PVC Question

[texhorns98]

I guess all PVC is not created equal!

I bought 1" to plumb the new tank, but I ended up with some rather thin walled stuff. Can this be used at all? Obviously, PVC is cheap, but it would save a trip.

You got yourself some thin wall PVC - works for our aquarium use just as good as the thick stuff...

It will be fine. There's little pressure on an aquarium and you're not burying it underground.

 

[kirru]

Thin or Thick, shouldnt really matter with what we use it for. Should be very little pressure on it. I'd go ahead and use it

 

[enderg60]

I prefer the thin wall stuff actually. Its like being half a size bigger when it comes to flow!

And with the pressures you get with aquarium stuff its no big deal at all.

The biggest issue is using the correct fittings with it. If you use fittings designed for thick wall you will have leaks.

Huh?
the OD is exactly the same... no?

 

[rdnelson]

I don't think so. Pipe is sized off of ID not OD. Could be wrong but it isn't like that has never happened before. LOL

depends.

you have pvc sch 20, 40, 80 which is grey. then you have the cpvc which wont fit any of the other fittings.

we mostly use sch80 fittings with sch40 pipe at work because the fittings are thicker and take more abuse

I disagree...sch. 10 or 20 is elcrap. IMO, not worth the risk.

 

[texhorns98]

No schedule listed, but I think it's 20. Seems to fit all the elbows, it that I have. Again, it's $2 if I need to use Sch. 40.

 

[rjrgroup]

I would use sch. 40 because of vibration and degradation from...well...everything. Look at it funny and it might brake. Hardly seems worth the risk over a couple bucks.

 

[rdnelson]

I agree. I would not use anything less than schedule 40. Schedule 40 fittings are fine as well but as Eagle points out, if you go schedule 8 on an valves, unions, etc they are built much better. I used schedule 40 on everything including valves.

Off to ACE it is! Thanks guys...

Nopes
pipe is sized off of OD, not ID - which is why SCH80 fittings fit SCH40 pipe...
More wall thickness, less ID

 

[rdnelson]

While you may be correct with plumbing I know for a fact that isn't correct for electrical. It is all about ID. Kind of like voting laws. hehehehehe
