My suggestion is to do away with the frost free hose spigot. I used to have them in CT and they had a very short life span. Years ago I switched to a standard hose bib and installed ball valves in the basement. In winter I simply shut off the valves and open the hose bibs. I have never had a problem since I switched.
If you look at the 1st pic right at 11" you will see the copper grooved. The springs goes in and gorove stops spring. 2nd piece with washer just slides in.
The brand would be a letter or two or three in the casting on the side of the valve.
Even with the brand it's hard to get the right parts.
I have a box of different length inserts for frost free valves because every valve and even between the same manufacturer is different. My advice.... replace the valve. Keep the card/ID for the new one in a safe place for future rebuild.
My hot water heater started knocking so I took step to clean it.
Turned out the knocking was coming from inside a wall.
I have a wall that separates my 2 from my 3 car garage.
The previous owner took a water softer with them when they sold the place, the piping is still there for it.
That piping runs back inside the wall down low. Turns out the knocking is inside that wall when pressure is relieved/water is in use inside the house.
What would be in the wall to cause this?
During Traveling
I was planning to turn off the water but realized that if I do that, rodents might chew on unpressured PEX Pipes. I don't know if the pressure makes any difference but have had the PEX Pipes installed 3 years ago. To date, there has been no problem with PEX Pipes. I do hear roof rats in the attic once in a while but this year has been good since I found RatX and seems like it is killing them before they are getting into the house. I already tried to seal all entry points in the attic but once in a while, still hear one. Yes, I understand that I should hire a professional and plug up all entry points in the attic.
I also need to leave the water on for the sprinkler and timer.
Two good things are none of the PEX Pipes run into the attic since I live in a two story home. Also, rats do not go into my attic during the summer time since it is super hot.
For now, is there a water pressure unit of some type that I can connect to a faucet and will send me an APP notification to my phone when the pressure of the water changes? Similar to this or the meter infront of our houses:
