Bulkheads : PVC or ABS?

[ed99]

It's probably ABS- mine were.

If you need to glue one to the other ,you can use ''transition glue''.You might have to go to a plumbing supply place .

You can get PVC to ABS glue at Home Depot or Rona. It's next to the PVC glue and primer.

Black is usually ABS white and Grey are PVC

If it is ABS they are not rated for potable water, you should be using PVC fittings for aquariums.

weird- Albert, care the chime in?

ABS fittings can be used in aquariums. they are not rated for potable water applications because most ABS is cell cast and is not designed to withstand the high pressures used in potable water applications (sched.40, sched.80 etc...). Our aquariums don't acheive those kind of pressures however.

Very true, but as a general rule this holds true.
