Plumbing Lines

[JohnF]

I took a picture of my plumbing near the pump and am trying to figure out what and where the water lines go. Since they don’t provide a diagram and I can’t see where the lines go throughout the camper, I am guessing here. Do you agree or disagree with what I have so far?

John,
I believe your city water in is the hose going to your hose coming in from fw tank that you have a question mark by.

A pump has a suction and a discharge. usually you cannot run the flow backwards through a pump. So I think the dark blue line goes to the waterheater and the other to cold on faucets. One side of the pump is intake the other side is discharge.

I agree with turbo. City water arrow should point to the line with the question mark and connects up with the line marked from tank. I believe the black thing where the two meet is a two way valve that pulls water from the tank if there isn't any pressure from city water. The outlet of the filter, is the blue line that feeds the cold water to sinks, etc. and the other white line feeds the water heater..

[JohnF]

So here is the updated image. The blue line is where the water filter was. You can see the two mounting holes in the aluminum above it. If this drawing is correct then FR only filtered the cold water?

Hey I am not buying the ? is City water in.That is the Suction side of the Pump. I would more believe it to be A/F inlet.The other hose is F/W tank coming to the Suction side of the Pump. Youroo!!

Ok. Now I'm confused. As I look at it further I'm not sure what you have. Did you take out the water filter? On my trailer I have a single line from the tank to the inlet of the pump. On the outlet side I have the outlet of the pump feeding a two way valve and also the hose from city water which is filtered. If there is pressure from city water the valve pulls from there. No city water, I turn on the pump and it pulls from the tank and closes off the feed from the city inlet. The valve feeds the cold water faucets and the hot water heater.

My city water tees into the fw tank line I believe.
I'll look .

Here is a picture before the filter was removed. The filter simply was installed in the blue line I have now.

I believe that you have everything listed correct in the second pic. the filter only filtered the water going to the sinks. The hot water heater supply did not run through the filter. Just used the metal screen in front of pump to catch the big hunks.

[RJHuser]

I disagree!

I think your picture in the first post is correct, with the line with the question mark being the antifreeze suction line.

Why? To the inlet side of the pump (if you look close you can see the suction strainer) one line is from the tank the other line would not be the city fill. The city line does not go through the pump. Thus, the other side of the pump is the discharge. The pump discharge line goes to one side of the tee and the city fill goes to the other side of the tee. The tee branch connection then goes to all the cold water faucets AND the water heater. The integral check valve in the pump prevents the city fill from flowing backward through the pump to the tank.

Rick,

If you are correct, then what would prevent the pump water from exiting through the city water line? Is their a check valve in the city water hose inlet?

John

[RJHuser]

No, as I said, the check valve is integral to the pump. If you look, there have been many posts in the past with people having their tank slowly filling up due to the check valve in the pump failing.

Rick

Edit:

Whoops, I didn't read your question right.

Yes, there is a check valve in the city fill fitting. Again, there have been many posts in the past where, when on the pump, water is shooting out of the city fill. If you pull the screen washer out of the city fill you can see this check valve. Many times when water is coming out of the city fill, pushing on the stem of this check valve will fix the problem.

Did it come equipped with a antifreeze suction line? Mine did not, reading the internet real quick on your TT. I didnt find anything to suggest that it did. Maybe overlooked it, but didnt find anything.

[PhoneDude 8289]

Looks to me like RJHuser in post 11 and 13 is correct if you have the installed antifreeze line.

Is the black device near the pump a selector valve, and where does the blue line terminate? If black item is selector valve then, that is the inlet side of pump, one line from potable tank other line goes into anti-freeze jug. Check valve normally installed on pump outlet. Good luck.

[JohnF]

I believe this is the installed antifreeze line you are referring to.

[JohnF]

Okay, I believe this is correct. It would allow ALL water to be filtered through the original filter and explains the two way valve used to winterize the unit.

I thought it all along, just didn’t want to upset the others.
