I have a cracked bonnet nut on a Wolverine Brass two handled shower faucet, looked for a model and all I could find was a 44 stamped on the bonnet, along with WV which I assume is wolverine brass. The crack runs the perimenter of the bonnet just past the threaded nut part and causes the handle to slip. I don't know how old the unit is since we've only had the house about 5 years, but the stem is made of a grey plastic so I assume it's not ancient. I cannot seem to find a replacement bonnet anywhere. The bonnet probably can't be welded, but I was wondering about epoxy. Do we have to give up and replace the whole assembly? I've heard WB won't sell parts if you're not a licensed plumber. This assembly is in a funky concrete shower in our basement and I don't want to throw any more money into it than I have to.
