Tried that. There's good flow to the holding tank from city

Before you throw $s at this consider:
1. Make sure the water tank is at least 1/4 full.
2. Make all the settings so the pump should deliver water to the coach.
3. Turn the pump on and see if you have water.

I suggest this because you have moved many of the levers for directing water. This will reset everything back to where it should be.

Do the same for city water as the source to the coach.

If you still have no water, the suggestion in post #11 as to where to focus remains valid.

Check, check, and check. I Forgot to add that when pump was running, I took off the clear plastic cover with the metal screen filter in it on the pump and water gushed out. Had decent pressure there. I would think it was the pump intake side . On the other side is a screw on attachment that has a hose going upward. I assume its the outlet. Unscrewed and water was spraying out with good pressure.

Once I read there was some kind of something in the intake at where the hose hooked up to the coach, it was stuck and didn't let water flow in it, but that wouldnt be the case if you were able to fill the tank.

Just a thought.

Anewtoi, strange issue.

- if you have water in your fresh water tank, lever to city water service in wet bay, pressure off at the external hydrant...pump comes on when faucet inside coach is open and no water.
- you have no water to faucet when pressure turned on at the external hydrant and pump switch off, you have a break or clog at the common point where water enters the coach.
- there are one way valves at both the water pump and the city water inlet...see this diagram..most coaches look this way..

Thak rkh, I hadn't thought about looking for a diagram. I'm sure that'll put me where I need to be

Another question, would I be able to get a comparable valve at lowes or would it have to be rv specific. No rv place near and I work till late

anewtoi, I dont think you need any valves..I know this is frustrating, you gets lots of advise from great people here..but still nothing works...been there a few times myself, friend...
If you are sure you have plenty of water in your fresh water holding tank, or tanks as some coaches have split tanks just for ease of manufacture. They would be connected via a 2" hose that isn't likely clogged. Anyway, if you have water, and you get no water at ANY faucet, yet you've confirmed pump works because you removed line off the supply side of the pump and in ran water.
You also confirmed that with water pump turned off, and pressure connected to city water inlet, with valve turned to city service, you get no water at any faucet.
You also confirmed that you can "fill" your fresh water holding tank via the city water inlet with lever turned to city water fill. Water runs freely into tank...

If all the above is true, there would be nothing wrong with any valves, levers, one way valves. You have to have a blockage at the juncture where water enters the coach that is beyond the pump supply line and city inlet supply. You can do a search on your year, make, model coach to find your specific plumbing diagrams...

I had a problem with the pressure regulator in my Monaco. Water pressure was pitiful on city, not bad on the pump. You may have a pressure regulator or restrictor, which often includes a dial gauge (but does not have to), that has become blocked. I just took mine out and have not had a problem without it. I also eventually took out the filters as they were really no help when winterizing, I will probably put a regulator on the filter assembly and connect all of it to the water supply at the hook up.

Hmm, that's one thing I didn't think to mention. There are no filters but when you open the filter valves high pressure water is there.

I think you need to replace the 3 way valve that determines city water or tank fill. My friend has the same coach as your and had the same problem
Last month. Replace the valve.
Lowes or HD don't have them
We got one at Graingers cost was about $26.00.

No choice but to try that next. It just weird that neither tank nor city provides water inside. I Tried bypassing the built in pressure reducer, tried everything else. No luck. Now I have pump running and water in the tank and still nothing

So this is my latest blunder. Turns out that while loading up from tailgating, I shoved my BGE in the small compartment where I normally keep it. Only this time, It turned the filtration outlet valve. I member clearly. Water spewing, I rushed and shut it off. Turns out, either road bumps while driving or shoving grill in while loading BROKE the valve. Now it turns freely 360*. I must have turned it to off in the basement AND off inside also. Don't know if it should turn 360* to shut off inside or not but I never thought to turn it to see if it was the problem. Lesson learned and it only cost me about 3 showerless days. I knew there had to be another shut off valve somewhere. Was just to weird with all the variables. Thanks for all the suggestions
