Water Heater Pressure Relief Help

[IceIceBaybee]

Hey guys,

New to the forum, and hoping someone can shed some light on a small problem I am facing.

I want to have the discharge piping properly installed for this water heater in a 2nd floor condo (no floor drains of any kind). There is a pipe in the wall not connected to anything that I believe was used for pressure relief with the previous water heater, but it sits higher in the wall then the pressure relief valve on the tank. There is currently pvc running from the relief valve down to a 5 gallon bucket.

I want to know if it would be acceptable to use a shark bite line (as demonstrated in the photo), or if having things go against gravity is a big no-no. Any advice is appreciated.

Thanks!

Your pictures don’t show up in either of your threads. It says error when I click on them.

I tried to re-upload them. Did that work?

They show up now. You can’t run t+p uphill

Best situation to run into a 5 gallon bucket then?

Best situation is confirm that is the t+p line by hooking a shop vac up to it on blow mode. If it is, open the wall and lower the pipe to the proper height and connect to it.

Okay thanks

Why not elevate the water heater so you can use the discharge line properly (downhill stream)?

One reason you do not want to run uphill from the temp-pressure relief'valve is that released water can dribble back down and contribute to corrosion or other failure of the temp-pressure relief valve. Then, when it needs to release pressure, it might be unable to and lead to an explosion of the tank.
