I recently had a new P Trap for my shower. It is roughly 30 inches from the toilet . I noticed the water in the P Trap sometimes turns a bit yellow when the toilet is flushed
Is this a cause for concern? Is it possible the toilet is backing up into the shower?
Everything drains well, there is no smell, there is no water movement in the trap when the toilet is flushed
Who put the trap in?
Can I invoke the 5th amendment? I did have a plumber look at the rough in. It is pitched correctly, maybe not enough?. It's in a slab. The old P Trap was cut out. At that time when the toilet was flushed there was nothing coming out of the cut-off pipe running horizontal.
In my own defense, I called 3 plumbers and none wanted the job. As I said, one did actually look at it. I offered cash money.
Why a "new" trap for shower? Are you looking down into the shower drain? Put some blue food coloring into the toilet, flush. Do you see blue in the drain?? Not good!
HOW you connected the "P" trap to the toilet line would make a diagnosis easier, as to whether the toilet water COULD get to the shower. What kind of plumbers did you call? I do not know any which would refuse a simple job like that, unless you were trying to get a "moonlighter" to do it inexpensively. I charge the same whether it is cash or check.
Yellow water in the trap? How do you even see that?
--I just point the flashlight down the drain; no smell

--The new trap was for a tub to shower conversion. The old trap was 2inch, but the drain pipe going in was permanently sealed 1.5 inch. I did try Tomato Juice in the toilet; no color change; I suppose thatís a good sign
What Kind of plumbers did I call?
--Every one the home inspector had recommended; plus I grabbed the guy working on the house next door and had him look at it

--The photo is not the actual, but a very similar situation. The red line is where I cut
In other words, you did NOT make a new connection to the toilet pipe, but cut off the old trap and installed a new one? If that is the case, then we cannot even guess if there is some condition under the concrete which could cause your "problem".
