Excellent course, Enjoy!!
Hi Pat,
My name is Carmen and I’m a student also at InterNachi pending to become a home inspector soon. Now, here is the question. We have in the garage installed a pretty similar water heater as this one in the attached pic. The water heater is also electrical supplied and is raised 18" above the floor. Now, this installation 18" above floor level can only be required by the State construction codes. It’s got no objective in case of electrical water heater, which do not have an open combustible source. Is that correct? Also in the course I’ve done says that only the open combustible source water heater should be installed 18" above floor to prevent ignition of the vapors in case of combustible fluid spilt on the floor.
I’ve started the video! I’m anxious to inspect our own water heater after eating this video.

Have fun and pay attention to the video content, the questions on the exam will reflect on the video.

Thank you Scott, the video was very informative. I picked up a lot of valuable information! I’m ready for the exam! Thanks again.

Watching the video and taking pics of the water heater next.
In my jurisdiction expansion tanks are also very rare. They are only required if there is a check valve on the main water line (creating a closed system). With no check valve the expanded water can flow backwards down the main water line and not built up excessive pressure.

I have a question about water heaters. My whole neighborhood was built around 2011 and all water heaters were installed with a Pressure Relief Valves instead of an expansion tank. Is this a common practice? Also, the TPR valve is vented via piping that discharges to the outside along with the other PRV. Location is NW Florida.
Nice one! I’m glad mine isn’t installed like that - with PVC even. Yuck!
I’m looking forward to this course. I see some really great posts on here, thanks!
Joining the course. I see some great photos and descriptions.
ready to start another course
The TPR valve is required for safety. A thermal expansion tank is additional component and may or may not be “required”. The expansion tank DOES NOT REPLACE a TPR VALVE (sorry for shouting, I really want you to see that).
I would ask the jurisdiction inspector (county?) what they require and if the discharge point is acceptable. They’re usually very happy to share info, educate the public, etc. A plumber should be able to answer as well.
Late reply here, maybe redundant. The TPR valve is missing an extension tube. It should discharge close to the floor for safety. It’s an easy and inexpensive installation (unless an actual plumber charges for it) but an obvious safety hazard. Good luck, I hope you can figure out how to make your camera focus better, mine struggles at times too…
Water heater tanks course time for you! Others are saying it’s a good course, here we go.
