Shower fixture replacement in a BF10.4E
I have complained about the poor quality of RV shower fixtures and also the weather. I can't do anything about the weather, but I did replace my shower fixture. The factory installed the standard P...

Thanks. Mixer is here at Defender. It is listed at $112 but they only charged me $97. Note that this model has a BSP outlet to the bulkhead sprayer hose fitting. The bulkhead fitting matching that is this one from Fisheries Supply at $35. Defender does not seem to list this one though I bet you could call them and get it (I like and recommend Defender - they are usually cost competitive and the customer service is good). Alternatively, do a Google search for "Scandvik 990047" (the mixer) and "Scandvik 10007" (the bulkhead elbow) to find many sources. The Scandvik link in the original post will get you to their catalog, there are many choices besides the one I used. Ambassador Marine is an other quality brand. The advantage of the parts I used is they will plug the existing holes for the Phoenix mixer.
You will need a BSP coupling to connect the bulkhead elbow to the mixer outlet hose as they are both male thread. I got one from McMaster-Carr - you won't find them at Home Depot! - it is pn. 4860K676 on the referenced page, a 3/8 BSPP coupling. The coupling requires a gasket which is supplied with the bulkhead elbow, these are parallel threads and not self-sealing. A standard sprayer hose will fit the elbow outlet as it is 1/2 NPS.
These hassles are because all of this marine stuff is imported from Europe, where British Standard thread is much more common than NPT. Whatever you order, take a close look at the specified inlet/outlet threads to be sure you have the right one or the right adapters. The above mentioned parts will work together, with the caveat that the hot and cold inlet is going to be a female 1/2 NPS. It will screw onto a 1/2 NPT and probably work (that's what a lot of people do) but it is not as secure as true 1/2 NPS. Most RV fixture inlets are 1/2 NPS, the straight thread is required so that the securing nuts can be run up against the bottom of the counter etc. So you could cut the tails off the old fixture and use those (though they are plastic). I machined some out of stainless on the CNC lathe, but I think a "real" plumbing store would have the right nipples.
Oh, the sprayer is this one. I have this one in the boat, very nice solid brass, but as I said a potential chip hazard if you drop it. Also it does not lock on, have to hold the push button.
