Yep. Had the other version with the screw in adapters installed and ready to plumbed to my sump and never could seem to get them tightened down enough against the washers. So put the breaks on and ordered the metric to standard and used about 5 wraps of the pink tape. Seems pretty tight/secure and sealed.@Brent Behringer looks like you went with the metric to standard conversion unions for the downpipes instead of the Broadfield method. That’s what I’m planning to do and what do you think of it?
