Drain Tube for central A/C Condensation Pump?

Question

I need to extend the drain tube outside for my central A/C unit. The area where it is draining is not absoring the water and the unit has quite a bit of water around it. I purchased 1/2 x 3/8 tubing. How should I run the extension tubing so that the water drains properly? Should I keep the tube flat, should I arc the tube up and then down, or does it not matter?

Answer 1

The condo pump pushes the water as it pumps. So it does not matter what you do just as long the line is not blocked or kinked. Make sure there is a check valve at the pump.
Good Luck

Answer 2

I'd arc it down, then up, so there's a water trap like there is in the drains for sinks (keeps bugs and mold out and stuff). The rest can stay flat or have a slight downward angle.

Answer 3

You need to extend the line with the same size PVC that's already installed. The 3/4" is sized for proper flow. Also you should remove the U trap and place it at the end of the run.

Answer 4

It's a drain. Make sure the hose goes down at all points. No hills or kinks.

Answer 5

Flat...or almost flat. It should have a slight downard slope from the point where you attach to the old line and the outlet of the new line.

Answer 6

listen to audioworm...he knows what he is talking about...the other answers came from people, possibly in hvac, but have poor training or just don't care anymore about the work they install. if you don't have the time to do it right the first time when are you going to find the time to do it a second time. good luck

Answer 7

It shouldn't matter as long as it isn't kinked and your pump can push it.
