winterizing the outdoor faucets
Much of the piping in the Dallas area is not able to receive these long-stem freeze resistant hose bibs. Maybe yours is, but maybe not. The threaded fitting must be way back in the wall on the inside of the insulation in the heated zone. And unless the valves go into a basement I wonder how one checks for leaks when installing a new one.

I also notice that the more expensive of these are described as "quarter turn" which almost certainly means they are ball valves. Ball valves are great as an on-off valve, but are not good for metering, i.e., adjusting flow through a range.

I installed quarter-turn ball valves at our house the last time I replaced the two outside hose valves at our house (in Dallas), but the ones I got are too hard to turn to use easily. These were good quality "garden valves" made in Italy, but were a mistake for this use. I am going to have to devise a longer handle for them. Everbilt 3/4" garden valve. Our hose piping comes out of the ground and not from the side of the house.

In cold weather I disconnect the hoses and cover the faucets with insulation and a plastic flower pot. Probably you could just supply your tenants with a foam cover that is secured to the faucet with a clip or a rubber band.
