Water pump not drawing water


Recommended Posts

Water pump doesn’t draw from exterior source through boondocking inlet (bucket w/bleach water solution to sanitize system) with valves in boondocking configuration (per instructions) or from fresh tank. Tried priming pump & still no draw. Pump is running but not drawing. Suggestions welcome.

When this happened to me, I had a loose connection between the source (your bleach bucket) and the pump such that it was drawing air in and cavitating.

Are the connections on either end of the inlet hose that attaches to the pump tight? If either of those is drawing air, you could get those symptoms. Also check that the strainer bowl on the pump is screwed on tight (and that it isn't cracked) - this is the clear plastic "bowl" with a metal strainer on the inlet side of the pump. Any air getting in on the inlet side via these spots could prevent the pump from drawing water from either the boondock port or the fresh tank.

Another thought is to remove the inlet hose and inspect to see if it's filled with plastic shavings, which seems to happen on a fair number of Olivers. With sufficient blockage, it may be able to prevent the pump from drawing in water from the tank or boondock port.

I've never use our trailer where we got water this way thru the pump, I thought you had to turn a valve under the bed compartment to let this system work correctly. Not sure if this is correct or not, let me know what is the correct way of doing this.

I've struggled with mine a few times too and found that raising the bottom of the bucket and lines above the inlet, as if you were going to siphon into the trailer, helps a lot.

Make sure that your valves - located near the water pump - are in the "boondocking position" if you want to draw water into you fresh water tank or in the "winterization position" if you just want to draw anti-freeze into your plumbing lines without drawing it into the fresh water tank.  Then attach a short length ( 2 to 3 feet) of garden hose to the port located at the rear passenger/curb side of the Oliver.  Place the hose into the liquid, go inside and turn on the water pump.

This should then draw the liquid into the Ollie.  Observe the level of the liquid going down and turn off the water pump when you are drawing air versus liquid.

After you are finished drawing the liquid into the Ollie simply put your valves into the "normal position".

p.s.  if you are unsure what valve position is right for your camper then refer to the Oliver University for a chart that shows the valve configurations for your year/model of camper.

I was also warned not to draw antifreeze into the on-demand waterheater.... and that involves the same valve settings. 

That is correct always bypass the Truma when winterizing. I also bypass the Truma when I sanitize my fresh water tank and plumbing system.
