Water Pressure: Shore pressure high, All pressure in trailer low....

[bhooves]

2013 Flying Cloud FB 27', The shore water pressure is satisfactory, but our pressure in shower, both faucets, and toilet very low. Any suggestions for clearing water line inlet, or whatever else may be the problem? We're full timers and this issue is very annoying.

I'm assuming you have tried the pump with internal tank, and everything seems OK? Are you using an external water filter?

If you have tries the pump and have OK pressure then I would look at the pressure regulator at the city connection on the trailer. That regulator should be factory set to about 45 lbs. But like everything else made in China it may not.

Try the pump if you have not and post the reaction.

Thank you for the reply. I replaced the water filter, and checked the water pressure from the hose. Very good pressure, and easily filled the fresh water tank quickly. I also used the pump to supplement the water pressure and it worked much better. Where is the pressure regulater that was factory installed located? Also, I had a technician from he factory show me how to clean the water heater. It was a demonstration, not a complete cleaning of the water heater. I think. Could dislodged lime, etc. from the water heater gotten into the cold water line as well as just the hot water line. I presume that the pressure regulator could have from China could be the culprit, so how do I go about changing it? Thank you very much for the reply. I didn't know about the factory installed regulator so you have certainly helped me take a giant step toward solving this mystery.

There is probably a small filter screen on the water inlet that is clogged. It pulls out and is easily cleaned with a wire brush. If you use an inline filter you might check that.

clean screen filters...in emergency.. replace when able..

I had a similar problem. After checking everything I could think of, I asked a fellow AS owner who said to check the screens in each faucet aerator. All were plugged up. Cleaned them and everything was fine.

My FC manual says that the city regulator is set at 65 psi;
and the water pump set at 55.

And just HOW does one clean the screen in the faucet aerators?
After reading your 'thread', I went out to check mine, (30' FC.) and I could see no way to remove the screens. They are green plastic 'thingies' in the 'bell mouth' of the faucet, and unable to grab, even with a soft jaw pliers.

Back to the problem. I using the pump gives you god flow the problem is not the screens at the faucets. Have you removed the hose at the city connection and looked at the screen just inside the hose connection. If clogged that will reduce flow.

Another test is while hooked to city water turn on any faucet. Is there a noticeable surge of water flow that quickly drops off. That would indicate the pressure regulator is supplying pressure to the system but the flow is restricted. If the hose when disconnected from the trailer flow well again I would look at the city connection screen.
