Dan Holohan: How to set a pressuretrol | 2020-05-13

If you have a steam boiler you're also going to have a pressuretrol. I've always liked that word because it's a marriage of the words pressure and control, both of which have much to do with our older steam-heating systems. Pressuretrols don't come with screwdrivers, but most contractors already have their own screwdrivers, so that's okay.
