Installing an accumulator will probably help. If you do this, it doesn't have to be inline. You can dead end a cold water line into the accumulator at any convenient point. Keep in mind that you may want to be able to remove and replace the accumulator from time to time for winterizing.

Not a good idea to use the water at the dump station to fill your freshwater tank. It is usually marked "non-potable". Can't you move closer to the house so you can fill from a spigot at the house? Of course, you may not want to travel with a full water tank - a lot of weight.

Hi Dave,
I thought of borrowing a neighbor's hose, but then I'm not sure I want to drive around with a full holding tank either. I'll probably just add enough water by hand to overcome the RV's sideway lean and test again. If I can't get the system pressurized and functioning properly I'll chalk it up to a bad pump and head to Amazon. I've researched a replacement and I'm thinking 4088 (Revolution) from ShurFlo.
Not potable? So where do RV folk fill up on fresh water?

I came across people suggesting pressurizing tanks. I'm not sure I understand the working principle of those altogether. Personal comfort tells me to get the pump working before making improvements --

Most campgrounds have some place you can get water, although you may end up carrying it . . . no different than your house.
So I manually filled just over half of the fresh water tank and ran the pump. As expected, It pressurized and then cut out. When testing out the water heater I found both bipass valves were set. I opened the valves, the pump promptly filled the hot water heater and again cut out. I thoroughly bled the air from the system.
As I have zero experience with RV water systems, I can't say for sure that the pump is bad. It is however making an awful lot of noise and seems to be 'struggling'. Also, no matter how many times the pump pressurizes and cuts out, the sputtering never seems to go away entirely.
I ordered a new ShurFlo 4008-101-E65 3.0 Revolution from Amazon and also bought the inline strainer to keep large debris fragments out of my new pump as is called for in the manual. I received the new pump later in the week and installation has been anything but smooth. My Winnie has the old gray polybutylene tubing which I suspect is 3/8" diameter. While both old and new pumps are essentially the same shape, the old pump had a metal base with rubber feet making for a more rigid posture -- if that can be said. The new ShurFlo 4008 has both base and feet in rubber. I imagine this makes for better vibration absorption but the pump 'leans' when used with stiff tubing.
I found some reinforced flexible hose (as recommended by ShurFlo) but I have no idea how to make it work in my situation. The fresh water tank has a short length of PB tubing leading to a drain plug. Both sides of the drain plug are threaded, seemingly 3/8" (as 1/2" NPT is too big). I am not sure what fittings to use for this type of threading. I own a standard copper ring crimping tool but the flex hose seems to big for it. I'm losing sleep over this.
