I'm in the middle of moving my sump from beneath the tank to the basement. I have an external return pump (Iwaki 100RT) that will be at the front edge of a counter near a support 4x4. The 4x4 supports a beam crossing the floor joists above in support of the tank and has been there since tank was set up in 2004. Output will go through a true union ball valve to an elbow then will go over the sump to the back of the counter; and then up the wall, to the right a few feet, through the floor back to the tank. I will use support clamps at the wall. Should I also use a support clamp after the ball valve using the 4x4? Is it safe to have a support clamp there so close to the pump outlet given the likely vibrations? I was going to add the elbow directly after the ball valve, but would it be better to use a short piece of 1" pipe between the two?
