I ordered an overflow and return kit from Glass Holes. Everything except for the bulkheads is very nice quality. The bulkheads are made by Spears but they don't inspire me with confidence. The threads look like they were machined twice and the seams from the plastic molds are noticeably off.
Is this normal for Spears bulkheads? Is there a better brand I should get? The only other brand that seems to be locally available is the Lifegard Aquatics bulkheads. Are they good? Better than Spears?
