Household water heater

This is a pretty cool video explains how an expansion tank function.

I shared this video with yicheng how to install an expansion tank.

We consider replacing the anode rod and this video provides very good tutorial. It seems simple, but to screw it back can be very difficult. Sear also provides detail instruction as well.

It turns out that we need to replace the heating element from this (videos) but the themorstat seems fail so we want to test the thermostat.

To replace the heating element, we follow this video. Again, nothing works easily as the video shows. In our case, we have hard time to screw the element back.

Household plumbing

There has been a lot need to document, it seems that I need to start this part.

First of all, household main water shut off.

There are two main water shut off:
The first one is located by the meter and it needs a special tool to shut it off.

The second one is normally located inside, this video provides plenty of details.

Here some of the fixing videos

The second one is normally located inside, this video provides plenty of details.

Work on RAV4

My RAV4 is almost 4 years old, and it could be the time to start working on it with any error!!

Firstly, I found TPMS light on, after inflating all 4 tires, the light stays on!

Here, I find a forum site by Sam Leman on Toyota. Of course, it covers my RAV4.

Here are some ways to reset it:

	
  • Drive at or above 50 mph for 10 minutes. This can cause the tire pressure sensor to reset the next time you turn on the car.
  • With the vehicle off, turn the key to the “on” position, but don’t start the car. Hold the TPMS reset button until the Toyota tire pressure sensor blinks three times, then release it. Start the car, and wait 20 minutes for the sensor to refresh. The TPMS reset button is usually located beneath the steering wheel. If you are unable to find it, refer to your vehicle’s owner’s manual.
  • Inflate all tires to 3 PSI over their recommended amount, then deflate them completely. Be sure to include the spare tire, as it may have a sensor as well. Once they’re all deflated, re-inflate to the recommended tire pressure.
  • With the vehicle off, disconnect the positive battery cable. Turn the car on, and honk the horn for about three seconds. This will discharge any power still stored in the vehicle. Then, reconnect the battery.

    Basic component

    Details on a switch relay by JumperManTech.
    Understand the transformers and coils used in  HVAC system. Unfortunately, he does not do a good job. He has the knowledge but he jumps around and does not treat the viewers as students.
    

    Information on how to wire a 240V/50A onto the panel

    How to remove a breaker from the residential electric panel. This guy also explains the danger of mis-handling.
    There are people posting videos with least information, it could be misleading and we batter watch out. 
    A pretty decent tutorial on adding a new breaker, I liked his video. This guy also has a video on install a sub-panel, he is really good at this type of work!

    Okay, after doing all the research, I would like to work on this project and get a NEMA 14-50 outlet wired for my Tesla Model Y.

    Need to purchase parts

    	
  • NEMA 14-50 outlet, receptacle. According to this guy, I decide to buy a Hubbell 9450A for this project from Amazon. It is $147 now and I found a cheapter option from Kelly & Hanes. Here are some detail specifications of this outlet: HUBBBAE00255_A44 HUBKELE07290_1
  • A 50 amp breaker that matches my home electrical panel.
  • Wire. Romex 6/3 wire is suitable for this project, I need to measure the length.
  • Conduit. If I can wire it inside the wall, it will not be necessary
  • Other small components
  • Videos pertain to Tesla in particular
