The PVC’s we’re not ‘snuggly’ fit. I had to glue them together. it will be easy To clean. I only glued the elbows and T’s, not the black PVC (it’s a screw on). It should be easy to clean.
This is my thought as well. For what it's worth, I worked at a fish hatchery for over four years. Used regular purple primer and glue for all of our fittings with no issues.
