Sump Question

[Jarbour14]

Good evening everyone!

I am building a budget sump setup for a 75 gallon tank. I found this ADHI sump at my LFS for $50, but it didn't come with bulkheads. Does anyone know where to get them and what sizes they may be? Also looking to plug the hole on the bottom with something as I will be using a hob overflow and a return pump. Any other tips would be appreciated!

p.s
it hasn't been cleaned since purchasing so don't mind that

Thanks.

You can get lifeguard bulkheads on Amazon for a reasonable price.

They are probably either 3/4 or 1”. You would have to measure the opening to confirm.

Hard to assume scale, what do the holes measure size wise? If I were to guess I'd say they were 1 1/2 bulkheads but I'm just spit firing here. The raw hole sizes will tell you what the standard bulkheads are. As for plugging the bottom one, you'd determine the bulkhead size then install one and a piece of pipe and a plug. That part is simple. Endless suppliers for ABS bulkheads, I tend to go to BRS but there's many other suppliers if you have preferences.

I measured the holes, looks like 3 are 1 3/4 and 1 of them is 1 1/2, is that the exact size bulkheads i need?

Kinda surprising on the 1 1/2 measurement, here's a chart that's really solid no matter what bulkhead brand you wanna use. I wonder if that smallest was for previously...
