Found pressure entering building at 60-65psi. Pump not working at all. Checked kitchen and had good pressure. Checked m/b lav and clogged aeratior. Cleaned and faucet works fine. Needs new pressure balancing cartridge in m/b shower. Toilet had good pressure. M/b shower is only area that is currently an issue but only hot side. Will replace cartridge as per Tim as Nate left as I got there. Danze showervalve pressure balancing cartridge corrected issue with m/b shower low pressure on hot side.
