Heres a crude diagram.
That's the floor run of 1/2" pvc for my HVAC condensate drain. The furnace has trap at drain exit.
I tee'ed into the run of pipe on the floor gave a second opening to drain my water heater condensate into. Is this incorrect?

personal preference:
run the heater drain parallel for servicing / blowing out purposes
however
what you did is minimally acceptable

Please elaborate, why is it only minimally acceptable?
What I am concerned is that having that tee and the extra opening (street 90 with rubber tubing inserted) would effect the flow of condensate from the furnace.
I have gotten no condensate from the w/h, but it isn't winter yet...

You are talking about condensate and not the relief valve and if so where does the relief drain?

condensate lines often grow 'algae' internally and may clog
if they are independent - easy to service with some bleach and a 'puff' of air
when tied together the 'puff' may go the other way and NOT clear the drain
imo: run 3/4"independantly
however
I have seen much worse which still 'works' - until it does not

Plumber Dan-- yeah the condensate. The temp relief doesn't matter, its an unfinished basement and is piped to the floor.
Thanks though for the other post... I meant to say it is 3/4"... so what about that extra opening, does that act as a counter to the other vents or something? Will the furnace condensate not flow as freely now that there is another opening at the water heater?

it will flow just fine
it 'should' never be more than 1/16" full (if even that)
the only issue is serviceability 'down the road'

You are talking about "condensate" so there is really no "flow" and so they do not conflict with one another.
