Spring and borehole water is often acidic and copper pipe lasts months at
most. Have it tested or use only plastic parts.

What filter do you use for the iron and is it effective ?

I'd have to check. The filter medium is a granular substrate, the filter
itself is a 4 feet high cylinder filled with this stuff.

Is it effective? Well at a visual inspection level it is, beyond that I
don't know. None of the farmer's sheep have ever died!

Testing both water supplies is on the cards for this summer.
