Seems that Pex A gets a better rating than Pex B in regards to burst pressure and flexibility. Most who use Pex B are saying to upsize your pipe to the next size to get the better flow. Think i would not have put drywall up, but instead just put up some good one side plywood. The plywood would be more durable than the drywall if you get a water leak or need to remove fasteners or the manifolds. Hope you had a great time with your kids and grandkids....its will let you wind down and have some fun !!
