EcoRenovator - View Single Post - A7 AirTap install (ASHP hot water heater)

I had problems before with that Swiveling pex to 3/4" copper. (It's above somewhere).
Edit: It' on page 33.. http://ecorenovator.org/forum/geothe...heater-33.html

The pipe has to be 6" tall, so the A7 heatpump has some support on that side..
The support bracket clamps onto the 6" pipe.. A 6" brass nipple should be a drop-in install..

One mod I'm thinking of is to Shock-mount the clamp a little..
Maybe wrap some 1/8" rubber sheet around the pipe, under the clamp..
That might cut the vibrations a bit..

Home Depot used to carry them. I had one on my HD wish list.. They no longer carry the 6" version.
I think maybe I'm going to go for this 6" Brass LASCO 17-9501 3/4-Inch by 6-Inch Red Brass Pipe Nipple - Pipe Fittings - Amazon.com

At this point, it's time to try Brass.. I'm just wondering if Teflon tape is the best way to go..
Is there some sealant that works well and the pipe will still be removable later on?
