Tankless water heater manufacturers recommend flushing every 6-12 months. This is especially important in areas with hard water, as minerals can buildup inside the heat exchanger and cause performance problems. I'll run down the basics and I've collected the descaling instructions from the three main manufacturers of tankless water heaters: Takagi (sometimes labeled A.O. Smith), [...]
Since 1993, photoelectric sensors (aka photo-eyes) have been required on garage door openers. The CPSC recommend this change to "reduce the number of deaths to children who become entrapped under garage doors with automatic openers." I'm not saying it's a coincidence, but after watching Indiana Jones roll under that temple door in 1981, it pretty much [...]
While it is commonplace for property inspectors to note the electrical service size and often the size of the main water supply, the size of the gas meter is frequently overlooked. If a gas meter is undersized, the attached gas appliances could be starved for gas - especially when the major appliances are running at the same time. [...]

Aerators will come with different gallons per minute (GPM) flow rates that are usually stamped on the side of the aerator. Over the years, the maximum flow rates have [...]

Until the early 1980s, most toilets used 5-7 gallons per flush. Toilet technology has progressed (with a few mis-steps) to the point where ultra-high efficient toilets are available today that use only .8 gallons per flush. That may look like a typo, but companies such as Niagara Conservation have developed toilets that conserve water and [...]
The guardrail / deck connection is a critical element of deck design, but until relatively recently, the design of this important connection was left up to the whims of the contractor. Why is this important? When people gather on decks, they inevitably congregate along the guardrail, to enjoy the view, take some weight off, or [...]
When you learn that a water heater is backdrafting, it may not be self-evident what that means. I must admit that home inspectors can be guilty of using overly-technical language at times, and in the spirit of clarification, here is a description of water heater backdrafting and what it means to you.
