Connectors should be used to connect an appliance and equipment to the vertical chimney or vent, except were the chimney or vent is attached directly to the appliance. The vent connector should be as short as practical, and the appliance should be located as close as practical to the chimney or vent.

Hot water is defined as water of a temperature of 110° F (43° C) or hotter. Tempered water ranges from 85° F to 110° F (29° C to 43° C), and the device supplying the tempered water must limit the temperature to 110° F (43° C).

Crawlspaces

Access openings must be a minimum of 18 inches high by 24 inches wide. Access to all under-floor spaces must be provided with access openings through the floor not smaller than 18 inches by 24 inches (457 mm by 610 mm).

Hydrostatic pressure refers to the pressures caused by water pushing against slabs and foundations, particularly underground concrete block or poured concrete walls of foundation and crawlspaces. Water is dense and weighs about 60 lbs. per cubic foot of volume and is therefore capable of generating immense hydrostatic pressure on anything that restricts its natural movement or flow.

The weight and pressure of the dry soil may affect and crack a foundation. There is wet soil that can exert a force against a foundation.

Collar Ties

Collar ties span between and connect opposing rafters, and they are typically placed in the top third of the attic spaces. Collar ties hold the rafters down against the ridge board and, to an extent, help prevent rafter spread. Home inspectors should take note of attics without collar ties, especially where the rafters run perpendicular to the joists. Collar ties must be at least 1x4 (nominal) and spaced not more than 4 feet on center. A lack of collar ties may allow roof rafters to separate and cause sagging of the roof's ridge and structure.www.nachi.org

A crack that forms a V-shape may indicate heaving. The illustration above shows a V-shape open crack in a foundation wall indicating heaving from the ground under the foundation footing. The ground in the illustration is expanding and pushing upward on the footing and foundation, causing a crack. This observation by a home inspector would be reported as a major structural concern and defect with correction and further evaluation & repair by a licensed foundation contractor or structural engineer

A brick wall is not necessarily considered to be waterproof. Water can penetrate through a masonry crack that is hairline or as small as 1/100th of an inch (0.3 mm). And masonry exterior-covering materials (siding) is porous and can absorb moisture during a weather event.

nearby vegetation

The inspector is required to report vegetation growing near the home according to the Home Inspection Standards of Practice. The home inspector should note the existence of any trees near the home, because the roots may affect the foundation or underground drainage pipes. Plants growing next to a house could raise the soil level too high against the foundation.
