Cut the red wire from the furnace to thermostat and connect the yellow wires to the cut ends of the red wire.
Pump condensate into attic.
This way if the condensate pump fails the safety switch yellow wires it will stop the furnace ac and no more water from condensate will be generated.
The white piping is a gravity drain that moves condensate from the attic air conditioner air handler down into the condensate pump reservoir.
Over time it can become trapped in your condensate drain line causing blockage.
Click on the special pump link in the article above or the innovative pump unclogs ac condensation drain lines article link in the further information section above then click on the mighty pump link in the article to go to the website of the company that makes it where you can purchase the pump online.
Yes this is why i have such distain for 90 furnaces in an attic.
For instance a clog in your drain line can cause condensation from your heat pump unit to back up and spill out over the drain pan leading to mold in your insulation and drywall rotting attic floor joists and ceiling leaks in the rooms below your attic all things you don t want for your home trust us.
I ve also seen heat tape warp pvc pipe sort of spiral like a unicorn.
90 furnaces still have an issue even if the drain don t freeze long periods of non use can make condensate problems within the heat exchanger.
Condensate switches imc 307 2 3 states that all hvac equipment that produces condensate must have either a secondary drain line or a condensate overflow switch a secondary drain pan with a secondary drain line or condensate switch or some combination of these installations should be used to prevent overflow if the primary drain line blocks.
So the first sign the condensate pump took a crap is a wet spot on the ceiling.
This pump has a secondary float switch to shut the system down if the pump fails.
You can heat tape but your chances still exist for problems.
Hopefully that will stop wet spots in case of failure.
Build up of this debris can be carried off as condensate drains from the coil.
So my roof isn t leaking.
We can t see much of the condensate reservoir because the installer placed this pump down into the attic floor so that she could drain condensate into it by gravity.
Except no one dwells in the attic as much as a basement.
If heating or ac are a must then connect the yellow wires to an alarm.
