What do you guys do with the washer and dryer faucets? Anyone ever had them to freeze up?
What I did in February 2021 when it was stupid cold, I cut my hoses and let them drain into the stand pipe
Mine are on the outside wall on the north facing side.
Another option...get you a
electric radiant heater (only an example) and pull out the washer a couple of feet. Set your radiant heater on low and aim it towards the wall that houses the plumbing. That way your warming up just that centralized location and not an entire room. The insulation is (should be) on the back side of the pipes, so you're keeping your side of the wall warmer than the cold side. The plug your washer uses is a 20 amp outlet, so it should easily handle that heater even on hi. The heater that is linked, has a 250 watt option (low) which should be more than enough warmth to keep that wall warm for most of our winter problems.
Here's what we did for the apt complexes I worked at. Works most of the time, until you lose electric...then your jacked.
Under sinks, a clamp on light fixture with a 75 or 100 watt incandescent (old school) light bulb. Close the doors to create a heat tent under the sinks. Some times we'd drip them as well, depending on how cold it was going to be. You can also use this in the laundry area, but it's not nearly as efficient.
We put the radiant heater in the vacant laundries because they sit on the floor and the heat rises up the wall, keeping everything toasty. Use caution, you can scorch your wall using to much heat! Just keep it from freezing is all you need.
In smaller bathrooms, we would put a small
Electric Space Heater and close the door to create a hot room and leave the cabinet doors open so heat can get in there. This warms up the space to keep the entire plumbing system in the walls warmer than the freezing temps outside. It doesn't have to be HOT, just warm enough to keep the pipes from freezing. For the most part, our ideal temp was 56-60 degrees to combat the cold outside temps.
My old boss was an engineer who owned several apt complexes. When you're footing the bill for hundreds of empty units and trying to keep the pipes from bursting, you want to do it in the cheapest and most efficient way possible. This is the best we found. He would make us check temps through out the nights and adjust as needed according to their data. That was a bunch of BS, but for the most part, it kept everything from bursting. Winter storm Uri was a whole different beast. Hope this helps and remember it for the freezes to come. The only times this DIDN'T work, was when we lost power or the heater quit working. In my 12 yrs there, I lost 2 pipes in 2 bathrooms, because the heaters quit working.
