Trying to cap a water line that connects to my sewage out line. I purchased a cleanout adapter with cap in 2" and 3" and one is too big and one is too small. I think I need a 2-1/2" connector.

NOWHERE in my local brick-and-mortar stores can I find this size, which leads me to believe...

  1. I am measuring incorrectly, or
  2. The builder used some off-the-wall size and that is why I am having such a pain time to find the correct cap

To use the convertor coupler, is this the right size I'd need? (tried to block out the local box store as I wasn't certain if that was permitted to post)

If you can't find a 2-1/2" cleanout adapter, but can find a 2", then consider this option instead:

Depending on your local suppliers, you might be able to find a cleanout adapter which will fit directly into the end of the reducer coupling, which then makes the 6" stub of 2" pipe unnecessary.

My (layman's) interpretation of the IPC - 708.7 Minimum Size rule for cleanouts is that Exception 1 probably applies:

stack cleanouts that are not more than one pipe diameter smaller than the drain served, shall be permitted

  • Home depot is closest to me...is this the right size? https://www.homedepot.com/p/Charlotte-Pipe-1-1-2-in-x-2-in-PVC-DWV-Hub-x-Hub-Increaser-Reducer-Coupling-PVC001020600HD/203391373 – Stanley Jones Mar 16 '22 at 18:27
  • No, that's a 1-1/2" x 2" - you need a 2-1/2" x 2" (although that listing is a bit weird and difficult to make sense of). And (lol) now that I'm looking, it seems like that reducer is about as scarce as the 2-1/2" cleanout adapter is ... You might just be better off ordering the 1-1/2" adapter online :P – brhans Mar 16 '22 at 18:38
  • haha - it is insanely scarce! I can't find it anywhere! I think i'm just going to purchase the first two images you posted above so I get the right things. I've already got the pvc cement as well as the cleanout adapter with plug. I don't have 6'' to spare, I assume it would work all the same if I cut the 6'' pipe down to about 2'' - 3'' ? – Stanley Jones Mar 16 '22 at 18:39
  • You could also go **up** to 3" for the cleanout. And you can get cleanout adapters that glue straight into a hub, with no intervening pipe needed. – Ecnerwal Mar 17 '22 at 14:48

If you have both sizes in hand and neither fits the pipe, then it's not an issue of measuring...

You don't indicate what brick and mortar stores you've looked at. I'm presuming you when to the local big-box retailers. Try an actual plumbing supply house instead. I'm pretty sure they'll have exactly what you're looking for. Bring them a pic of a tape measure across the pipe you're looking to put the fitting on and show it to the guy at the counter. Either he'll point you in the right direction or he'll have it pulled off the shelf in the back room before you put your phone away.

  • Unfortunately for me, even the local plumbing stores only have 2'' or 3'' -> as well as my box hardware stores – Stanley Jones Mar 16 '22 at 17:41
  • That seems unusual, @StanleyJones. I'd expect the plumbing store to be able to order what you need. Might take some time with all the supply issues right now, but that's better than not getting it at all. – FreeMan Mar 16 '22 at 17:42
  • I live out in the middle of no-where. Maybe the two places I called were just unwilling to really assist, they placed me on hold and came back a few moments later and said they do not have and can not get a 2 1/2'' – Stanley Jones Mar 16 '22 at 17:43
  • if I can find the right piece online I'll order it myself, lol – Stanley Jones Mar 16 '22 at 17:43
  • In this virus era, after my local open-to-all plumbing supply house closed its doors, I have tried to find another one within driving distance that will take my business. So far all the 5 or 6 closest to me have turned out to be "trade only" unwilling to sell to retail customers. I have had better luck online and have found a half dozen USA-based ones that seem good to me, with at least one having a warehouse in the next state over, making for speedy shipping. – Armand Mar 16 '22 at 19:10

    Well yeah, you get that with phone enquiries, if the customer didn't walk in to place the order, how likely are they to come in and and pay, especially if they find it cheaper or faster elsewhere. If you rock on up cash in hand they can probably get a special order in for you. – Jasen Mar 17 '22 at 03:35
