Thank you for all your inputs!!

I like idea someone mentioned of putting rock base to control dirt and create easier drainage.

Update; my system not under negative pressure when blower kicks on When I pop cap off just above shutoff valve. I get static air flow from enclosed pressurized air handler box. System under pressure I guessing it backs down drain pipe? IMO the S/P trap to prevent outside air positive or negative and insects backing up into air handler? Why else? there no sewer gas problem?

The condensate pipe you installed may be too close to your heating flue pipe. The original pipe had a good clearance from the flue pipe generally ranges from 1 inch for B-vents (double-wall) to 6-18 inches for single-wall pipes. PVC melts around 212-250°F,

I flush out my condensate pipe I use 1, 6 oz cup of bleach in 1 gallon of water and flush the line, you should be able to see water flowing out where the line terminates outside.

I’ll keep eye on it see if turns brown? Got little more than 1/2” the old 45 degree elbow had about 1”. The angle you see in picture not straight down so it looks closer than it is.

When I hook up garden hose using supply water below the cut-off valve I see gusher coming out at outside drain by A/C.

From the Carrier website:

Step 4 - Clean the Drain Line
Once the AC drain line has been unclogged, the technician will likely follow up with a thorough cleaning of the drain pipe using a commercially available cleaner designed for use on PVC piping. If you ask, the technician may show you how you can pour a cup of a mild cleansing agent like distilled vinegar to occasionally give the drain a cleaning yourself between routine maintenance calls.

This is relative to a follow-up after a technician cleans a clogged drain line. The Carrier website also says:

"Yes, you can pour hot water down an AC drain line to help clear minor clogs. The heat can help dissolve and loosen any buildup in the line. Turn off power to your AC unit, locate the drain line, and slowly pour a small amount of hot water down the drain line. Avoid using boiling water, as it could potentially damage the pipe or fittings. If the clog persists or if you’re unsure, consult a professional HVAC dealer for a more thorough inspection and cleaning."

But, I guess it all depends on who you ask. I asked Munn's and their current recommendation is to use hot water only for routine maintenance.

I would just use Top Job, Mr. Clean, Janitor in a Drum and call it a day.

This is what I ended up doing if anybody cares! The condensate line automatically goes below ground, but I chose to keep it uncovered. I redid the same configuration with fresh pipes, added a screen to the venting, put some gravel under the pipe and built a little stone wall around so mowers hopefully don't run over it!

You may have the most beautiful condensate drain in The Villages.

Update;

Ok my heat finely kicked on. I took temperature of vent conduit duct that 1/2 inch away for my altered drain s pipe. The metal flex conduit heats up to 80 to 84F, check it several time till furnace cut gas off when desired temperature was reached in house. No browning hot spot on S tube.

This is true. My new house had unglued fittings right off the AC unit. The water pooled and leaked into a closet. The first time I called I was told welcome to humid Florida, but the second time they came out and fixed it (along with restoring the trim and drying the closet).

I watched installer install mine was completely ran from outside to air handler, no connection only at cut off valve and above and out where pops out of ground by a/c unit so not problem for me. But, can’t say others do good job like Munns.
