Has anyone noticed that the mains TDS has dropped. Here in Sussex.

water less dense in the summer months so tds will rise not fall, less pressure on the membrane makes the tds go up.

Why do you put your web address in most of your posts?

I find in the warmer months my RO produces pure water quicker than in winter, like Ian said its down to the density of the water as the colder the water the nearer it is to becoming a solid, when the water is thinner it can be forced through the membranes easier.
