Our pool plumbing was done before posts were marked for patio cover due to an oversight by our builder. They've cut through new patio decking to create footers for the posts today and when they did, they cut the plumbing lines in three of four footer holes and are suggesting 45 degree bends to go around the plumbing. They've cut multiple plumbing and electrical lines today and builder says the 45 degree bends and junctions to be added will not impede pump performance or give us issues down the road. Of course, they don't warranty the plumbing. Now, the plumbing is 4 inches in diameter and pool company assures us the flow will not be impeded.
It seems to me that any 45 degree bend impedes the water flow and adds strain to the pump. Plus, plumbing will fail where the joints are located and we'll have many more now due to today's work. Hoping someone who knows more about the plumbing than we do, could provide advice. Could the pool company be correct and we're fine?
