We dry camped in late June with no issues. Then we dry camped in early October. Found that we had very little water flow and low pressure. The water tank was full and the pump did run. We made it through the weekend with our bottled water. After arriving home we extended the slide to unpack and started to troubleshoot our water issue. But to our surprise we have normal water flow and pressure. So the question I have is; it possible that our full slide kinked or pinched the water line? Should I rebuild or replace the pump?

Thank you for any input.

Thank you for any input.

Is this while using the pump with no city water hooked up? Kinked line is possible if you have water in the slide. Yes water pumps are rebuildable and done cheaply. No need for new. However I would be sure you have a pump problem before going thru all that.

Water pump bypass valved used for winterizing closed tight?

Where were you in early OCT. and what was the temp? Water possibly frozen? Got down to 30 in MA in OCT this year. (Back in FL now) water was frozen in the AM one day. Water hose laying on the ground. Thawed out quickly.

That happened to us and it was the sediment filter going into the pump. I whacked it a few times with the rubber handle of a screwdriver and it started working. I am ordering a new filter from Amazon.

Were ALL the faucets in the coach effected? It's possible the slide affected any water lines in the slide (is that where your galley is?), bit not possible it caused a problem elsewhere.

The more likely problems were:
1. Some debris in the fresh tank blocked the pump intake line, either at the tank end or at the pump itself. The drive home may have dislodged it. There should be a strainer at the pump inlet - check that.

2. The City water Fill (aka pump bypass) may have been open, perhaps only slightly. That will cause major pressure and flow loss in the main water lines.

Thank you for your replies. Here some answers to your questions.
1. No city hook up in TN, using water pump only.
2. We were in Tennessee and live in North Carolina. No freezing weather.
3. I did check the small filter on pump intake. It was clear.
4. I am 99% sure that I had the valve set to tank fill as I filled the tank just prior to travel.
5. I could not check the tank for debris blocking the pump line. I can't see through the tank.
6. Water bypass valves were in the correct position.
7. All faucets were affected and the toilet.
8. Our kitchen sink is in the slide unit but not the bathroom.
9. Hot water tank is in the slide.

I am leaning towards debris blocking the tank outlet line since the bathroom was also affected. Cold water lines should go to bathroom first (probably on a tee from main line).

Thanks

Item #4
Tank FILL position is for filling the fresh water tank'
With it still OPEN and trying to use pump...low flow/pressure due to pump discharge going back into fresh waater tank
Round-Robin...pump sucks from fresh water tank and then discharges back to fresh water tank
