Master bedroom bathroom toilet. There is a sound of water running that seems to be coming from the pipe going into the toilet. The toilet itself is not running. In fact, this pipe also contains the valve that shuts off water to the toilet, and when I shut it off, the sound remains.
It’s annoying, and I also worry that water is running somehow/somewhere in a way that could be costing me money.
It makes no sense. The water in that pipe can’t be going anywhere (I think), and so I can’t understand why it would suddenly be making noise.
Since the day before yesterday, it has been making the same noise at the same volume no matter what.
If it’s really windy you’ll get a bit of a vacuum created in your vent which can draw water out of the bowl. That could cause the sound, but I see it’s been ongoing for a few days. Also, you’ll usually notice the water swishing around when that happens.
You might check to see if any of the other toilets in your house are running/leaking or anything else in your house that’s tricking into the drain (say a furnace drain or sump pump) and the sound is echoing up through the vent system.
There’s also the possibility that you have a clog in your drain pipe somewhere and what you’re hearing is the water that’s built up behind it slowly trickling past it.
It’s a really rushing sound, as though a lot of water were going right through that pipe, yet that’s impossible. That water has to be going into the toilet, yet it’s not going anywhere. It’s quite a mystery to me.
I could see other sound being carried by the metal of the pipe, but I don’t hear it anywhere else in the house.
When you say that you shut it off, you mean you shut it off at the shutoff under the toilet, right? (Just need to be sure).
Is the pipe under the toilet cold? As if water’s been coming into it for the last 24 hours?
Is the water in the bowl moving, like water is flowing into it?
Have you checked every other source of water and drain in the house to make sure nothing is going on there? There’s a drain behind the toilet that goes down to your basement, but it also goes up to the roof and nose can echo up through it.
You don’t want to start replacing the internal tank parts in one toilet only to find out that someone left the sink in the basement on and that’s what you’re hearing.
Cool, not frigid, and it’s been in the high 30s here yesterday and today.
Nope, no movement. I’m sure the toilet isn’t “running.” When I shut off the water to it, drain the tank, same sound.
The house is a pretty simple ranch. There’s one other bathroom with no similar sound going on. I looked at the water heater, reverse osmosis system in the kitchen, etc. No water shenanigans, it would appear.
Is there any possibility that it might sound like an animal in the vent system as opposed to water? Think claws trying to climb PVC or a birds nesting up at the top.
I have the same sound in my bathroom when the house in front of me runs water. We are on the same water main which is 1" pipe. I have a 3/4 pipe comming off of it which feeds the back house. We are maybe 40 ft apart but I still get the sound like water is running in my bathroom.
I suppose the next thing I would try is shutting off the water to the house. Then, no water can come in. Then see if you still hear the noise. If you do, then we know it’s not water being ‘pushed’ in from the mains. It’s water that’s either sitting a toilet tank, a sump pump or french drain system or maybe even a neighbor emptying their pool into the sewer and you’re hearing that echo back up through the drain system (unlikely, but I’m grasping at straws here).
Either way, I’d shut off the water to the house and check again. At least to give us something to work with.
For the record, without hearing it with my own ears, I’m still leaning towards the toilet being the culprit.
Have you taken the lid of the toilet and physically looked in there yet? You might be able to see the water running right down the overflow tube.
Are you certain that the shut off is in good working order and closes fully?
OTOH, if you shut it off and then flushed the toilet, I’d guess the bowl would have to refill before you’d hear the sound again if it had anything to do with water coming from the tank, into the bowl and then going to the drain, and you’d have seen that.
