I would stop taking these internachi classes.
Another person taking them said their video told him that due to energy requirements that tank heaters may explode in 3-5 years.
You are nuts!
I’m not nuts if they are teaching things that just are not true
That GUEST was trying to convince everyone to buy tankless water heaters.
I’m sure that is why but that Guest spot should of been edited out of the video, because the guy listening to the video believed it. Now we are off topic.
@kshepard
That is Kenton Shepard. He was just listening to the guy.
I tagged Kenton. Lets see if he chimes in on this subject.
guy listening to the video believed it.
The student who posted on forum
I’m done…
The discharge piping serving a pressure-relief valve, temperature-relief valve or combination valve shall:
- Not be directly connected to the drainage system.
- Discharge through an air gap located in the same room as the water heater.
Number 2 is king
They are all important.
I would stop taking these internachi classes.
What a ridiculous statement. Obviously new inspectors need to understand that when it comes to plumbing there are many different set of codes and they just need to understand the codes in their area. Honestly stay away from being a code inspector and just contact a local plumber with questions.
Thank you all for the replies. This will help improve my reports and knowledge
The size of the drain line should match the outlet size of the relief valve, and an auxiliary pan with a 1” drain line, which drains to the exterior is required underneath when the unit is installed at or above the level of the living area
Interesting, my area we can discharge to a a floor drain
- The local waste piping serving a water heater temperature
and pressure relief valve, water treatment device, cross connec-
tion control device or assembly, humidifier, sterilizer, or a furnace
or air conditioner may discharge into the riser of a floor drain
when installed in accordance with sub. (7) (b). - The indirect or local waste piping serving a water heater
temperature and pressure relief valve, water treatment device,
cross connection control device or assembly, or a furnace or air
conditioner may discharge to a floor served by a floor drain so as
not to create a health or safety hazard. - The indirect or local waste piping serving a water heater
temperature and pressure relief valve or water treatment device
may discharge through the cover of a clear water sump so as not
to adversely affect floats by means of a fixed air gap installed in
accordance with subs. (7) (a) 2. and (8).
And 7b is in reference to air gap hence why I said it was king
(7) AIR−GAPS AND AIR−BREAKS. All indirect waste piping and
all local waste piping shall discharge by means of an air−gap or
air−break into a receptor.
(a) Air−gap installation. The installation of an air gap shall
conform to any of the following requirements:
- The distance of an air gap shall comply with one of the fol-
lowing:
a. The distance of an air gap serving indirect waste piping one
inch or less in diameter and a receptor shall be at least twice the
diameter of the indirect waste piping.
b. The distance of an air gap between indirect waste piping
larger than one inch in diameter and a receptor shall not be less
than 2 inches.
(b) Air–break installation. The air−break between indirect
waste piping or local waste piping and the receptor shall be
accomplished by extending the indirect waste piping or local
waste piping below the flood level rim of the receptor and termi-
nating at an elevation above the trap outlet.
I’ve been doing this for 40 years and I’ve seen it done correctly many ways.
I like the put a bucket under it. Which in my opinion is just fine
This is in my report.
It may not be appropriate for your area. However, I doubt it.“According to present day requirements, water heaters should have a pressure relief valve and drain line which flows by gravity to the exterior, or downward to within 6 inches of the structure floor. The size of the drain line should match the outlet size of the relief valve, and an auxiliary pan with a 1” drain line, which drains to the exterior is required underneath when the unit is installed at or above the level of the living area. "
Wasn’t this one of the first changes to the 2001 FBC?
Most all homes, 80%, I inspect the drain lines goes thru the wall & terminates outside, like my home.
I’m saying before the FBC most all went outside. Therefore, homes pre-2001 no pans.
Pans are nice. I didn’t have one when I bought my house never had one in any other house.
Replaced heater put pan in happy. The old one discharged straight to the crawlspace.
I just shook my head. No shutoff valves improper flue filled with leaves.
Pans are required if the heater is at or above the living area.
Been that way for a very many years
