Is there a minimum/maximum GPM requirement for backwashing a Quad DE 80? It has a 2" slide valve on it and I was thinking of backwashing it for 3 minutes at maybe 30 GPM or so. Any recommendations?
I've looked in the filter manual and couldn't find any mention of it. But I've heard that there's a possibility of blowing out the cartridges when plumbing the Quad DE backwards(output/input are opposite on a Quad DE vs. a regular DE filter). But wouldn't backwashing the filter have the same effect on the cartridges as plumbing it backwards?
