    Reach4. Your diagram as illustrated would not pass inspection in California which follows the UPC. The WC is not vented in an approved manner. Section 905.2 allows venting to be installed in a horizontal position. However, the invert of the vent connection must be above the centerline of the...

    Help identify brand cast backwater valve

    Yes. They are available in numerous supply houses in SF. But the post by Reach4, #3 of this thread, is spot on. Why spend time and money repairing a backwater valve of poor design. Reach is referring to the Mainline backwater valve which is always open, unless a back flow situation occurs. I...

    No washing machine standpipe vent?

    Homes were plumbed that way everywhere in the 60’s and 70’. And perfectly to code at the time. The clothes washer standpipe does not need a trap or vent because it discharges indirectly into the floor drain tailpiece, upstream of the trap. It’s clearly visible in your second photo. It’s the...
