are "Frost free" hose valves a scam?


It requires a metal feed pipe to conduct room heat at least as far as the valve seat to prevent freezing. [Assuming that water does not collect in the open section of pipe beyond.)

Alternatively, yes, have a big void in the insulation around the valve unit so warmer inside air can get to it.

Similarly, if you had an ordinary hose bibb and put one of those styrofoam cups over it in winter, it requires metal piping to supply some heat.

Generally, pipes in exterior walls are better off with no insulation between them and the interior. For example squeeze insulation batts behind them rather than cut slits in the insulation for the pipes to nestle in. Or cut V trenches in the insulation, as wide at the front as the pipes are deep, following the routes of the pipes.

Power tools are usually not damaged by one soaking if you let as much water as you can drip out promptly and allow several days for any remaining moisture to evaporate before using the tools.

Called a plumber and he's coming over tomorrow. He said he's been replacing a lot of these lately. Guess it's good to know I'm not the only one with issues.

We had a hot/cold/hot/cold type winter this year so said snow would melt, freeze, melt etc so there was always some water accumulating in there.

Something does not make sense here. The washer/seat assembly is inside the house. It was stated the leak did not start untill the valve was opened which would indicate to me the leak is on the downstream side of the washer/seat assembly. During the winter/cold weather there should be no water in this section to freeze. If,as you state,snow was melting and getting in there then the valve must not drain downhill very well allowing water to be trapped in there. That is the whole theory behind how these work. I don't think the insulation had anything to do with this as if that were the case the leak would have been in the washer/seat area or further upstream which would have shown up at the first thaw. Did the pipe rupture outward or inward? I am suspecting something in the mounting/install method may have contributed to this

It wast mostly just a speculation. Perhaps during blizzards snow would get in, and because it's not liquid it would sit there, then next day it gets hot it starts to melt but does not melt completely because it gets cold again by the time it drips out, repeat this process 10+ times (this is how our winter was) and you have many accumulated layers of ice inside.

I'll ask the plumber what he thinks when he sees it.

Perhaps when you installed it, the frostless sleeve was running uphill, this will trap the water in the sleeve, I believe they have to run down hill from the connection to the hose connection outside to allow the water to drain out.

So I got it replaced, he had quite a lot of trouble getting the old one out, I never intended it to move when I installed it lol. He added a valve with drain plug, so I'll just have to be sure to drain it in fall.
