The ASSE-1019-A in your pics is an industry standard for anti-siphon/freeze-protected and not a model number. But I don’t know where you would find the model on yours.
Ahhh – the SA inside the C means Canadian Standards Association. So looks like it’s approved for Canada. But that’s also no help for the model is it. Why do manufactures like so much mystery!
Holy Moly how did you see that? Ahh – I know. You have to rotate the picture. That just looked like some fancy schmancy design to me. Have to remember to look at different angles.
You might be able to find parts here. I believe B&K was an inexpensive import product maybe 20 years ago, but that they acquired a few American companies. It might be easier to just replace it.
We have a home with 1 shower/tub combo that has 3 valves (no pressure balancing or anti scald). When the tub is running you get full pressure and can balance the temperature just fine. When you turn on the shower though you have to turn the hot all the way on and barely have the cold water on. The shower then starts this loud fluttering noise until you turn the cold back up which gives you a cold shower or turn it back to the tub so no shower. Every other fixture gets hot water high pressure no issues. I replaced the hot cold and diverter cartridge's with OEM problem seems to be worse. Is the diverter the issue. this problem had gotten gradually worse since we bought the house 2 years ago, meaning hot water was starting to fade in shower but not this bad. I heard that it is potentially back flowing from cold to hot or that we need a spring check valve at the heater hot water pipe, air gap devices, old pipes (copper), failing water heater. arrgh. Please help get her off my back.🙄
Is these the right fittings to use on this mixing valve? [img]https://cimg1.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x1504/20211116_083910_6d4e32379edfeabdc07901531408529e3fee862d.jpg[/img]
