I can only ever find the stuff online, and lets just say that it isnt economical for me to buy this stuff online.

Where does one purchase 1/2" PVC, and other sizes, like 3/4" 5/8" etc.
Ive checked home depot, and they dont carry any of the white pvc at all, so I haven't really bothered to go to Rona as its likely they wont carry it either (ya i know i should call)

What about using electrical conduit... Would that be acceptable for use in an aquarium environment, and/or under pressure?
 
Do you mean using 1/2" gray electrical pipe. If so Ive used it with no problems. Its just not meant for real high pressure.
 
I buy mine at Home Depot or Lowes. Never had a problem finding it at Home Depot.

The grey electrical pipe should be fine for most applications, as lonmg is it is not a high pressure one.
 
Must be a local code thing in your area. Around here every hardware and home improvement store has it.

The gray PVC electrical Non-Metallic Conduit (NMC) is different in that it has a UL stamp, and is gray due to sunlight resistance. It is as thick as Schedule 40 PVC, but as has been pointed out is not rated for carrying liquid under pressure, nor approved for potable water. It would probably work just fine, though.
 
I dont know why home depot doesnt carry it, But the last time i was there and asked, the guy literally stood there, and looked at me like I was nuts, and it would be unheard of for them to carry the stuff.

The grey PVC conduit is what I may end up using for my aquarium plumbing, since I seem to have a couple of testimonies saying that it works without issue.

As far as the pressure is concerned, I was asking because I was considering using some of the conduit fittings for my RO water tank, which will be pressurized to 80 PSI.
Obviously, this is not a good idea.
 
I wouldn't use it for 80 psi. Not sure the working pressure for it, but it seems like a lot for pvc joints to handle...I might be wrong, but I like erring on the non-flood side...lol
 
One inch Schedule 40 PVC is rated at 450 PSI. I assume the NMT would handle a good portion of that, but would hate to bet on it.
 
Why not go with PEX instead? Most places around where I live don't carry much PVC water supply pipe because it's not the best solution anymore.

PEX is flexible, has a burst strength of 160psi at 76F and is NSF rated for food and water purposes. THere are tons of fittings and such a Lowes.

Probably not as cheap as PVC, but it's more versatile. You can also hook it into a manifold system for distribution.
