ABS pipe floats but PVC should sink. Strange.

If it because it is cellular core, probably.

PVC pipe and fittings come in either pressure-rated or DWV (Drain-Waste-Vent) varieties.

Pressure rated pipe and all fittings are made from solid PVC and will sink, regardless of size. DWV pipe usually has a "cellular core" of foamed plastic between layers of solid PVC (or ABS). Cellular core pipe floats, solid PVC sinks.

That explains it. Never come across any PVC that doesn't sink myself. Interesting.

Well said!!!! I bought some 4" cell core accidently--like a 10' section :irked:. I fill it with gravel and it sinks but what a bummer.

It say on it's not for pressure... And it say's Charlotte pipe.... :confused::confused:

"Not for pressure" means it is DWV pipe, that is why it floats. You can put a rock in it, or go out and buy some pressure-rated pipe.

Charlotte Pipe is the manufacturer.

I have the same issue with my 4" DWS pipe. I have used aquarium silicon to glue decent sized flat rocks to it to keep it sunken!

On a side note. The silicon usually last around six months. I had a 4" break loose from it's anchor a couple of months ago. It has become an Ornate favorite "hangout" since it started floating. It gets far more usage now that it is floating than ever before.

too short of a piece. its less dense than the water....you'll probably need like a 3 ft. piece for it to sink

Density isn't affect by amount. You can add 500ft of a piece with a density lower than water and it would still float.
Density = Weight/Volume. You increase the length of pipe, both weight and volume increase.

I put two of my floating black pipes side by side with a gap between and put a big flat rock across them. Then the rock hangs over and touches the wall of the tank, turning two caves into three or four.
