2902ws water system issues...
Ok, maiden voyage in our new 2902ws....all seemed ok when sanitizing and flushing the FWT and lines but I noticed on the 2nd camping day that the pump continued to run. The system was pressurized but lower than usual and you couldnít hear the pump running in the trailer. Checked via the access door and noticed the filter housing ( with the new filter in it that I put in right before we left) was partially full and the pump was running with a quiet hum.
First order of business was to shut it off under fear of water leaking badly some where. Nope. All good every where. Pulled the filter in case it was bad, reinstalled the housing without the filter and tried again. Sometimes it would shut off fully while others it would keep the low hum. Seems to be completely random.
I can see air in the inlet pump strainer and in the clear housing when the pump is running which explained while we were getting air each time we used it. I figure I have a loose connection so that is my next investigation. We just let the pump pressurize the system until we couldnít hear it (took a while longer than it should due to the air in the lines) and then turned the switch off. We turned it on when we needed to use that water. Very manageable. Note: even when turning on the pump the next morning it wouldnít run....there wasnít sufficient loss of pressure/leaking. I also checked the winterizing valve was in the correct orientation which I never changed but did cycle it when checking this issue.
1. Would air in the pump cause the continuous (low hum/vibration) pump operation?
2. Should we have opened the water miser at the shower when priming the system (we didnít use the shower).
3. Does anyone know why there appear to be two lines that join up before the pump inlet line just before the valve for winterizing?
