Almost done with the build..
I have a very long (150'+) 2 inch PVC pipe that is connected to the backwash on the DE filter. It goes all around the house and to the front - where I will be draining it to the sewer cleanout via a short 'blue' hose.
My PB mentioned that this long backwash pipe will actually cause me problems because there will be pressure 'loss' and backwash will not be that effective. He says that max of 10 to 15 feet of backwash pipe is most effective.
I am not sure how the length of the backwash pipe will affect backwash performance... thoughts?
