Help with low water pressure

2013 340 RK Columbus. Tell me if this will work. If I have low pressure from the campground, can I connect campground supply to the winterize connection, swap the blue valve from normal to winterize, and use the pump as a booster pump. If it won't work, why not. Thanks in advance.
Paul

Why not just fill the fresh water tank and use the internal pump?

Were doing that now. It took at least 30 - 45 min to fill the tank. Looking for another altrnative.

I am not the expert here but if the pump flow exceeds the water volume coming out of the hose, you could damage the pump as you would keep running it dry and not gain any additional water pressure

When I have low pressure, I fill the fresh water tank, and reconnect the water supply to the RV site supply inlet, when I need additional pressure turn the pump on and it augments the campground supply. Basically use both and I do not use a full tank on a trip.

Also, have an Oxygenics shower head which helps.

Bill m That sounds like a reasonable option. will try in the AM. Thanks. I too am concerned about the pump not getting enough water.

Attach the shore water hose to the winterize connection and open the valve. With your FW tank to pump suction valve open (it normally is), you will backfill your FW tank in about 5 minutes. Be careful and make sure your vents are open. (Open the cap to the normal FW tank fill connection.) Otherwise you'll blow up your tank - not good. This is how I rinse out my tank after I've sanitized it.

To do what you want to do, you would do the same, except you'd close the pump suction valve to the FW tank so you don't fill the FW tank. I'm not sure exactly what might happen if you try this. Seems like as soon as the campground + pump pressure rose to the pump cutoff pressure, the pump would stop. So you wouldn't be any better off than pumping from the FW tank, except that you wouldn't have to refill the tank. On the other hand, putting 20-30 psig water to the suction of the pump, which isn't per design, might do bad things to the pump.

You could use the fresh water tank as stated. Just don't let the tank run dry and it will not take as long to fill. You will have to refill the tank more often but not a long each time.

Try removing the waterpur filter, I had very low pressure from external water supply on my Columbus 320, it is only a couple of months since I took delivery. I removed the filter and that solved my low pressure problem!


Happy Camping!!!
