Just watched great vid. I’ve found a concentric condensate fitting designed for just before/after the fan connection, it needs to be positioned in the vertical, but wrapping the pipe in rock wool will help to prevent condensate within the duct (some people find it drips back out through the fan)

Thanks. Yes I'm in a dry climate but I can imagine that could be a bigger problem in colder or humid environments. This is true whether you use metal or plastic duct. I usually leave my fan running at least 20 minutes after showering to allow drier air to remove as much moisture as possible from the duct before it stops

That's a smart idea!

Less dust sticking to pipe. Great job.

Very cool... but I wonder how hard it would be to replace with a different fan down the road since everything is rigid.

Recently fitted an inline extractor fan in our loft. I raised the height of the fan on a plinth so that everything from the fan exhaust is downhill.

good move. Indeed I believe most building codes call for a 2% downward slope.

good idea

Good install Indra, however I don’t think you should have put the mounting flange on the inside of the wall, the outside flapper/finish plate clips on to that piece and you have the thickness of the wall in between them. I’ve always just drilled a 4” hole and mounted the flange to the outside of the wall and clipped on the cover. An insulated sleeve will help with condensation, it’s just slipped over the pipe.

Thanks for the comment. You're right - I should probably have mentioned this in the blah blah. In most installations I agree that what you describe is how it should be installed. However, my wall was already existing. I didn't want to damage or have to re-do the exterior finish and the stucco is only an inch or so thick so I was able to put the flange inside and there was enough penetration that I could still clip the cover on from the outside. This meant that I didn't then have to figure out how to cover up the flange on the outside surface of the stucco. I was concerned about that and until I checked the thickness of the stucco I considered changing my vent and the install method. In summary I ended up with an 'un-conventional' installation of that particular style of vent. I've added a note in the Description about this

Awesome job. I am just realizing that I will want to use rigid PVC. That exhaust outlet looks nice. Where did you get that? I read recently that it makes sense to insulate the fan box too. That cold metal box can also condense your humid air rapidly. I plan to do that too.

Thanks ! The vent was from Lowes. There's a link in the description.

You actually WANT the water to sit in the "ribs" of the flexible duct. That way, it doesn't run back into the blower/inside the bathroom. The ribs and a small horizontal run give it somewhere to settle and evaporate.

Thanks for the comment. Yes that could be a factor which is why I sloped it very slightly downward towards the vent so it wouldn't run back towards the fan. Also the pipe I used is not entirely smooth inside

will the steam , turn back into water when it enters the rigid pvc pipe and run back down and shorten the fan ?

Hi. Good question. Shouldn't do because I made sure there is a slight slope down away from the fan on the long section. Also the inside surface of the pipe I used is slightly ribbed. Plus I'm in California so we don't often have long periods of really cold or damp weather

Hello, I recently removed the flex pipe from my bathroom fan and intend to install pvc also. I don't want to glue the pvc to the fan, so I was thinking of getting a flexible coupling. It appears that you secured your piping to the fan using metallic tape only, am I correct or did you also glue it?

@@dadlifediydoityourselflike2293 Nice install! Just a couple questions/concerns but may not apply to you. I did this kind of install as well 5+ years ago but a longer run to my exterior wall. Some of the things I ran into that I've had to modify since then may not apply to you based upon your climate. I live in New England USA where during winter, our unconditioned attic gets well below freezing. I also used the metal foil tape for my connections initially. My challenge comes from the condensation that drips out of the vent flap will freeze once the fan is shut off because there is a small quantity of water that remains under the flap (I have the same PVC flap you have shown). As a result, that flap won't open the next time the fan is used if its still cold out and believe it or not, the fan in my case was powerful enough to pop one of my connections that were taped. I didn't know this until I started seeing water stains on my ceilings below. If you may have these same cold temps, I suggest converting as the other poster asked to the flexible couplers. I've had no issue since then. Likewise as someone else has posted, if you do have really cold winters, do insulate around the pipe. It will prevent so much condensation inside that can cause that flap to freeze shut. Finally, I couldn't really tell by the video what the final connection is to your flapper, but just be careful about that connection as goes through your exterior wall as this connection is not water tight and any condensation that collects or passes through this zone will find a way through the connection and into your wall. Again, not sure if your connection is actually outside the wall or in the middle or worse, inside. I've been searching for a good way to remedy this online for some time which is why I found your vid. I think in the end, insulated pipe is the best solution but I haven't gotten around to it yet so I just need to make the move! Either way, much improved over the flex stuff!

@@vcookster3915 thanks for the constructive comments and for sharing your experience. I live in southern California so I'm not subject to the kind of temperatures you're seeing. Your comments are therefore appreciated for those who watch this vid and live in colder areas. In that case I would support the insulation and other comments you made. My exterior wall is stucco and doesn't have an internal wood or other surface inside it interestingly. My connection is inside the attic and for that reason I was careful to seal it with a silicone based sealer that bonded to the pipe and the vent flange. I also sealed around the opening that I cut into the stucco. Any drops etc will therefore have nowhere to go other than outside. Amazing that your flap stuck so hard that the pressure popped some joints in your pipe . Wow.

You spoke kind of fast, but did you say the pvc was insulated? If not, the pipe is going to sweat on the outside and drip onto the joists.

It's triple walled so I doubt it will sweat on the outside. I also live in a low humidity area. However I will check it during a cold spell to be sure. Also, as another commenter mentions, the duct can be wrapped with insulation if necessary, depending on the climate where it's installed.

Bath vent pipe have to be insulated. This would never pass code FYI

Since you're using a rigid duct, did you consider using an exterior wall mounted exhaust fan?

That could be an option but not commonly sold in my area and I'm not sure if it meets local codes. In fact I did consider using an inline fan as they can be quieter but in the end I went with what was cost effective and easily available which was the ceiling mounted unit

yes and it saves the possibility of damp condensing from the vent onto your outside wall

Your wiring is unsafe (fire and shock hazard) and not code compliant. The wiring connections need to be terminated in the junction box in the fan. The cable sheath needs to be continuous between junction boxes and secured by an approved cable clamp. Your installation would be an immediate fail if discovered in an inspection.
