We were having a septic issue, and while researching online, I came across a site that sold a Washing Machine Lint Collector that mounts onto the laundry room wall. I made the purchase. Before it came in the mail, I had the septic tank pumped. I told the service guy what I had purchased, and he laughed. He said it was a waste of money, and I should send it back. What are all of your thoughts on this type of product? Is it necessary? It was not cheap, so if I don't need it, I will send it back. My tank does have an effluent filter.
