Drains require fall! American Plumbing, LMP #556

Our customer called saying that she was being told her main drain line was stopping up due to bellies in the line. Our video inspection showed her drain line did not have any measurable bellies but, that her drain line had no fall. The entire 90' drain line was only 17" deep throughout. There should be at least a 12" difference in depth from the initial inside cleanout to the outside marking.

What is a tempering valve? www.americanplumbingla.com #americanplumbing #geriatricgymrat #temperingvalve #federalgovernment #plumbingrepairs A tempering valve is a plumbing safety device that mixes hot water with cold water to deliver water at a controlled, safe temperature. What it does Reduces very hot water from a heater to a preset temperature Prevents scalding at taps, showers, or fixtures Keeps water temperature consistent even if pressure or supply changes Where it’s commonly used Domestic hot water systems (homes, apartments) Bathrooms, showers, sinks Solar and heat-pump water heaters (which often store water at higher temperatures) Hospitals, schools, childcare centers (where safety standards are strict) Why it’s important Water heaters are often set to 60°C (140°F) or higher to prevent bacteria like Legionella Tempering valves typically reduce outlet temperature to around 45–50°C (113–122°F), which is much safer for skin How it works (simple) Hot water enters the valve Cold water enters the valve The valve blends them to a set temperature Mixed water exits to fixtures Tempering valve vs thermostatic mixing valve (TMV) Tempering valve: Usually serves an entire house or group of fixtures TMV: More precise, often used at individual outlets (like a single shower)
