Dripping/ticking sound when shower used
An upstairs bathroom shower I usualy only use, so probably why I have never noticed the noise. But my son has been home from school the last 6 weeks, and notice a ticking/dripping sound when he has a shower. The sound could of been there since we moved into the house, but since I am the only one that usualy uses that shower, I would never hear it.
I can find no water stains of any sort, and it seems to comes from the end of the tub/shower that has no drain or the shower head. We also recently got a tankless system installed as well, although the only lines relocated where the runs in the furnance room due to location. So not sure of that has anything to do with it. I doubt it since hot water is hot water
Can sound travel from the drain end of a tub to the other side. Its not a constant sound either, its random, sometimes its fast, sometimes is slow, or in between. Once the shower is over, it stops. I haven't timed how long it takes to stop yet.
Ive looked for any kind of water damage, to the closet below in the entrance where I hear the sound, all the way to the basement I followed the drain line. Nothing I can see
Heat expansion of a pipe rubbing? Just the drip from the drain travelling?
Any ideas would be appreciated.
