Same goes with the electrical fixtures and wirings, which are often embedded in between double walls or embedded in concrete. Backflow prevention devices should also be carefully considered, since this helps prevent any untoward flooding in the event of plumbing and waterline leakage.
Basement bathrooms and laundry tubs are sometimes also missed out in the process because not all homes have these areas and fixtures in their basements. Dryer vents, on the other hand, should also be considered for which standard length of dryer vent hoses should not exceed six feet in length. Another important consideration should also be electrical grounding, since improper grounding could cause major problems from accidental electric shocks or even cause house fires.
Unapproved or substandard flexible gas connectors, valves and uncapped gas lines, which should also be of paramount concern since the slight indications of gas leakages can be tragic and disastrous. Also the same with indoor furnaces not properly operating or is not functioning properly. This should also be checked since problems could range from gas leakage to defective firing systems that could also cause a house fire if left unchecked.
Lastly, make sure that water heaters are installed properly or pressure release valves must be working properly or the important copper run off device that should always be checked, as the same with garage door openers or extension cord wiring being used as permanent wiring for fixtures.
So these are the areas commonly missed out by home inspectors so make it a point to also have these in their inspection checklist, it is for your own safety and security.
