i always run copper or pvc because that is what was used when i used to do plumbing. i have used shark bite fittings when replacing water heaters but sometimes they don't seal well so i would rather just solder in new copper. my favorite jobs, when i did plumbing professionally, were the commercial jobs that were 100% copper supply lines. solder just looks so nice and is easy to do.
even building supermarkets and hardware stores were supply lines were 2" and larger, with a good burner and a larger gas supply tank, you can get beautiful smooth solder joints that just make the lines look so nice.
when i moved the smaller water heater from upstairs and put it down in the garage under the bathroom, i ran everything in pvc and copper. you are better using cpvc on the hot side of hte water heater though because pvc can soften and come apart right above the outlet for the hot if the water temp is set to high.
last night we spent the whole day after work at the dealership. my son found a 2022 xlt f150 that looked like it was owned by an older couple. the truck was spotless inside and only 2 tiny chips in the leading edge of hte hood from rock strikes. the underside was spotless, the tires were very nice, the bed looked like it was never used, and the interior looked brand new.
the salesman said an older guy brought it in because his wife had a hard time getting in it now and they got a lower van.
so we drove it and liked it. the carfax showed all maintenance was done at the local ford dealer and on time for the mileage in the book, even diff fluid changes so that made me think the older fella story was right since younger folks generally aren't particular about following the maintenance properly.
the truck has so many packages on it. tech, convenience, tow, chrome, it has so much junk on it that i was even impressed.
anyways, my son got it. my wife told them he wasn't paying over 30, period. no 30 plus ttl, 30 was all or it was staying with them. they tried to balk and say this and that but in the end, she got it for 30 out the door and zero down. i feel its a good deal since hte truck looks like it came off teh showroom floor.
its funny whats acceptable for prices on vehicles now days. 30k is hte cost of a new truck, to me, but i know its really not. its just so crazy to think used costs so much
