I'm getting ready to plumb in my solar panels to my equipment pad and I'd LIKE to mount the controls and piping ABOVE the sand filter, on the brick wall of my house. I'm trying to save space and keep all the controls handy. It sticks out quite a ways, though (2" plumbing), and I'm afraid it will be in the way of servicing the sand filter when needed. So, how far above the filter should I mount it, or is this a bad idea?
