simple question

[iamthewalrus]

if u buy a pipe and it has nsf-pw and nsf-dwv is it safe to use?

[Aaron ?????]

that dosent make any sense one is the high pressure one and the other is drainiage pipe im confused

maybe some pictures will help

[spudshot]

yes, pressure rated pipe is obviously rated for drainage too, as long as you have a pressure rating xxx-PSI on your pipe go ahead and use it

[Aaron ?????]

yea but isnt dwv the weak one for drainade and whatnot and the pw is the high pressure stuff

[spudshot]

yeah, but a pipe rated for 200 psi is obviously rated for drainage purposes, as long as it has the pressure rating you're fine

[iamthewalrus]

ok, thank u, cause i saw the dwv thing on my 4" chamber and i was like "crap", thanks captin

Like said above, if there is a PSI rating, your good (some pipe companies label things weird).

Spudshot and PCGUY nailed it on the head quite nicely. If it has a pressure rating, disregard the DWV. Of course, if you can't find a pressure rating, you might want to reconsider using it.
