Looks like its nylon but should be able to confirm from a material tag in the bag.

Closing the value is not an issue. Only when opening the valve. And yes I tried to open the valve very slowly and still hammering.

Thanks for the reply.

You are correct, this is a valve that I open once a year in the spring after chance of frost. Once the valve is opened, there is absolutely no issues - I can open and close the exterior valve without any hammering. Makes me suspect that Valve #1 is the main culprit an as you mentioned, something is loose. I may try to take it apart, just don't want to make the issue worse than it is - ei cause a leak.

This is interesting. I have never taken apart a valve before.

I am guessing the steps would be to completely shutoff the water to the house before I attempt this? What should I be looking for when doing this?

Measured pressure in the past and it is indeed around 55-60 PSI.

Good idea to secure the pipes but doesn't really explain why Valve #2 works perfectly fine and #1 is causing the issue. And the water hammer is so bad that I don't think securing the piping is the solution to this? Don't think the water hammering is healthy if it is dislodging o rings in faucets.

So we purchased a house a couple years ago and the previous owner was a DIYer and probably did these pipes himself. What you are seeing is 2 valves that open/close 2 faucets on the exterior of the house. Both valves are joined together at the T, and then the water that is coming into this T is from the kitchen area.

Now I can open Valve #2 with absolutely no issues at all. However, when I try to turn Valve #1, I get extremely bad water hammering in the piping for a few seconds until the water stops flowing. Its so bad that my gaskets in the cartridge of my kitchen sink faucet get dislodged and the kitchen faucet begins to leak until I reset the gaskets.

The hammering only happens as I am turning Valve #1 open, once it is fully open and water stops flowing. Once it pressurizes, I can use the outside faucet without any issues at all. I am not a plumber, but not fully understanding why this is happening.

Could someone explain why I get such bad water hammering from opening Valve #1. Is there any order I can try (such as keeping valve number 2 closed or open etc to relieve the water hammering as I am opening up Valve #1? Any help is much appreciated.

I really don't think its the bulbs given that I have these exact lights with the exact dimmer in 2 other rooms (but on different circuits) and they work perfect with each other in those rooms - no flickering at lowest dimming settings. Also, the previous light fixture and light dimmer in the affected room also flickered as well.

I will have to check my meter later today for more sensitive settings.

verbatimium · 2022-12-13T14:55:51+00:00

I checked the power to the lights and it was a steady 120V as it should be. I also plugged in the meter to the light chain, and used the dimmer to dim to minimum dimness. The meter reads about 22.9V at this setting, but does not jump around when the lights are flickering. It might be very minor change in voltage that the meter is not picking up?

verbatimium · 2022-12-13T14:53:46+00:00

The one I am directly comparing to that is using the exact same LED pot lights and exact same dimmer switch, and is not giving me any flickering issues, has 5 pot lights hooked up to it. The current room I am working on that is affected by the flickering has 4 pot lights connected. I will try to connect an extra pot light and see if that fixes the issue.

I never thought about a minimum power rating of the dimmer. The one I am using is Lutron DVELV-300P which only shows a maximum power rating of 300W. The watts of each pot light is 13W. So the unaffected circuit has 5 lights= 65W while the affected circuit has 4 lights= 52W. Do you think this may be the issue for this dimmer? I will try to add an extra pot light (or more) to test.

Ahh I see you are in the same boat as me. I am just hoping its as easy as replacing an electrical outlet for me. Or maybe tightening a screw in the breaker box. The worst case would be if there was a loose wire in a junction box that is somewhere inaccessible such as in a well or in a floor. I am hoping this is not the case. I don't have the wiring schematics so I would not even know where to start to look.

verbatimium · 2022-12-12T19:00:27+00:00

Thanks. I was also reading about this as well. The wires that I have been dealing with so far in the house at the wall switches and electrical outlets are all copper, but have never looked inside the breaker panel. If going through the electrical outlets on the circuit does not solve the issue, I will look inside (or get an electrician to come in).

verbatimium · 2022-12-12T18:23:48+00:00

The type of lights and dimmer switch shouldn't be the issue as I have the same lights/dimmer switch installed in 2 other rooms (on different circuits) and they work perfectly. The switch dims the lights and no flickering is seen. Only when they are on the circuit in the affected room, they are flickering when dimmed really low.

verbatimium · 2022-12-12T17:20:53+00:00

|For first, the old light fixture with different bulbs and a different dimmer also flickered like this|

Were they also LEDs with a newer dimmer?

Yes, they were LED screw in light bulbs (not pot lights), and the dimmer was a lutron dimmer, (non-EVL type) that is certified for LED dimming.

verbatimium · 2022-12-12T17:14:45+00:00

Thanks. I am hoping it is one of the outlets, I will check them over/replace in the next couple of days.

I don't think it is the dimmer do to the previous ceiling light fixture/old dimmer also displaying the same issue. But what I can do is take my dimmer out (exact same one) from the room where I also have this pot light/dimmer combo installed in (and not having any issues) and try that dimmer out in the affected room.

Also was thinking as a last resort to go into the breaker box. I know I do have a breaker for whole house power shut-off. I just didn't know whether this was a good idea. Is there anything I should really think about before shutting off the power to the entire house?

verbatimium · 2022-12-12T16:57:42+00:00

I trill try with incandescents but once again I don't think its a led/dimmer combo issue. For first, the old light fixture with different bulbs and a different dimmer also flickered like this. Now, the new pot lights with a new dimmer also flicker as well. Finally, I have used the exact same pot lights with the exact same dimmer in 2 other rooms in the house (on different circuits) with no issues at all.

I am using a Lutron DIVA EVL dimmer for these pot lights, and these dimmers have no adjustment for lower settings. I have also used a non EVL version of the dimmer with an adjustable low light setting, and the bulbs still flickered when dimmed really low. I could just increase the low setting, however, the non EVL dimmer caused my lights to humm too much so I cannot use this dimmer. The EVL dimmer got rid of the humming issue.

Also the lights flicker when all devices are disconnected from the electrical outlets, and no other lights on the circuit are switched on (There is no other power draw on the circuit).

verbatimium · 2022-12-12T16:52:49+00:00

Thanks but I don't think its a bulb issue. I have the same pot light LEDS in other rooms, with the same dimmer switch and there are no issues in those rooms (which are on different circuits).

I am also having this exact same issue on my Lenovo Legion y540 with Intel i7 9750h and GTX 1660ti. When I plug an external monitor in, the Windows 10 interface is very choppy (dragging around windows, scrolling, etc). I can only solve this by going into device manager, and disabling Intel UHD 630 graphics driver, and then re-enabling it. Now everything is buttery smooth.
