Inspection & Writing Assignment:

When doing an inspection, one of the questions you need to answer is, is it sewer or septic? The inspection is a very limited visual inpection. Unless you offer sewer scope as an added service. I'm not sure I want to offer that.

Research & Writing Assignment:

Plumbing is a complex part of the house, there are many things to consider. The specific vents and sized plumbing for all the different components is truly amazing. The fact that you have a size diameter pipe with a limited distance to prevent siphonage is impressive. As for trap seals, I never knew the importance of them, until now.

Inspection & Writing Assignment:

The plumbing under this kitchen sink is pretty good. The sink's tail piece and drain are 1 1/4" and not 1 1/2", the electrical receptacle for the dishwasher and disposal is not GFCI protected. There is a high "S' loop entering a 1 1/2" ABS. There is an air gap present and it appears higher than the rim of the dishwasher. The flexible water lines are braided steel. Shut off valves to both water lines are present. There is a lateral PVC pipe connected to the ABS via a slip connection and terminated into the disposal. No signs of water leakage were present and the sink drained acceptably.

I have yet to see a gas line drip leg installed down stream from the gas shutoff valve to a gas forced air furnace. It obviously is the better way to install the gas line drip leg. Things that make you go, Huh.

Inspection & Writing Assignment:

When I was inspecting the Food Waste Grinder, I was able to identify that the device is not properly operating when turned on. A particular noise when turned on, suggest that something is stuck in the grinder teeth. Evaluation by a Professional Plumber is recommended.
