My braid loop manifold works well. In an effort to chase higher efficiency I tried a variety of manifolds, copper, PVC and straight braid (want to try false bottom next). Had a problem with straight braid, if the tap was fully opened the braid collapsed stopping the lauter. Am now back to a loop of braid connected to a T connector, high flow does not seem to collapse it, guess it must be related to lower pressure due to the two outlets connected to the braid.
