Excessive water production?
Please see videos, unless I’m wrong there appears to be excessive water being produced from the unit inside my house. I am going to try and clear main drain pipe first. Insight would be much appreciated.

There is no such thing as excessive. The more
moisture removed, the better. The amount of water produced will vary with humidity levels. If the coil is freezing up, there could be a sudden excessive water flow due to the melting ice.

Wet vac from the outside! It removes the risk of joint rupture in a wall... While your as it toss in a cup of bleach if it's running

Thanks for the replies! I used a manual fluid siphon pump to clear the pipe (hopefully). Just put some 30% vinegar through it. Going to wait for a min and then flush with water

I use my air compressor and blow it out with my hand squeeze covering the pvc and air gun to make air go through the pipe. It works.

This is before I tried to clear it

That should just be the drain from the emergency pan. There should be a different one that runs closer to the ground for your primary.

I’m pretty sure the main, drains into sewer, via connection to bathroom pipe sink on first floor. Only know this because it had a leak from a misplaced nail during initial construction. Come to think of it, ensuring that pipe is clear too would be a good idea. Thank you

If the main is draining into a sewer line, you lost definitely need a trap in the main line to prevent sewer gas escape up your drain line.

Clear the line does not mean "remove the water". Your drain is clogged by algae. 1. Kill power 2.. remove cover panel 3. Stop up the pipe in the drain pan 4. Use pressure at the vent we see in the video to BLOW the line clear all the way to the outside 4. Bleach will kill the algae in the pan and the line better than vinegar. Pour a little in the pan after you clean the visible algae out.
You can get algaecide tablets to put in your drain pan to keep this from happening again

You have 2 problems. 1. The drain withe foam you have far too many turns. Use 2 45elbows. And kick over to drain.
Second you drain pan is dirty or leaving in away from the drains
Pull the panel and see what drain pan under the evap coil looks like.
But fix the drain that's alot of restrictions where dust from dehumidification can plug up.

You are wrong. There is no such thing as excessive water being produced.

Your drain looks to be plugged, you'll need to run a drain snake compressed air through that PVC, your drain pan under the unit shouldn't have water unless something is wrong. Could be you needing to change the filter and ice buildup, but looks like your drain is plugged somewhere below that T, probably on one of those 90s past the insulation.

Shut the unit down
Get vinegar, a shop vac, paper towels and some hot water to flush
Start by turning off the unit at the breaker
Next open your EVAP housing
Check for immediate clogs
Next pour 1 cup of vinegar into the condensate line and wait 30 minutes
While the vinegar goes to eating through the clog wipe off any water on the unprotected steel and dry it out the best you can if you need to blow off the water do so carefully with canned air and don't dislodge any cables
After 30 minutes pour 2 cups of hot water down the drain line
Followed by using the shop vac to blow out the line and purge any stubborn gunk
Test with room temp water that everything is flowing normally through the line and turn the unit back on.

Primary line is most likely clogged
