Air in water on new Rpod 195 - Event Date: 27 Jun 2020

I hope someone can assist, please!! I have air in the wTer line continuously despite that I have purged Rpod 195 (2020) water system several times with all water valves open. Also opened low point drain. And while pump runs it burps sir too. Flows naturally when pump is off. Bled hot water heater until water flowed from unit. Filled fresh water tank several times and let furthest tap open with pump on and still get bursts of air the water even with in all faucet taps open. This is a new rig so water pump was not ever working normally to my knowledge. (always had air in the lines)   I have located pump and all SEEMS to be in order but clamps are crimp on vs screw tightening and I HAVE NOT located valves for hot water bypass ( that is used for winterizing) only the 1 valve at pump used to divert water from pump to loose hose to pull in antifreeze.   So any info how to get air out of line or trouble shoot why air is getting into line would be so appreciated. Thx in advance. Would love to be able access the H2O in this new fancy new rig!!

Hi Stephen. Thx for your reply. 1   I filled fresh water tank completely till overflowing. 2. I’m relying on water from tank not city water so pump is on 3. I can only locate the valve on water pump (accessed in front storage area opposite side of outdoor stove through kick out held by 4 screws) where I checked   the valve switch and it’s correct and in full position located between pump and suction hose to pull in anti freeze. But although I know where hot water heater is and that 1 valve I can not locate the 2 other valves to see if they are fully engaged in correct position. The hot water heater is at back of rig but no access to the hoses thT I can see   Any clue where to find them in my model.? Good idea to check those valves. Just gotta find them! Not much online yet about this model as it’s a new Rpod -195 model. 2020 year.

Ok so I have found all 3 shutoff / bypass valves in Rpod 2020. For the pump Valve enter via outside storage door and remove panel on right held by 4 screws. . For shutoff valves for water heater enter by vacuum cleaner. Yes you heard this right. It is ridiculous! But there is a small 4x4 panel held by 4 screws   Inside there are 2 valves. On function is the Handel inline with hoses which is what you want when hot water is in use. Off is perpendicular to hoses which is where you want them after system is drained and before you put in antifreeze to winterize rv.    Now to figure why water pump grabs air all the time

I've run my "self priming pump" 15 minutes without water flow. Finally used my antifreeze line to prime the pump and away it went. Nothing was bad, it just didn't self prime.

Is the hot water tank full?? If the hot water tank is not completely filled, you will get air until you finally draw enough water into the tank.
