Some are thermostatic, most are pressure-based. Those that are thermostatic tend to fail-cold. Those that are pressure-based can fail either way, or altogether. Generally, one must replace the cartridge - that is the internal part that does the mixing - to fix either. In hard-water or high particulate (sediment) situations, failures are quite common and can be very annoying. > Peter Wieck > Melrose Park, PA I'm pretty sure this is a 2004 thread risen from the dead. But anyway, I haven't seen a thermostatic one though they probably exist. All the ones I've seen in a large campus setting has been pressure based but the limit was a mechanical stop that couldn't be adjusted. What we found when we had a lot of complaints, particularly in group shower rooms like at a gym or old dormitory, is that the pressure from hot and cold water supply had to be within pretty tight constraints or these did not work. There was nothing wrong with the valve, but if it got more than maybe 5 pounds pressure on either it got strange results. And that can happen pretty easily with large usage upstream. |
