In any case, since you don’t have access to the exterior end of the line, I’d recommend blowing out the A/C drain line from inside. Of course, this is assuming your home has curtain drains, and the A/C line isn’t just draining directly into the soil below the basement. A curtain drain is a network of perforated PVC pipe that carries groundwater away from the foundation. Hey Kevin, If the A/C line runs under your basement floor, then it’s probably connected to the curtain drain that runs around the exterior perimeter of the foundation. should not have cost them over $15.00 Bulk (PVC parts are Cheap.) the moral is always ask even if you do know the people, I have known these people over 19 years.Īnother thing is 4 straps is not enough when the pan gets stopped up, I had him put two addicional straps on it (One on each side in the middle) could not find it in the book is that the book is the book shows P trap & all & he said that he had not installed a P trap & did not know what to charge.įolks The switch assy is PVC T & a switch setting in the top which shuts the unit down when the line gets stopped up the whole assy.

He sent a man out the next day & he put two in one house & one in another & the man could not find it in his book so he said that he would have the office call me with the bill when he got back in on monday, well they called me about two weeks later & ask for a cordite card number & then I got the invoice’s I had paid $140.00 each for the float valve & switch’s a total of $578.00. I blew the lines out with air & called the A/C owner & he said that they had had problems with the pans lately, & said that they have float valve that they had been putting on the units & he had them in stock. & in one the pan below the upstairs unit bent & leaked water in the ceiling. Wouldn’t the PVC line that runs to the master bath area be the primary drain line? Doesn’t seem like they run together to me? So now I’m confused about what the tech said and whether I blew $85 for nothing. The outside pipe seems to have stopped flowing. But now, there is a very slow drip of water into the pan coming from where the PVC pipe that runs to the bath connects to the handler. Also I can feel air blowing through the pipe when the cap is off and the unit running. The water in it got air bubbles in it, then went down and you can see a slow trickle running in the pipe now. I removed the cap on the one PVC line that ran to the bath and poured about a cup of bleach (in 3 portions) in the opening. This is what has been running with water.

A second PVC pipe comes out of the unit, joins up with a PVC pipe coming out of the drain pain and then runs outside under the eave of the house. I removed it and it had water up inside the tube and did not appear to be draining.

There is one white PVC pipe coming out the bottom that goes over to my master bath area. This is a Trane handler unit in the attic. This seemed strange to me and I went and looked myself. He noted on the sheet that the emergency and primary drain ran together and then outside the house. A tech came out and said he blew out “both lines” and they were fine. I just noticed the same problem as Richard (I’m in Fort Worth, TX).
