Any chance someone out there knows where I can buy repair and replacement parts for this system? Thanks! R

Hey everyone.... New to me pool startup and I am having a hard time with identifying this inground filtration system... It has the filter system as well as the pump in a pit at the deep end of the pool. From the skimmer it dumps the pool water into a system of 2 strainer baskets and then into these filtration "bags". The cover of this pit sits flush with the ground and comes in 2 pieces. I could send pics if this helps... What is it and where can I get parts? Thanks everyone!! Ronnie
