Behind toilet vent fan (works 100%)

pebble | Posted in General Discussion on December 28, 2006 08:36am

I posted earlier here… http://forums.taunton.com/tp-breaktime/messages?msg=78321.1

… to see if anyone else had installed a vent fan behind a toilet to well… keep the disagreeable odors at bay. The last few days I went ahead and with about $65 worth of parts from Home Depot, installed it. I used a 4″ inline vent fan (about $26) that I found in the duct department. I simply cut a hole behind the tank, ran the duct, cut a hole through my block wall (which gave me the perfect excuse to buy a Bulldog SDS rotary hammer), stuck a dryer vent with the flapper to keep air from coming back in, and for now wired the fan to a remote controlled plug thingie I picked up for cheap at a dollar store closing.

I put everything back together tonight I tried it out. For the first time, I didn’t smell anything at all. I am pleased as punch 🙂 My guests and the occasional girlfriend will be too I am sure.

Here are some pics.

    You didn't have a toilet installed.

    Of COURSE all the stink went away once you installed the toilet !!!

    Yeesh...

    You should get the rest of that pink board covered with rock.

      I am doing that over the next few days, as well as rocking the Icynene. Thanks for the concern :)Once I do that I will seal the duct joints... I need to take everything back apart so I can put the drywall up. I also drilled a hole for the water supply to be relocated in a better position behind the toilet. I will need to do some plumbing work as well. All in all just one little project at a time to tackle.I am still amazed how well the fan works. It is 80 CFM and despite that I can barely feel it when on the throne. Yet I can't smell a single thing. It is a big change.Handyman, painter, wood floor refinisher, property maintenance in Tulsa, OK

        as my ole granddaddy use to say--and I quote

        "I wonder why people crap in their house where

        they eat,and then go outside and eat where they

        should go to crap"? of course this was before they

        had indoor plumbing and he had a dislike for picnics.

        Glad you unlocked the" mysteries of the fartfan". :)

    You should have stuffed some newspaper in the flange before drilling to keep trash out of the drain.  Well, never mind the trash, I would have dropped the car keys down the hole.

    Did you measure where to put the elbow, or just get lucky?

    Man, you need to change that potty seat!

      I measured the elbow location first. I didn't want to cut into that stud. If I can find matching seat I would! As it was that was the closest thing they had in navy blue. Hmm I need to do an internet search for one now.Yah I got lucky not dropping anything in there. As it was it only took 15 minutes or so to make that hole so I didn't leave it open for very long. Hardly any debris went in there.Handyman, painter, wood floor refinisher, property maintenance in Tulsa, OK

        I was talking about the pvc pipe, not the stud.

          Oh the PVC drain pipe. Nah I wasn't worried about it. The elbow fit nicely inside the stud bay and the PVC was outside of it. I had to trim some of the Icynene to allow the non-flammable flex duct to slip over the the end of the elbow. You guys should try this sometime! I was at Lowes and saw a motion activated switch for $16. If I put that behind the toilet a little to the side it can automatically come on when someone sits on it :)Thanks MCDESIGN and mike585 for the compliments. I have tried three times so far and I could not tell one bit I was doing anything. I tried and tried to smell something... nothing.Southbay, the fan is just an 80 CFM inline booster fan marketed for boosting airflow to rooms that are not warm or cool enough. The short run is perfectly suited for it. Otherwise I would have gone with a fan from P-Tech or something like that which run about $80 and are totally silent. This fan is a little noisy.Handyman, painter, wood floor refinisher, property maintenance in Tulsa, OK

            Maybe now you can say "Handyman, painter, wood floor refinisher, property maintenance, and %#!& don't stink in Tulsa, OK

      "Man, you need to change that potty seat!"Is that the potty seat or is the breeze from that fan causing waves on the water surface? :)BruceT

    Nice work.

    What meal did you have before you tested it. How do you know you pushed it to its limit?

    That's really a sweet install, and something I've always wanted to experiment with.

    Now you get to test it, measure it, really push it.  Challenge the "occasional girlfriend".

    What a lot of fun

    I see you used the non-flammable metal duct. Good choice when dealing with flammable toxic vapors! Is the fan intrinsically safe? :)

      Hey, that's a whole new angle!  Guess you'd need a TEFC motor.
