Do you have any idea of what would be causing this?

It sounds like someone installed a recirculating pump meant for a hydronic heating system instead of one that is intended for potable water use. The pumps used on the hydronic systems look the same & are cheaper, but they do not have the stainless steel recirculating blades & as you have found out, will leave a rusty residue in the water. You will need to swap out the recirculating pump.
