Hot water coming into toilet?

[ukmark]

I'm a newbie so take it easy on me. We have a 2015.5 Cherokee 255P Fifth Wheel. From day one the hot water and cold water were reversed, (easy fix on the sinks and shower, just changed out the handles) but hot water also flows into the toilet instead of cold water. I've tried every imaginable combination of valve positions under the sink but I can't for the life of me get it correct??? It's beginning to become a problem since I now spend much more time in the RV. Any Ideas??? Thanks, Mark

Your water could be mixing if your outside shower knobs are turned on and the button on the head is in the off position. I would check that.

The fact that the hot and cold were reversed tends to lean toward the toilet being teed off the hot water line instead of the cold. Confusion could have run rampant during construction. Same guy did all the plumbing interconnects and self inspections.

Thanks Bruce but I checked that first thing...

The lines might be reversed by the HWH, that is why all the taps and sinks are reversed. Water coming out of the heater are going into the cold water line and vice versa. If the factory mixed up the blue and the red. Just a thought.

Assuming these are the valves you are talking about, this should help.




Your valves should be positioned as shown in the top picture for normal usage.

You got to many posts going on the same thing.. Gonna confuse us slower folk..

The site team has merged two duplicate threads about the same subject. Please only post a question one time and in one thread. if you need it moved to perhaps a different subforum, then all you have to do is ask a site team member to do this for you.

Hope you get your problem solved, but it does sound like it is plumbed wrong from the water heater forward.

That looks right.. Check the outside shower idea from above. That seems to get a bunch of folks.. But my guess it might just be the way it is somewhere near the camode if you are getting that much heat to notice it.

the blue lines (cold) are supposed to be at bottom of water heater (the inlet).

Red lines (hot) are supposed to at top of water heater (outlet)

The black valve. It goes from a red line to a blue one. Check to see if that valve is closed. If it's open,when you turn on cold water, the hot water, from the HWH, will go into the blue line and then to your sinks or toilet.
The top one needs to be open, that feeds your HWH. The valves allow you to bypass the HWH, when winterizing. You might have forgotten or missed closing that valve.
The valve at the bottom should be open. I'm guessing it is, cause your getting hot water everywhere

The picture almost cuts it off but I think the blue line does go into the bottom and the red goes into the top. They plumbed it oddly though.

I don't think that's the case. Again, the picture cuts it off. Maybe the OP could post another one that's a few inches lower?

The valve on the vertical water line, in the middle of the picture. The line goes from red to blue at the valve. That valve needs to be closed. The two valves on the horizontal lines, blue and red need to be open. It's the bypass system.

I'll post a better picture later tonight. Thanks for all the help, I really appreciate it!!

According to the pic, everything is as suppose to be for a working system, not in bypass. One other possibility could be that the cold lines run along with the hot long enough that the heat from the hot is transferred to the cold line.

I'm curious to know how you know the toilet water is hot

[bubbles]

The picture shows the water heater connections are correct (by tube color) and the valves are correct (for usage) regardless the colors. I think the tap for the toilet is at the wrong tubing (hot vs cold). One way to tell might be to close the red tube valve in the photo at the water heater and see if the toilet still has water flow after all pressure has been released. If the toilet has good water flow it is plumbed correctly.

[ukmark]

This is a current photo, it appears all the valve positions are correct however I just noticed that by touching the blue line coming from the HWH, it is hot and the red is cold. ??????

Is the vinyl hose that connects to the tee that tees into the tee to the left with the red tube going up and down your city water in supply?
Can you post a photo showing the line from the water pump teeing into the system. What i can see does not look right. It kinda looks like the pump would connect to the right side of the big white tee, if so it is hooked up backwards and they should have capped that tee and teed into the blue line next to it. Then you will need to reverse the sinks again.
