Posting again with updates and a call for advice on continuing “ticking†noise I’m getting from my pipes. I’ve been able to shoot some video to capture the issue in hopes that I can give this group a better sense of what is happening.
As background, I am on standard city water. My set-up along the main line includes a whole-house water filter, water meter and PRV valve (see picture) with a hot water tank about 5-6 feet away. The PRV valve was replaced about 9 years ago and the whole house water filter was installed approximately 6 or so years ago. The hot water tank was also replaced about 6 or so years ago.
Here is a photo of the setup:
During this time we had no issues. Then about 10 months ago we started noticing that the pipes had started making various noises that including ticking, thumping, and squeaking. I think it may have started even earlier but was something that didn’t really catch our attention. Now the noise fluctuates from barely noticeable to waking us up in the middle of the night.
Here is a video that attempts to capture the noise. It captures some of the squeaking but the “thumping†didn’t come through in the audio (but its there). Note when I close the water supply toward the end that the squeaking noise really jumps.

There is no rhyme or reason that we can figure out for why it happens, though it tends to happen more in the morning and evening. Working from home today the noise stopped being noticeable at around 10am, except for a brief period at about 2pm.
Here is what we have done:
-Eight months ago we replaced the water meter at the suggestion of our plumber. That didn’t work.
-We then replaced the PRV valve. The noise picked up again after about 48 hours.
-We tested toilet leakages to see if anything was pulling water. They were all fine.
-We replaced the line and filter into the upstairs freezer. No change.
I called another plumber out who immediately felt that the PRV was faulty. He put a water pressure test gauge on the outside nozzle. The pressure was in spec, about 60 PSI, but then it started to rise about 6-8 psi and then fall again. This happened a couple of times. He suggested I monitor the pressure myself and then call the original company out to replace the PRV under warranty.
I installed my own test gauge with a tattle-tale needle. Things were fine at about 58 PSI, but then I came out later and saw that it had jumped to about 66 or 68 PSI depending on how you interpret the reading. I then heard the noise and went to look at the gauge and found it jumping up and down.
I’ve attached a video of this happening.

So I’m prepared to call out my original plumber to talk about replacing the PRV based on the above, but thought I would check in here for advice first.
Couple of other things:
-I do not have a water expansion tank, and am completely confused about the need for one. I’ve read online that I absolutely need one, but both of my plumbers have told me that I do not and they are both highly rated on Angie’s list. There is no leaking from my hot water tank at all.
-I did see a suggestion that if I turn off the hot water heater I could monitor the test gauge and see if that changes. If it doesn’t that probably confirms need for expansion tank. Does that make sense?
-I’ve also seen another thread where the issue is the whole house water filter having a check valve:
https://terrylove.com/forums/showth...-water-filter-turned-on-(not-run-of-the-mill)
I could try to switch out my water filter as well with one that does not have a check valve.
Having said that, I’ve had my current setup for a number of years without issue, so I’m reluctant to add an expansion tank or replace the filter…though I guess at some point, I have to try something!!
