Bulkhead Question

[frieseb]

I have a 1.5 inch hole and the bulkhead is 1.25 thus leaving a .25 difference. This is for a 3/4 return. I really don't like the .25 difference but I don't know what else to do. Any suggestions? TIA

Just do what this guy did:

But seriously, a pic of the size difference might help

If I am reading your numbers correctly, that means that when the bulkhead is centered in the hole, you will have 1/16" gap around the circumference of the bulkhead. It will be fine - in fact, IMO, a little bit of wiggle room is a good idea.

I agree with billdogg, you need a little wiggle room. As an example, Bulk Reef Supply suggests using a 45mm hole saw for a bulkhead 42mm/1.65" in diameter. The difference of 3mm is almost 1/8"

Sounds fine to me, also sounds like you have a regular sched 40 bulkhead. If it bugs you that much look into a sched 80 bulkhead diameter to see if it fits better.

Yes.

Buy the correct bulkhead. Or drill the correct hole.

Ok, thanks for the info. I'm not going to worry about it.
