My well has a 50 micron Spindown filter to a 10" KL tank and then to Carbon. I was suspecting the KL was not getting a full backwash since I have 77 degree well water. So I tried a BW with the DLFC removed (it had a 7gpm). Seemed to blow a decent amount of sediment out and did not lose media. So I left it that way. That was about a month ago.
Prior to doing this my Spindown collected a bit of visible sediment (maybe a 1/2 teaspoon per month) When I removed the DLFC, I decided to give the spindown a good cleaning. I noticed the stainless screen was a bit hard to blow air through, so I soaked it in phosphoric acid. Lots of silt was dissolved and was shiny clean again. A quick blow through it confirmed it was clear. Also I discovered that I can use the light on my iphone to shine through it to check it in the future.
Now my KL is doing a nightly 12.5 gallon per minute backwash for 10 minutes. This is significantly more flow than my well ever provided in the past. Even my hose bibs dont seem to flow that much. (I use those accordian hoses)
Fast forward to today, 30 days later, my Spindown still looks clean.. so I ask, did this actually clear my well point? or is my spindown not working?
