How big is the block and how big is the brick?
To answer this question you should first determine how much area you want covered by the umbrella. If you have a small porch and still need sunlight on it then a large umbrella make block the necessary sun for you plants and sunning recreation. However if you have a large area to cover, the bigger the better!
because the trees cover the forest and don't allow sunlight to touch the ground
the PVC valve should be located on the valve cover by the intake manifold on top of your engine block
