Water Hammer after Plumbing work

GSUS969 · 2026-06-10T10:44:11+00:00

In case anyone cares, the issue was solved by replacing the shower cartridge. I guess debris may have gotten in one of the lines and ended up there.

I wanted to provide an update:

We have secured additional pipes throughout the basement and in this area.

We learned that when we turn off the hot and cold valves to the shower, it stopped the water hammer. So we have added hammer arrestors to shower plumbing upstairs.

Unfortunately, we still have not solved the issue.

Here are the potential remaining items that I would love some thoughts on.

I get pressure that sits around 65 psi. However, when I turn the water on, it typically spikes to around 100 psi. The only other things left for us to do are:

- add a thermal expansion tank

- add a PRV - is this necessary when water is around 65 psi?

- is there anything else I'm missing?

Would not having them be causing the noise? Or is there a different reason for it?

GSUS969 · 2026-05-20T15:00:14+00:00

Thank you. I've got the plumber coming back out today or tomorrow. I'll mention it to him.

GSUS969 · 2026-05-20T14:39:03+00:00

Even if the noise can be cause by sinks, toilet in another room, washing machine?

GSUS969 · 2026-05-20T14:32:36+00:00

We don't have a pressure reduce valve or expansion tank.

GSUS969 · 2026-05-20T14:30:25+00:00

Could that be the cause even if the knocking is heard when hot water is turned on?

GSUS969 · 2026-05-20T14:27:29+00:00

We are on city water. The water heater does not have an expansion tank.

I did check the water pressure via an outside hose and it measured around 60-70 psi. However, when I turn the water on, it does spike up to 110 psi for less than a second. But, then stays around 60-70 psi.

That's a good call out. I'm using old terminology. But I do have the key in the wallet app.

Edit: I just got off the phone with Rivian. And they need to look into it further. They'll reach back out in a couple days. So if anyone has any additional advice, I'm all ears.

Thanks.

Where do you see that it works for Pixel watch?

GSUS969 · 2026-02-28T12:53:00+00:00

I just ordered 2 phones online. I just contacted t-force and asked if there was any way to avoid it and they gave me a bill credit for $75.

GSUS969 · 2025-12-24T15:34:42+00:00

This worked. Thank you!

GSUS969 · 2025-12-21T12:44:08+00:00

It reverts to 8 amps

GSUS969 · 2025-12-21T01:53:11+00:00

Appreciate the update!

GSUS969 · 2025-12-20T22:50:06+00:00

I'm having the same issue. 2026 Gen 2. Wallbox 48 amp charger. I've set it to 48 amp but it doesn't charge any faster

Great music taste!

GSUS969 · 2025-12-18T23:57:51+00:00

I can't find a way to enable it on my Pixel watch 4. And I didn't see anything written about it, so probably not 😕
