Just had our mtank pumped and the outlet baffle needs to be replaced. It's a 4" 1 piece baffle.
The inlet had no baffle. Just a 3" pipe.
I want to put an inlet baffle on, and replace the outlet baffle.
Would it be a mistake to replace the 4" outlet baffle assembly, with a 3" tee and pipe?"
I can get the 3" t's and pipe, but would have to order the 1 piece 4" baffle.
Thanks for any help.
