Some of those inhibitors like city plumbings brand are brown in colour. I know that but some people get confused. Happy Xmas Derrick .

Orange? My system is unbelievably squeaky clean, It’s got an Orange tint because that’s the colour of the inhibitor, Inhibitor says over dose won’t affect boiler ect. Just saying 🤔

It's Corrosion acidity/ Magnatite we check for (not rust)!! We need to check the PH of the water is within a suitable alkaline state, these are the general terms that apply!! We don't want too much inhibitor, which can have a negative effect on rubber seals etc!! He's on a Fernox kick back!! 😂
