I have a Bradford White Defender hot water heater with power vent RG1PV50S6N. The physical L shape of our house walls catches nasty backdrafts that go up the 45 degree angle exhaust pipe and down into our basement where the hwh is located. This happened with our bathroom vent too in the soffit above and we put a backdraft preventer on that.
Is there anything outside at all I can do with the termination point to help? You can see my walls and vent attached. It is close to the ground.
I've been told by a few plumbers I should NOT do the "candy cane" type connection where the pipe comes out (seen below), goes up and then down 90 degrees because of possible condensation issues. It's confusing to me because they start talking about my system probably wouldn't do that but if it did there would be acid and that needs a separate drain, etc.
I can't install a damper on the pipe inside myself and would be a bit scared to go that route because if it ever fails or gets stuck, burnoff could backup. In theory the Bradford White shuts off if that happens, but that "in theory" could get me killed.
We looked at something like this from Amazon to expand to a 3 inch vent, but it would be frankensteined together outside to make it work. https://a.co/d/dCJVn7q
I asked Bradford White and they said there is nothing I can do because my exhaust doesn't go through the roof.
I guess if there is no outside solution, if there was an inside damper that could go in the pipe with an indicator about it opening correctly it would give me piece of mind.
Thanks.
