Warren Webster traps

Options
A contractor came into our store looking for repair capsules to rebuild these W.W. traps. There are about 2 dozen convectors in a church with these traps. Our supply sources have been unable to make a positive I.D. on the trap model. As you can see from the 1st picture the odd design of these traps makes it much easier to repair than replace. Does anybody know for sure what the model number is ? Thanks.

    That looks like the WW 02 series. The Barnes & Jones #1972 cage unit should fit as well as a Tunstall TFWW-2501.

    I'd get that cap off with a 1-3/16" socket and use a 7/8" socket to remove the seat.
    In order to re-use the cap, the old element needs to be removed. sometimes they spin out, often they need to be dug out.

    Right. If that is a #7-series trap, there will be something on the side of the body such as 702, 712 etc.

    But the shape of the body looks like a plain 02 trap. The 02 superseded the 5 and 7 series traps, I believe sometime in the 1930s. When Webster came out with their convectors ("Webster System Radiation") again in the 1930s or so, they would have used their current-model trap which was the 02 series.

    Confirmed- that is an 02-series trap. I dug up an 02H that we had sitting around, and the cap does have those little sevens on it.

    The sevens probably refer to the disc-type element originally used in this trap, which is a smaller version of the earlier 7-series disc-type element. The 5-series traps had "Sylphon" bellows-type elements.

    So the B&J 1972 or the Tunstall TFWW-2501would be the right part to repair this trap.

    We are thinking it's a WW 702V-1

    Either way the cage unit part number is a 1972. Let me know if you need to find a distributor to your area.
