Water Log: How Dry I Am: A/C Condensate Line

So after coming to the conclusion that the condensate line was clogged, I took a lesson from "There I Fixed It" and took matters into my own hands:

P-Trap before:

I should have taken this picture before I cut the pipe (and without the Walmart bag used to funnel condensate into a bucket) but cutting it gave me the access I needed to flush out the condensate line - and proved by leaking all over the place when I cut it that the drain line was plugged.  I couldn't get access from the far end - it's bolted to the floor with the tube going down the drain as part of another "fix" where the condensate was draining on the floor instead of down the drain.   I couldn't get access from the top end / inside, as one of the screws to open the access panel is inaccessible - hidden behind the ventilation pipe for the furnace.


P-Trap after:
The problem in just gluing the old cut line together was that I was going to have to likely blow out the line again.  So we now have a condensate drain line with features - not as fancy as the solution I found on the web, but close to it, considering that the solution found on the web was not available at the local big box store.  Note the options:
1)An access port, currently with a cap on it, but with a separate attachment (out in the garage) so that I can hook up a hose and clear out the line.
2)A valve at the top, so that I can block the clearing out of the line from backing up into the A/C coils and flooding.
3)The p-trap is lower.  If you want to know whether the P-Trap is blocked (I wish someone would make some clear PVC pipe...) open the access port.  If water runs out, the P-Trap is blocked and water is backing up.  If water doesn't run out, but is found on the floor, then I've wasted a perfectly good Saturday playing with the plumbing.

Good news is, when the A/C is running, you can hear the sound of water running down the drain.  So, it looks like I've "done good".

And here's the complement to the June 8th post showing the after of draining into the drain and not on the floor:
I had to bend the drain pan a bit to get access to the drain (the new water heater was bigger than the old.  The water heater drains into the condensate line, but just a little bit off the floor so that the condensate line drains into the drain.  I used a T rather than an elbow 1)because I had a T, and 2)so that if I ever want to drain the water heater, I can run the output right into the drain.

Thank goodness I married MacGuyver. Love you, honey. I do NOT do hot very well. (Word verification was "trashi" by the way.)

Trashy may describe the source of some of the parts I used. Audrey's PVC dog wash from middle school was cannibalized.

The house is PLENTY cool; and the nights are cool too, so I've turned off A/C at times during the day & night.
