We have a DEL 60 that just developed a leak in the lower tank. I know this has been discontinued in favor of the DEV, but the DEV requires a replumbing (and new backwash valve) per Zodiac since the connections are different

So I was curious if anyone knew a place that still had stock of DEL parts that might have a lower tank (part number R0358600) that I could just "screw" in in place of the existing one. I live in the Dallas area

Thanks
