    Water under air handler
    Ok here, I here's the problem I have water coming from under the air handler'
    I have already taken the drip pan out and cleaned it I did not see any holes so I put it back I noticed that the insulation in the back,inside the air handler is wet so it would appear the water was coming from the pellum but I cut a hole in the back of the pellum and did not feel any wetness. The pipe for drain line was also replaced any ideas would be great.

    If it's a fan coil (blower on top of unit evaporator coil on bottom) do you have a condensate trap and tee after the trap on the drain line.

    There is no ptrap if that is what you mean there is a tee in the line though. But the line seems to be dry.

    If the coil sets below the blower you need to install a P trap with the tee after the trap. With out the trap the blower will suck air through the condensate drain keeping it from draining. With out a trap the pan will get full and the blower will start sucking the water out of the pan. Good luck.

    Thank you very much for the insight that worked. I was stumped with this one.
