Water viscosity - don't give me that bollocks.
We're pumping water water through hose-pipes, not trying to ensure fat gits veins are kept free of cholesterol.
when i was cold water only i used to have to turn my pump up to near max to get a decent flow at the jets during the cold winter months,with hot water i dont have to,its gushing out on 45 on my controller.....
When I’m able to see the difference in water viscosity I’ll believe you Daz, like you can with honey. Until that point I cant say I’ve ever seen water behave as if its gloopy or thickened, especially because of the temperature.
Youre doing your regular thing chap, trying to justify your life’s decisions to others so you can convince yourself.
