You should consider replacing the manifold if you notice cracks, warping, or brittle plastic, which can allow DE powder to bypass the filter and return to your pool. If you see DE powder blowing back into the pool after a backwash or cleaning, the manifold is often the culprit.

This product includes the bottom manifold assembly itself. It does not typically include additional hardware like O-rings or fasteners, so you should inspect your existing hardware to see if it needs to be reused or replaced separately.
