What sizes and part do i need for a overflow, return pump, etc piping parts?
My company is selling lots of stuff and im planning on buying some parts for my next build, no experience with a tank with a sump and overflow, thats why im asking?
I know i need couple check valves, 90s, 45s etc, but whats the most common sizes, 1”, 3/4”?
Any advice guys
Im planing to buy a tank around 75 gallons.
Thanks for reading
