PVC

[Munch]

I'm trying to replace PVC on a plumbed tank, and cannot take it apart to check.

If the outer diameter of my PVC is 40.37 mm, that equates to 1.5748 inches.

Would that mean the PVC is 1 1/4"? or 1 1/2"?

Or no way to tell?

It's Blue PVC, dunno if it's SCH 40 or 80.

id say its 1 1/2" although i could be wrong.. no clue about blue pvc...

 

[amonchak]

Either 1-1/4" or 1" I'd guess. I have not ever seen the blue in the smaller dimeter like that. From what I have seen blue pvc in pressure rated pipe is 4" or larger. Who is the manufacturer of the pipe? Is is pressure rated pipe or possibly a pvc conduit (likely not presure rated).

Here is a reference to piping OD's and ID's for Sch 40 and 80 pvc. http://www.engineeringtoolbox.com/pvc-cpvc-pipes-dimensions-d_795.html

Pics Brah!!

 

[amonchak]

Maybe PEX pipe which is an HDPE rather than PVC. Nibco is a manufacturer of PEX and they make a 1-1/4" blue pipe.

I've never seen or heard of blue PVC either.

Maybe it's this stuff? 1-1/4" inside diameter has an outside diameter equal to what you measured.

Re: PVC

We use cpvc at work, 1.5" is the closest to your measurement

Edit: found the manufacturer, jm eagle. It's def 1.5"

I present the blue PVC -

I was hoping to get rid of the flex line, and extend...

Are u sure??? With an OD of just over 1.5" the nominal PVC size is typically larger than that see the second post reference.

Re: PVC

Either I'm wrong, or the outside diameter got inputted wrong into the software.....roh roh
Edit: I'm wrong, http://jmeagle.com/pdfs/2008 Submittal Data Sheets/Solvent Weld.pdf seems closer to 1.25"

 

[amonchak]

Bingo I agree!!! Typically CPVC and PVC have the same dimensions in the smaller piping.

 

[amonchak]

Munch are these on the pump return line of the drain or both? Did you install these or can you replace with a different bulkhead so you can use standard PVC to replumb??

 

[Munch]

It's the drain - larger on the left, and return - smaller on the right.

I can replace the bulkheads, but that'll be my next issue. What size to order.

I think in the next week or two, I'll pull these, and measure, figure out what size holes are in the glass, and replace it all. I can re-install them, and then have the measurements to order what I need.

I was hoping to order this week with the BRS stuff, but I can wait til the next one

Re: PVC

Are those the lines from Eric? He prob knows what size they are if so. After all he is a tank design consultant
Let me know if you need his number again.

 

[Munch]

Nope, these are from Cadlights in California. Notorious for bad customer service, I've already emailed them asking what they use, and of course gotten no reply.

Nice tanks, crappy service.

 

[amonchak]

If you look at the BRS bulkheads information they will show what size hole works with what bulkhead (dimension C). http://www.bulkreefsupply.com/bulkhead-abs-slip-x-slip-2.html

I think you could use some of the compression type fittings and use the piping you have now, but if I was going to do it I'd order the right bulkheads and plumb using sch 40 PVC so that new parts and any future changes are easy. IMO the compression fittings wouldn't be an issue on the drain but on the return line I'd be nervous of a leak.

Let me know if I can help ya out. I am close to Parker!!

 

[Munch]

Cool thanks! I was about to ask what size bulkheads go with what openings, but then I found that info on BRS

 

[amonchak]

Typically the nominal dimension of the the bulkhead is the same as the PVC size that matches it. IE 1" bulkhead = 1" PVC.

Re: PVC

To further complicate things, there's metric and imperial bulkheads.

 

[Munch]

Is PVC measured ID or OD?
