This pump has a secondary float switch to shut the system down if the pump fails.
Pump condensate into attic.
If heating or ac are a must then connect the yellow wires to an alarm.
Hopefully that will stop wet spots in case of failure.
Cut the red wire from the furnace to thermostat and connect the yellow wires to the cut ends of the red wire.
So my roof isn t leaking.
The white piping is a gravity drain that moves condensate from the attic air conditioner air handler down into the condensate pump reservoir.
Heating your home produces warm air that rises and if it seeps into the attic space the frost will melt and appear as condensation.
If you can t identify any exterior damage to your roof or track down a leak the source of your water damage is likely water condensation.
So the first sign the condensate pump took a crap is a wet spot on the ceiling.
I ve also seen heat tape warp pvc pipe sort of spiral like a unicorn.
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.
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.
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.
Yes this is why i have such distain for 90 furnaces in an attic.
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.
Build up of this debris can be carried off as condensate drains from the coil.
You can heat tape but your chances still exist for problems.
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.
Except no one dwells in the attic as much as a basement.
