After reading about the pump failures in another area of this forum, I too have hard well water with a lot of iron content. I have a 50% antifreeze mix and the water mix seems "slippery" to the touch and more viscous than tap water. I wonder if the mix helps lubricate the pump rotor. I have notice fine brown particles in my test samples and I have been thinking about adding a filter I just don't want it degrade the pumps performance.
I have a few questions about cartridge filters.
What brand are people using?
Do they restrict the flow?
How do they hold up to the high temps?
thanks in advance
