We discuss refrigerant flooding and six common causes of liquid refrigerant slugging the compressor.
Insulation radon pipe condensation.
Insulation the easiest solution for condensation on pipes is pipe insulation which prevents moist air from reaching the cooler surface.
Most plumbers recommend plastic foam pipe wrap over fiberglass pipe wrap because the fiberglass is not waterproof and actually absorbs water.
The less pipe you have exposed to the moisture the less total condensation you will have.
Pipes that run above suspended ceilings for example will often not collect condensation because the area is drier than the basement itself.
Fire barriers must be used where pipe penetrates a firewall.
We can prevent condensation from occurring by insulating the pipe with enough insulation to keep the air around the pipe from dropping below the dew point.
This usually takes place in the garage attic and outside.
The amount of condensation is proportional to the amount of exposed pipe.
This can also happen inside your home.
A proper slope must be maintained for condensate drain back.
Removable reusable insulation blankets like thermaxx cold insulation jackets are designed to fit snugly and keep the ambient air temperature and humidity from affecting your pipe.
If using a porous insulation material a vapor retarder is absolutely necessary to prevent the water vapor from passing through the insulation and condensing.
Most professional installers in cold weather areas try to avoid condensation problems by routing the pipe up through a closet or finished garage and to a fan in the attic that blows the radon out above the roof.
Frustrated not sure what to do and drywallers are scheduled to start tomorrow afternoon.
Air conditioner heat pump refrigerant pipe condensation or sweating can occur either because insulation is missing from the suction line or because of an equipment malfunction like liquid refrigerant slugging at the compressor motor.
Use schedule 20 or preferably sch 40 dwv for strength.
This is new construction.
How much insulation does it take to prevent condensation.
When high humidity is present you will get condensation on the outside of the pvc pipes.
Thought we had fixed the problem but again today i see water drops on outside of radon pipe.
Be ready for a big dusty mess if you have to route your pipe indoors.
3 pipe is the minimum if your not sure use 4 keep the vent supported every 8 vertically 6 horizontally.
On all radon gas mitigation systems condensation will form on and in the pvc pipes.
We have a 4 radon pipe that goes from the basement straight up to roof vent passing through 1st floor 2nd floor and attic.
However if the insulation is porous the water vapor can still find its way through the insulation and will condense on the cold surface of the pipe regardless of the insulation thickness.
