OATEY 43924 – Frequently Asked Questions

1) What is the Oatey 43924 3 in. PVC flapper for, and does it come with the seal?
It's the replacement flapper for a 3 inch PVC backwater valve, and the O ring seal ships with it. The flapper is the internal gate that seals closed when the line isn't flowing and swings open when waste passes, so if a valve is passing sewage back or won't seat, this is the wear part you replace rather than the whole valve body.
2) Can I get to the flapper to replace it without digging up the backwater valve?
Yes, on a valve fitted with the threaded access cover. That cover is what the valve provides for reaching the flapper, and where an access sleeve has been run up to grade using Sch. 40 pipe, the swap is done from the cleanout without cutting the buried body.
3) Will the Oatey 43924 flapper fit a 3 inch ABS backwater valve, or only PVC?
The flapper itself is molded PVC, and it's sized to the 3 inch valve. Oatey builds these backwater valves in both PVC and ABS bodies, so match the part to the valve size and body you have on site. The solvent weld joint is the valve body to the pipe, not the flapper, so the flapper is a drop-in service part either way the body was cemented in.
4) Is there any glue or cement needed to install a 3 inch backwater valve flapper?
No cement. The flapper drops into the valve body and the O ring does the sealing, so it goes in dry through the access cover. Solvent welding only applies to the valve body where it joins the drain line, which stays in place during a flapper swap.
