Hey all, I am stumped. My pool is filterining and returning just fine, but when i switch to backwash, I have no pressure. I have replaced the multiport valve, as well as the laterals. Still, no pressure to backwash. HELP!!

Welcome to TFP! 
Can you post some pics of the filter and equipment pad? Maybe that will help.

After you've replaced the multipaort valve and laterals, this isn't much left to a sand filter!
Is it possible the drain line is obstructed?

Are you getting flow? A gauge may show 0 in backwash. The pressure reading is indicating how hard it is to shove the water through the filter and the rest of the plumbing. Don't have that restriction in backwash.
