I saw someone expressing frustration on a Reddit post at the difficulty they had in getting their large sediment filter to stay centered so they could properly install it and made this centering ring to hopefully alleviate that difficulty.

All the heavy rains on the US East coast loaded my whole home water filter up with sediment. I designed this tool to clean that sediment out instead of spending almost $1,000 on a year old filter that's rated for 5 years.
