Inquiry (采购产品): HELP, Please I have PVC shut offs (1/2 and 3/4) in my house that the bleed screw in the side is rusting off. I need replacment screws. My plumbing supply store where I got the shut offs from 15 years ago can not supply me with replacing screws.They only say to replace the shut offs. The local hardware stores do not carry the correct size and have no interest in ordering them for me. The shut off has a large U in a circle on their sides. There is also the following marks. NSF-pw SE1/2 8118. Is this your shut off? If so can you supply me with 30 screw? If not can you tell me who made the shut off? Anything you can do for we will be a life saver!!
