ONTARIO, CALIFORNIA — What’s behind the wall and can it get you in trouble? If it’s an old shower valve, it might. That was one of the many issues debated by members of the International Association of Plumbing & Mechanical Officials Green Technical Committee meeting here in August.
Can a shower valve become a future problem?
The group debated mechanical retraction devices for swimming pool covers weighing over 40 pounds. They discussed pipe insulation requirements. They discussed which standard should govern drain water heat recovery devices. They discussed what the opportunities would be to recover waste heat from steam boiler blowdown.
