Since this is about home repair, I've got a story to tell.
Almost two weeks ago we had a bad storm and that night a lightening strike hit very close to our house. One circuit breaker tripped in the breaker box. The WiFi was taken out immediately, the hot water tap had red brown rust coming out of it and the water pressure was low. I found two panes of glass broken in the basement and the ring doorbell would not work (WIFI?).
The WIFI was a no-brainer. My VOM showed that I had power on the power cord but no keep-alive led on the router at all. I took the wireless gateway router to Xfinity the next day and got a replacement.
The Ring doorbell was blown-up and I measured the 18 volts getting to the device to prove it. Goodbye Ring doorbell, we never like it anyway.
I decided to just wait to see if the rust in the water heater would settle back to the bottom but the next morning I found that the low pressure was because the old galvanized pipe from the street was making a big puddle in our yard. The water meter at the street was running crazy. The plumber said over sixty year old galvanized pipe is hopeless to repair so they but in PEX for our main entrance and upgraded to meet the current code. As our plumber was just arriving to lay the new pipe, the city water crew showed up in our intersection to repair a ruptured main that had to have been hit by the same lightening strike.
A day or two later I saw some water coming from the water heater, and the next day I saw more water. I've had a water heater fail in the past and flood the basement, so I called the plumber and had it replaced and of course brought it up to code.
Then I happen to think that I have lost my cold water pipe ground since it's plastic main pipe now and a sixty plus year old home here in the South had no grounding rod, so I called the electrician. They just got finished installing a grounding system (dual ground rods to meet code) and a whole house EATON CHSPT2ULTRA Ultimate Surge Protector. Without me even mentioning it the electrician put a ground jumper on my cold and hot water pipes above the water heater.
As soon as we get a dry spell in the next few days, I'll fix my windows myself. None of the other things I wanted to tackle myself and both the plumber and the electrician used new technology such as crimped fittings instead of sweating pipes. I'm out some bucks though.
Man, that really socks. I never knew pex could be used from the service curb stop to the house. It does seem to create a ground problem.
As an entertaining aside, my dad was called out of town to care for sick relatives. My mom remained at home. I lived 30 miles north. My dad would call my mom each morning and evening. Landline. The morning calls had a terrible "hum". Afternoon calls had none. After a week, my mom called to ask for some help. I did some basic checks and determined that a big 4 prong extension cord that was deeply buried behind lots of furniture was the culprit. I unplugged it and the hum went away. Mom was happy. I didn't pursue it further. Weeks later, my dad returned home. Finding the princess telephone next to his easy chair lacked dial tone, he plugged the cable back in. The morning hum pattern returned. Dad decided to investigate. Hi pulled his big chair from the corner. A 4 prong jack/plug assembly connecting the Princess phone to the extension cord appeared "discolored". On investigation, the mystery was solved. Every morning the cat was going being the chair and pissing on the connector. The Princess phone has a lighted dial. The AC power for the lighted dial was coupled to the tip/ring by the cat piss. By afternoon it dried and the "hum" disappeared.
