We have a 2018 Dutch Star. The other day I used auto fill to fill the fresh water tank. When it was filling the fresh water tank, it seemed to turn off all the other water spigots in the motor home. Is that normal and is that how it works in your motor home?

Did you have your water pump turned on? When using autofill, I think you can only use water from the freshwater tank and not the city supply. That requires the pump.

I say "I think" because I never use the autofill function. It is easy enough to monitor the tank and fill it manually when needed.

No, I didn't have the water pump on at the time. I will try that next time I auto fill.

Thanks.

The problem is, when the tanks are filling, all the pressure/flow is diverted, thus losing pressure to the fixtures.

You must turn the pump ON, to augment the city pressure.

This raises a question I didn't know I even thought before to ask. I always run water using the water pump from the FW tank as I thought that all water had to go through the tank.

If you connect up to a water supply source, can you supply the coach without using water from the tank, by turning off the water pump and run off of regulated pressure city source?

The answer to your question is YES.

Yes, you can...PROVIDED that the CG has adequate pressure and flow.

This would be the SOP for hookups, and leave your AutoFill disabled or shut off. You would, therefore, be using city water directly and never fill your tank.

Yes, you can get water directly from a water source without going through the fresh water tank. Anytime you connect to a water source you must be sure the water pressure is less than 60 psi. The lever in the wet bay/water compartment must still be flipped to the auto fill position and not in the manual position.

As a clarification, you don't need to worry about the water pressure at the source (park spigot) AS LONG AS YOU HAVE A PRESSURE REGULATOR IN THE SYSTEM!

I don't understand why anyone with a RV would not have such a regulator...and use it. A decent, high-flow, pressure regulator can be purchased for $30, or less. Installed at the source, it will protect the coach and its water system from potential over-pressure damage that could result in thousands of dollars worth of repair costs.

Great information! We have a bad habit of keeping the water pump on 100% of the time, and even when stored. I need to break this bad habit, and this new information will help! I would much rather travel with 1/4 tank of water than the Full tank I have been traveling with, since we have hookups 90% of the time we are out.

I always have the pressure regulator (and carry a spare) and even have it before my water splitter attached to the water source.
