You may want to change that 6" galvanized nipple to (2) 3/4 CPVC Male adapters with a short piece of pipe between them. Galvanized pipe will
rust over time where plastic CPVC will not. I work in the HVAC field and have seen many water heaters tied in with galvanized pipe and it's corroded with rust inside the pipe. Same goes for galvanized trash cans. Must importantly that nipple is after the filter now so there's nothing to keep the rust out of your drinking water.
