We have a 1940 Crane bathtub spout that leaks when the shower-head is on. We want to replace the spout, so we have removed it but need to remove the base adapter (correct term?) that is inside the wall. We have been unable to find the right tool that is compatible with the fitter on the old adapter. Does anyone know where we can find one?
FIXED IT. I found a better solution: heat-shrink tubing. I couldn't get gasket material to reliably adhere to the metal with epoxy, as Tim suggested.
I used heat-shrink tubing with an expanded diameter of ~1.5 inches. It's 3M brand, but I'm not sure which specific product. I used a hair dryer to shrink it because I don't have a heat gun.
FIXED IT. I can so relate to the posts here. I have the same spout in one of bathrooms in my 1939 home. It was the Cadillac of its day and local plumbing shops have breathlessly admired it - but no one could figure out what to do with it. I also saw many posts on the internet with homeowners frustrated and dreading the need to tear out a wall and replace all the associated fittings.
I tried many ideas because I too did not want to get into the wall. Plus, this is a classic fixture I would prefer to keep. My fix was so simple, but it took several attempts to get it right. I had to purchase some 1/32" thick gasket material. I picked it up from AutoZone. It is a rubberized gray material. I cut a gasket to fit on the BACKSIDE of the diverter plunger. I earlier tried with 1/16" rubber gasket material, but it was too thick. I also smeared black gutter leak fix on the brass opening - this slowed down the flow but did not stop it entirely. Make sure the plunger and the brass opening are clean before applying a 2-part epoxy. I used JB Weld 5 minute epoxy. Hopefully it will last.
