QUOTE(OlgaC4 @ Dec 27 2022, 01:43 PM) Not sure but pls re-check. For shower always fresh water from meter. For WC and other things using OT. Kicthen and washing machine all fresh water from meter. It is an old house; I plan not to run whole new piping. So, trying to retrofit so both T2 and T3 will have water. The pump must be after the OT.  Nevertheless, I have already finished installing the pump based on the diagram shown. Now facing pump running on/off every minute, already check no leaking and now suspecting the pressure in the pipe issue. If it is a pressure issue is there a way to overcome this? |
