Plumbing Problems in the UK? Ask a Plumber Now.
Hi my name is ***** ***** I have been in the plumbing field for 20 years. I will be glad to help you today. Is this a newer home or older? How long has this been happening? Is the underneath plumbing accessible?
I would suggest as a test, if you remove the trap on the sink Then flush the toilet, does the shower still gurgle? I would also suggest placing a large bowl under the trap when removing it and leave the bowl there in case water does come out during this test.
Very much, yes. If you will do the test and let me know the result that would certainly send us in a direction towards a solution.
I am sorry that our messages are so far apart. I am in the U.S. so different times and I have been working a lot. It is 420 pm here now and I will be online for the next 5 or 6 hours.
Do you have a result from what I suggested?
With the sink traps removed?
When you look down the shower drain with a flashlight, do you see water? You should so, if you do that is good. If yo do not see water and you run the shower for a minute, do you see water then? You should see some standing water. If you cannot see very well then remove the shower grate. Once you do see water, will you have your assistant flush the toilet while you watch that water and see if it moves or goes down when the toilet is flushed? Sorry for all the tests, but this one very well may be the last one to determine the issue.
Alright, so there is a venting issue. The drain piping must be connected in a certain order to allow venting. When something is used it needs to pull air from a vent. The vent is a pipe that goes out of the roof and when the toilet is flushed it pulls air from the vent pipe. The toilet does not have a vent pipe and instead it is pulling air from the shower pipe and pulling the water out of the trap. This may be a very easy repair or very invasive. There is one test I would like you to do to determine if this is an easy fix or not. Will you do the same thing as the last test but first remove the traps on the sinks in the bath first? Then with the traps removed on the sinks in the bath, does the water in the shower trap still move with the traps removed?
did you do the test ? hand wounded today so messages may be short adjectives
