Grey PVC

[mark]

Wondering if grey PVC schedule 40 conduit is suitable for plumbing tanks.

The guy in the plumbing section of the local box store says it's perfectly okay for potable water, but I've been burned by their experts before.

I doubt it would leech anything into the water, im sure it would be fine, but I'd wait for someone else to chime in.

White PVC is available at Rona, I know HD doesnt carry it.

Grey pvc is often used in aquaria - simple reason, it's often a correct fit to powerheads and other components (skimmers etc) making for easier DIY'ing.

My local Home despots carries pvc, flex and cpvc (all in different areas of course).

ive used it before with no problems that i knew about.

Would I use the grey PVC fittings or the white sch40?

go all grey, the biggest reason for sch40 and 80 is pressure aplications.. for all intensive purposes we don't have pressure aplications that require sch 40 or 80.. also the inside diamiter of the Grey should be larger which will reduce the back pressure alowing more flow for the same size pipe.
