Want to discharge my washing machine through the opening of cleanout plug of cast iron vertical soil pipe at my basement.
Size of plug is 2"7/8.
Please show me how to adapt the PVC pipe(2'' pipe) to the cast iron soil pipe. Thanks

That plug is probably 3".... I assume the w/m will be positioned in close proximity of the clean out....
1. Remove the clean out plug
2. Take 3" PVC male adapter, put teflon tape on threads, screw it in place of the plug
3. Take 3" x 2" PVC bushing and glue it into the male adapter
4. Cut short piece of PVC pipe and glue it inside the bushing
5. Glue 2" PVC trap onto this short piece of pipe
6. Cut no less than 30" of 2" PVC stand pipe and glue it into the P-trap
... and you are ready to go
Hello Hoive...
Milo started this well... but left out that you will also need a VENT for this washing machine. An air admittance valve (AAV)can act as the vent for this or you can continue the vent and connect into other vent in the basement or upstairs in attic.
I would recommend that you pipe this as I have drawn below... The AAV screws into a female adapter. I would also figure a way to hang all this properly.
You will need:
Can of cement
Can of primer
Teflon tape or pipe dope (for threaded fittings)
1-3" male adapter
1-3"x2" wye
1-3" end cleanout with plug
1-2" 45 degree fitting
1-2" sanitary tee fitting
1-2" ptrap with cleanout
1-2"x1.5" reducing coupling
1-1.5" end cleanout without plug
1-1.5" Provent (AAV)
10 feet 2" pipe, and some
Perforated strap hanging.
Let us know if need more info. Here... ;)
PS... if cleanout not 3" but 2" plug just reduce 3" stuff to 2"
MARK
.
Mass plumber, (Mark) nailed it in my estimation. The only thing I would change is the height of the stand pupe. We make our washer stand pipes a minimum of 36" and even add a "surge pipe", (see image)if needed. Good luck, Tom
Mark, yep, I was thinking whether I should suggest vent in or not. But then I didn't suggest it since the trap would be only few inches away from the main 3" stack. I thought absence of vent in this situation would not inhibit flow over few inches of horizontal run.

Anyway, just so Hoive is clear... if there are no fixtures connected into the stack ABOVE the connection of this plug then you don't need a vent. BUT if you have fixtures above it like I think you do (or cleanout would not be there) then you definitely need a provent or an individual vent off this washing machine drain as anything that passes the washer connection/trap could siphon trap of water and allow sewer gasses into home if no vent to allow air into system.
Hope that made sense?
Good luck!

If I tied horizontally into a vertical stack with a C/O tee and a male adapter, my inspectors would sh** lil' green nickels, and rightfully so.
Irony of ironies, I've been dealing with this very scenario on my most recent job -- We need to tie a grease interceptor into a 4" vertical stack, but the lowest fitting was a 4" C/O tee.
Anyhow, this last Friday, we cut into a live stack in the middle of the afternoon and replaced the C/O tee with a Sanitary Tee -- No Brown Trout, but we were prepared for all contingencies before cutting into the stack.
Hoiveplumbing: you don't use PipeDope on PVC . It contains acid that will soften PVC threads eventually producing leak. If you still want to use paste-like thread sealer you will have to buy one that is made specifically for PVC and other plastic pipes. These sealants are not so common and very seldom sale in BigBoxStores. Otherwise, Teflon tape is the choice.
Growler...
You know I won't argue with you here... It is also illegal to tie into cleanout like this in my area... exactly why I had hoive at least install another cleanout in end of run.
I'm glad you posted this as I should have posted that for Hoiveplumbing so he could make the decision...
Hoive, if you want... you can cut a new fitting into the stack... it really is best in the long run as tying into cleanout is code illegal and a home inspector could raise a flag over it when you try to sell your home. We are glad to help if interested in this... let me know.
Otherwise, proceed as diagrammed... system will work fine in this case!
And nothing like cutting into a live stack... huh IAG... can be very messy! Always a pleasure to see you here Growler!. :)
MARK
Still, he's going to lose a full size cleanout if he plumbs it as drawn.Quote:

Just a thought.
Milop, Growler!
Adding a surge pipe to a washer stand pipe, (see image) can get me busted?Quote:

Thanks for adding one more item to the many restrictions of UPC that I find both, costly, silly, and in some cases downright stupid. What's the reasoning behind this oine? Aren't the rest of the 90% of us glad we don't follow UPS? Have a great day! Tom
Tom, geeee, get over it!. and stop scaring people with your pictures this early in the morning !:D:D:D
Can't get over it Milo as long as you and Growler keep bringingt UPC into your answers.Quote:
