Daughter’s iWatch 3 won’t charge. Repair services exceed value. Will probably disassemble it because what’s to loose?

An 8-port PEX-A manifold (that’s made from (2) 4-port manifolds). Ea w a quarter-turn shutoff valve. The 8th port is a spare and is capped off. This is for hot water and so the PEX pipe is red. Where the pipe bends sharply 90 degree brackets are used. The manifold is adjacent to 3/4” copper hot water line and is currently held in place with Ty-wraps. 4 ports go left and 4 ports go right.

had time this wkend to work on time-to-hot plumbing proj. Converting 3/4” copper trunks to individual 1/2” PEX-A. the 7 individual runs are in place & are terminated on the manifold. Next I’ll tie in the manifold to the 3/4” copper from hot water heater (manifold currently held in place w ty-wraps)

Daughter said he jeep’s rear defroster stopped working. We discovered one terminal had torn off the horizontal conductive silver(?) buss. We cleaned both surfaces and successfully soldered it back together. Win πŸ†

I had some time this afternoon to work on my basement plumbing project. Ran (3) 1/2” PEX-A pipes from manifold to east side of the house - kitchen sink, dishwasher, washing machine.

Repairing a refrigerator ice maker

Helped daughter diagnose her refrigerator’s ice maker. Her model has a dedicated evaporator for the ice maker. A fan draws that cold air over the ice cube tray. That fan malfunctioned. We tested it on my bench. New fan from digikey.com $15, delivered. Some appliance part sites wanted ~$100+

Nice. I’ll try it next time I’m in that situation. But also it’s a reminder that the assistant can help in lots of ways

Homemade/custom PEX-A hot water manifold. It has two 4-port manifolds cascaded together. One is pointed to the left while the other is pointed to the right, which maps to the fixture locations, half on one side of the house, half on the other side of the house. All eight ports have a quarter-turn 1/2” PEX-A shut off valve. One end of the manifold is closed, while the other hand has a couple of 3/4” copper fittings that will adapt to existing hot water copper.

Making a hot water PEX-A manifold - so I can remove long 3/4” copper runs and use 1/2 PEX instead. So fixtures get hot water quicker. Math says 3/4” copper ID versus 1/2” PEX ID is a ratio of 2.7 to 1

Helped install a combination washer dryer. On a kitchen. Because the gal can’t reasonably access the main laundry in the basement. Brought in hot cold drain and electric.

Oh wow. Back then my son happened upon a promotion where he’d earn points when he used a new browser (Bing). He’d redeem points & receive Microsoft hardware in the mail. Game controllers, mp3 player (zune?), Bluetooth headset, etc.

As a suspicious parent, I asked WTH he’s receiving gear for free?!

Replaced the main bearing in our clothes washer. Two steps were difficult:

2) separating/removing drum from main shaft

I’m currently testing it. No weird noises nor leaks so far .
