Hi, I set up my RO and DI a fews weeks ago and have been getting a reading of 000.
Problem is i live in a town house and the system is plumbed into the 1st floor as there no pressure on the ground and no access to mains.
I had the idea to run a pipe down into the garage to my water storage. But now my readings are at 004 at the end of the pipe and 025 at the storage tap. The tank may be dirty which would explain the change but the pipe shouldnt be.
Sorry if thats not very clear, but any help would be good.
