Bulkhead question for return

shingo43 · 07/22/2016, 12:29 PM

Hi I purchased a used tank with 2 return holes drilled on the back of the tank, I want to hard plumb the return, and wonder what bulkhead/elbows should I use?

I believe the bulkhead size is 3/4"
if you can provide a link that will be great!

Probably measure the hole sizes first. That will determine what your bulkhead options are up front. A 1-3/4" hole is fairly standard for 1" black bulkheads.

The used tank came with flex hose plumbing but I would like to convert it to hard pvc, I wonder should I change the bulkhead for pvc because the bulkheads were both threaded.

It wouldn't hurt to change the bulkhead if you don't know how old they are, that way you know the gasket is good, and you can plumb the way you want.

Just stay away from the ABS ones. They suck. They crack and leak. I had to replace all 3 due to failure on my tank. I went with these instead:
