Threaded Adaptor Transition

i have an old house with old cast iron drains.....where it actually connects to a trap i guess its threaded galvanized......do they make like a male threaded to PVC adapter I can use to convert the drain to PVC?

also i am gonna connect 1 sink and extend the drain to the washing machine

do i just use an elbow up and drop the washer drain hose in it?

or do they make some special thing for that?

thanx

Home Depot or Lowes will have the thread to PVC pipe for you. ALso all the fittings you need.

. No you have to get or make a P trap in the bottom of the pipe then put a riser pipe open at the top. Then just stick the washer drain hose into it.

The best that I understand what you propose dosen't have any provision for a vent, good practice indicates that you should have two vents for your hook-up, sorry for the negative.

the cast iron tee is part of the vent stack that the drain runs into

is this ok? its been like that since 1935!!


it originally went to a sink....now it will feed a slop sink and the laundry

If I'm reading this right, if the pipe leading vertical above the tee is a vent with nothing washing/dumping into it, this will suffice as properly vented but only if that vent leads to the roof either by connecting to other vents or individually through the roof.

If you have a true vent stack the only fixture connected would be at the base, if you have any fixtures connected above that point it is no longer a vent stack, you shouldn't run multiple fixtures on a branch without at LEAST one revent that connects at 6in. above the highest fixture on that line.

In 1935 it had only one fixture connected to the line, even then they wouldn't do what you propose, sorry.
