Came out today to diagnose issue at location, I found that the sprayers where working properly on cold on each sprayer. Once the hot side was turned on we had issues with getting the hot water to supply to each sprayer which points to the fact that it’s a cartridge issue. D155000BT shower valve type brand unable to remove cartridge at the moment. MGPNOTES: will need to order cartridge for replacement danze brand may have lifetime warranty on parts.
