Went to the lfs today. Asked them best way to plumb my sterilizer. They told me to plumb it into my existing plumbing into the pipes flowing water into my sump. It wasy understanding that it should be into my return pipes or a separate pump from my DT and back into my DT. What's the best way to plumb it into my existing plumbing. The return or the drain pipes that puts water into my sump. Or a separate pump from DT to tank?
