When we fill our system, hot water heater and all lines the system presurres up and runs good, but pump is extremely noisey and some knocking occasionally in the walls when turning off. Trying to conserve water and holding tank space it only runs 2 to 10 seconds depending on what we are doing.
The other day I was draining holding tanks and wanted to flush the grey water tank so I left the pump run an extended period. About half way through the process (10 min)the pump quieted down to just a hum maintained full pressure and stream similar to our last trailer. Could it be air i am just not getting out when first filling up the system? I sure dont want to run 10 minutes of fresh water into an empty holding tank before we start out just to get the pump to quiet down.
Thanks for any suggestions.
