The system is an 8" stainless manifold on about a 350' diameter tank. It is elevated about 20' with 24 diffuser assemblies hanging down about 18.5 feet on a tee with 5 diffusers on the bottom. The new assembly uses 2x 3" unions on a 2' extension attached on the bottom by a 15' long diffuser assenbly, and on the top by a waffer style valve that uses a companion flange that threads into the header.
My Problem is that the diffusers use coarse threads and each one has 7 areas of coarse threads. There is alot of deflection and my fear is something will vibrate loose into a 16' deep pool of poop. Any suggestions?
Coincidently there are only 14 X 4' poles welded onto the clarifier wall the whole header manifold sways because #1 There is only support of the weight nothing to prevent sway. #2 The circular manifold has a gap at the end for the catwalk that connects to the other tank.
