Suburban Pressure Release ???

The pressure release on my Suburban has a threaded outlet, but is turned to the 4 o'clock position and ports into an aluminum exhaust shield.

Have any of you turned the pressure release to the six o'clock position and run a threaded copper discharge pipe down and out of the access door?

I haven't yet attempted turning the release for fear of damaging the threads or breaking something causing a leak. Just curious if I should give it a try?

The T & P valve has pipe threads.

Pipe threads are tapered and the tighter you screw them in is how the threads seal.

If they are sealed at the 4:00 position then turning to the 6:00 position "PROBABLY" won't hurt unless it was turned 'excessively' tight to get to 4:00.

Why not screw a threaded, barbed nipple into the T&P and run a piece of plastic/nylon/braided PVC hose to wherever you want it to drain?

Does it drip or why do you want to drain it to a specific area?

Thanks for the input and plumbing knowledge. I like the barbed nipple and braided PVC idea. I occasionally release the pressure during maintenance routines but in general prefer not to port water into the device even though I know it's a design feature.

Very helpful suggestion!
