Water trickles while on water pump

Were camping in our 2017 Axis 24.1 and the water pump is giving us problems. On city water were fine, but if we try using the water pump (while disconnected from city), the faucets will trickle water and barely any will go in the toilet. I checked the filter and cleaned out a little plastic debris, but not much. Also checked all the flex hose connections and theyre all clear and tight. The pump comes on and runs, but not much pressure at all. Tank has plenty of water. What else can I check?

Well I dont know for sure. But I think some of the pumps have a pressure adjustment on the top of it (little set screw on top). Look for "4 season" on you tube - seems like that guy talked about this adjustment.... perhaps your is turned down all the way.

Or the water pump is going out (or has something wrapped around the impeller preventing a good pump)?

I was going to tell you to check that filter screen but it looks like you did already. Perhaps you have a ton of debris in the feed line/tank inlet blocking it? Can you blow air in feed line into fresh water tank?

Since you have cleaned the water filter on the low pressure side of the water pump, you should also ensure there is no air leaking into that side of the water pump also. It is not unusual to have a bad seal on the filter cap or a hidden crack in the filter cap or body after the cleaning procedure. Overtightening the cap can result in having to buy a new filter off Amazon or eBay. They are cheap if that is your problem.

I agree: if we can safely assume that you did get the filter clean...
1. Start looking for air leaks
2. While checking for leaks: look for kinks in the hose someplace downstream from your pump
3. If it's not that obvious or simple: take another look at the
pump, and how it is functioning.

Good luck!

Is the valve between the tank and the pump fully open?

Thanks for the replies. I dont see any way to adjust pressure on the pump. Dont see any kinks in the hoses or visible cracks. Is there a particular way to check for air leaks? Ill look closer tomorrow.

Water

My bus had a lift up valve for draining water near the pump. Sometimes the ring on top (looks like a key ring) would catch and the valve did not fully seat. This let the pump suck in air and caused little to no water flow.

I had posted this water pump trouble shooting hyperlink in another post recently. It is a good starting reference. Although it simplifies the solutions without much explanation, it is helpful to see some typical problems and the things to try to fix them.

You mentioned you checked the filter. Did you also check the small filter screen on the inlet side of the pump. If not simply unscrew, remove the screen, clean out and reinstall.

We have had the same issues with our 2017 Axis 24.1. Check my post "water pressure issues - solved. Plastic shavings clogged our water line at the tank side of the white flexible hose. Maybe that is causing your problems too.

Just getting a chance to update this post. When I initially cleaned the filter, removing small bits of plastic shavings, and checked the lines it didnt appear to make a difference in performance, but after trying the water pump a few more times during the trip it did improve and was working pretty well. Now that were home Ill use my compressor to blow out the lines.

I had the same problem when we bought our Thor back in March, it turned out to be the inlet screen/filter that screwed onto the pump had a crack in and was sucking air,so I just removed the screen and hooke line from tank directly to tank and it works great now.

I also forgot about replacing the screen until I saw this post.
