressure and time. Chemical substances may be combined or converted to others by means of chemical reactions.
My first post here, looking for some advice.
I've just had my boiler replaced with a worcester 4000 combi boiler. The engineer put chemical flush and inhibitor in when filling up, ran the raditors hot and then tested using a strip. And has left both in saying this is safe, and standard...

Some more plumbing advice, please.
I am getting a new boiler installed and this includes a Hot and Cold Chemical Flush of the system. Do I also need a Power Flush or is the Chemical Flush sufficient?

Hello,
BEFORE
I cleaned the system last year with a mains flush. There was a little inky stuff and a bit of sludge at the very end when I emptied out the rad I took off the wall, but no rads have ever had cold patches. Most pipes are hep20 but I had small section replaced by copper 2 years ago...

Good evening,
Please can I ask for some brief advice.
Last month I had installed a new boiler (Ideal 18kw) by a national firm. It's a townhouse with 4 floors, 10 heaters, a hot water cylinder and also a tank in the attic. The heaters look in good condition and have been retained from the...
I've been using Fernox F3 and on occasion Sentinel X400 to chemically flush out old 8mm microbore heating systems. I've had mixed results with both products, although they generally do the job.
I'm thinking of trying the fast acting stuff Sentinel X800, on a very old and never cleaned 8mm...

Hi Guys,
What would you recommend as the best/ favourite drain cleaner for clearing domestic drains and is it a different one for commercial ones?
I know that a snake is probably the first item to go to but what really gets rid of fat, soap and/or hair (gag) from slow draining systems...
Hi everyone, I am confronted with crumbly wall, the sort that doesnt hold rawl plugs in. Managed to hang all but one rad and made a right mess of the wall on the last 1. Now can stick my finger in the wall. Its a thick wall, going to the job tomorrow and thinking of trying again by moving the...
My Potterton Profile boiler will soon be 20 years old and for some years British Gas has been shaking its head about spare parts being available, though at the last service the engineer did admit to carrying the most needed on his van. (I've just Googled "Potterton Profile spares" and it would...
Hi Guys,
I am doing some work the pipes soon so will be draining down my system (combi bolier).
My question is.....While im draining it down, shall I first add some cleaning product e.g Sentinel x400 system restorer?
We recently bought the house and believe the boiler is 6ish years old and...
