I have a recently rebedded/refurbished Birm Iron Filter which expells iron and sediment after the outdoor sprinklers are ran. We had the same problem prior to rebedding. The iron filter is NOT in-line w/ the sprinklers. I have a 50 psi community well feed to the house; the iron filter T's off the main line. The main line continues on and runs out to the sprinklers.
Has anyone ever seen this? Do I need an inline check valve to the iron filter (which runs to a water softner and the rest of the house). I thought as long as I wasn't inline w/ the main line, I should be ok. After a regen cycle, there no more iron that is expelled. Is the iron filter somehow getting aggetated? We inherited the system when we bought the house.
Thanks in advance!
