Inspection & Writing Assignment:

Water heater;
Another component of a home that you might inspect is the water heater. Find the tank and and take a look at the TPR valve and the general condition of the fittings and the outside casing. Look for leaks, corrosion, a pan underneath, straps on the upper and lower third of the tank and a pipe off connecting to the TPR valve to take away the discharge to a location that is proper to city, county, or state specs.. Look for the label. Note the date, manufacturer, and model number. You might also go into deeper detail of your inspection but at this point the check list gets really detailed.

Not my picture. For illustration purposes only.

Inspection & Writing Assignment:

When inspecting a water heater, it was noted the TPRV was not installed properly, it was not within 6 inches of the floor and terminated into a bucket. the bucket would not be a proper drain for discharge. The pan drain did not have a drain to an appropriate discharge area. It was recommended to have licensed Plumber to repair.

Research & Writing Assignment:

This is an excellent course to refresh most Home inspectors on the requirement of combustible air requirement for Gas water heaters in a confined area. Often found in older homes. I do believe an update for protection for water heaters in the garage area such a Bollards should be added.

Inspection & Writing Assignment:

The attached pic shows a newer water heater installed in a basement. This water heater does have a gas shutoff valve installed (and a drip leg). The drip leg and gas shutoff valve are installed in the correct sequence. The tank is lacking a water catch pan. There are two 2-inch straps installed to prevent the tank from tipping during an earthquake. One strap should be installed at the top third of the tank and another at the bottom third with a minimum of four inches above the controls at the bottom.

Research & Writing Assignment:

The drip leg for gas water heater gas pipes should be installed between the gas shutoff valve and the water heater. Drip legs are used to catch and remove debris, rust and/or condensation in the gas pipe. Water heaters with an insulated blanket on the exterior can void the tank warranty.

Inspection & Writing Assignment:

General Topic: Building Component Essay
Specific Topic: Crawlspaces- Is an unvented and unconditioned crawlspace a deficiency?

https://education.nachi.org/show.php?course_id=46&element_id=7293

After taking this course the answer to the question posed seems clearer to me. At issue is not only whether to vent or not vent, but whether to condition or not condition as well.

A vented crawlspace performs reasonably well, so long as vapor barrier is applied on the soil, the floor joists are appropriately insulated, and the plumbing and any ductwork is appropriately wrapped and sealed.

An unvented, foundation-wall-insulated crawlspace, even with vapor barrier properly applied, stands to see moisture levels that are unable to be, or difficult to be properly mitigated.

But an unvented crawlspace that is treated as an interior room to the home (or a mini-basement) may indeed be the very best solution, eliminating the need to insulate ducts or plumbing, reducing the production of condensation and therefore moisture content, and creating a better barrier (insulator) to adverse exterior temperatures by conditioning the space beneath the first floor.

Research & Writing Assignment:

General Topic: Essay Re System or Component Within Course
Specific Topic: Roof Components at Concave Slope Transitions

The roof slope transition should offer a visible flashing that assures resistance to water intrusion as water sheds from the upper slope plane. But it requires more than just this. The layers in order of installment for this transition, beginning with the layer closest to the sheathing are:
1. The required/area-code-designated width of ice barrier above and below the roof slope transition (roughly 36 width, installed 18 each side of slope transition),
2. Underlayment on the lower plane below the transition, which extends at least 4 above the transition,
3. Roofing covering material laid up to the roof slope transition,
4. Metal flashing material that overlaps the lower underlayment by at least 6 and extends above the transition (over the ice barrier) at least 6,
5. Underlayment on the upper plane above the transition, which extends at least 4 over the metal flashing,
6. Roofing covering material that begins on the upper slope plane, just an inch or so above the slope transition.
When installed properly, this six-course layering assures resistance to water intrusion as water sheds from the upper slope plane, onto the lower slope plane.

Research & Writing Assignment:

TPR Valves and Discharge Piping. TPR valves are important safety devices on water heaters. They allow water to discharge when either the safe temperature or safe pressure are exceeded in the tank. An important component of the TPR valve is the discharge piping. The piping must allow free flow of water from the valve to an air gap in the same room as the water heater.
