Keep up the great work man. I’ve learned a lot of helpful tips and also great examples of proper installation. Especially with venting. From watching your videos.
Yeah idk they are heating up the water twice. We typically feed cold into the first heater then feed the second heater with hot water. The first heater is set around 90 and the second is set at 120.
In my area it’s required to put the tee for expansion tank in between the shutoff and heater. This way if the water heater is isolated the EXP tank can still service the unit. Do you have a different code in your area? Just curious
Those 75 gallon tanks are monsters. We took one out that was a commercial unit a few months ago and it broke the bearing in our commercial dolly rated for 1200lbs.
Not really a reverse return. That would require a third pipe. Reverse return doesn’t make a lot of sense with only two tanks. This is piped as parallel connections and is well balanced so the flow will split approximately equally.
Hey Bill, I appreciate the comment from somebody who appears to have some knowledge of the plumbing industry. However, we are copying this directly from the Bradford White website. We put a slowing of the PDF on our website. kcwaterheater.com/water-heater-piping/
I know you think you’re adding valuable input, but you are not. We are following the diagram from Bradford White. We have many other videos showing the actual chart.

Finally a real plumber hard piping water heaters
Thanks Sam.

Educational. Thank you.
Glad it was helpful!

They do not require that here, many cases you don’t have an option to properly support the expansion tank when it’s right off the tank.
@ we still run the exp tank at least 18” from heater and support it it’s just tied in under the shutoff
We do that in a lot of cases too.
@ well you guys do awesome work. Thank you for posting online
I thought you needed check valves with that type of system
No check valve required. A check valve is shown in most diagrams so they can reference the relation to the thermal expansion tank.
I think you right....?!!!
How about 1- 75 gallon 76,000 BTU with a thermostatic mixing valve

You’re supposed to equalize the cold and hot lines
