Adding a condensation switch

I have owned an upstairs condo in central Florida since 2005. Over there years I have had a few times in which the condensation line has leaked and caused damage to the lower unit. Stopped up lines, found the PVC had not been glued at 2 joints also. The line was vacuumed just over 2 months ago and clogged again last week. I have used bleach to try and keep it clear and this time used vinegar. The A/C unit is in the center of the condo with vaulted ceilings and the drain line runs thru the floor. The drain line comes out of the bottom of the pan with a 90 degree elbow, does about 8" then another elbow and goes down into floor. I have been told I can not add a float switch. Is this true? can't I put one into the 8" pipe? If that's too low can't I T up and add it at the pan level? I have thought of adding a pump but not sure how to run the new line. If I can install a switch what kind, where in the line, and how? Any ideas would be appreciated.

Adding a condensation switch

Looks like you need to clean the coil.

Adding a condensation switch

Install an E Z trap with switch.


Also, that coil needs cleaned, and is probably why your drain line is clogging up so fast.

Yes I saw that it needed cleaning, but I did not realize that would stop it up faster. Thanks for letting me know
I had also saw the Safe-t-switch which is similar and found the Diversitech SOS-1 which looks the easiest to install.
Anyone have any experience with it?

The SOS-1 is nice, but I really don't trust it compared to a float switch on a trap like the one that BT suggested.
