07 May How To Replace Flex Tube Seal Bathroom Exhaust Vent
Damaged flex tubes are a common problem, and they result in poor ventilation throughout the building envelope. Eric takes a look at one damaged flex tube linking to the bathroom exhaust vent and gives the insight on how to best solve the issue.
We’ve discovered a portion of flex tube up here in the attic that’s been crashed at one time in its existence — don’t know if that happened when it was insulated or when it was built — but this is preventing evacuation of moist air from that fan and preventing it from getting out of the building like it wants to.
So, what we need to do is we need to repair this flex tube. We’ve got some flex tube with us. We’re prepared so we’re simply going to take this section out and splice it back together.
We’ve shown you earlier that in our inspection process we found some compromised flex tub. This has obviously been crushed. It was terminated right here at this exhaust fan from this bathroom so while we’re here we’re also going to air seal this bathroom fan to the home envelope and install a new piece of flex tube. This comes in 25 or 50 foot lengths from any big box store and it makes for easier repairs when you find stuff like this in an attic.
