I have gotten a little tired of it already, though. So I decided to find out for myself. I found a bad copy of a single-page handout on the plumbing fixtures, indicating that they are Delta SBS. I could find no other identification on the faucet or elsewhere. So I went online to the Delta Faucet site and tried to find that model. No such luck. I looked at the list of models and SBS was not there. Suspicious, I called Delta.
A real person came on almost immediately! That was shocking, of course. I told her what the model was and she said that the SBS models are made specifically for mobile homes. Once again I ask why? I thought we were done with that nonsense. But apparently not. I told her my question about the temperature and she said I would have to adjust the "rotational limit stop" and proceeded to tell me the steps. I had to stop her because the steps were getting a little detailed and she said I should just go do it now, while she was on the phone to tell me what to do. It requires a 1/8" allen wrench to get in. No need to shut off the water. All of the furniture I have bought lately came with allen wrenches so I had several but none fit. None were labeled either, of course. I asked her if there were a document online that spells out the steps and she hesitated and then said I could look up model 1400 because it has a similar design.
After a bit of hunting I did find the instructions I need, complete with diagram, so I figure I can do this once I have the right size wrench.
Two things bother me:
The service guy didn't seem to know about this adjustment. Shouldn't he know? He works on nothing but these homes.
The model is made for mobile homes so I can't find the instructions, price, or anything about it online. Why not? And why, given that plumbing is supposed to be the same as for a stick-built house, is it necessary to have a model for mobile homes only?
I won't dwell too long on it.
