    ABSOLUTELY POSITIVELY NOT!!!

    seriously dude. Your water heater is exhausting carbon monoxide and the flumes on water heaters and high efficiency furnaces are very sensitive to different back pressures. If you tap into that exhaust, (even if you tap in with a Y and not a T) your going to be pushing deadly gases back in to your living space.

    Surely you can find another vent. Does it vent into a chimney that you can run another line into?

    Yes agree do not use , Not advisable if you do use a y your vent must be under , hw heater top ,but also you will def create moisture ,I meat alot of moisture where a constant flow will flow in to the exhaust line, So not advisable

    wait a minute, what? Is there ACTUALLY some consensus on something on RUI? Surely there will be some guy that will chime in and say "no problem dude, I do that all the time".

    Ok this is the deal its the 5" triple wall chimney pipe the furnace comes in the bottom and the hot water heater comes in the side...
    What i wanted to do was put another pipe in the side of the chimney pipe like the hot water tank has...
    This is why I ask because i know it has carbon monoxide but didn't know if my exhaust fan would push it out and not let it back in...
    My last post was not very detailed because i was on my cell phone lol didn't have much time to type it next time i'm just going to wait tell i get home lol...

    Thanks for the info guys keep it coming its my first grow i want it to be right and safe..
    also in the laundry room i have the vent for the drier but that has lots of lent not digging that..

    No No No 5'' to small it will pump back through hot water heater , the chimny is sizes just for those 2 , sound like your furnace is already fan induced, (high eff furnace 90+ )

    Just hang a small carbon filter...A GOOD one like a mountain air and a cheap 6" inline fan from the ceiling. Run it 24/7 in the last month of flower.

    Done and done

    Yeah I was looking into the idea of carbon filter like this http://www.rollitup.org/do-yourself/58871-2-minute-cheap-easy-carbon.html because it just so happens i have that air filter just sitting around collecting dust and run ozone generator like this http://www.rollitup.org/grow-room-design-setup/86320-my-highest-reccomendation-inexpensive-unit.html later on down the road if it get real stinky ;-).

    All though I like this idea too and it kind of looks like the filters you mentioned http://www.rollitup.org/indoor-growing/7074-easy-build-diy-carbon-filter.html

    Thanks for the info on the heater exhaust.

    no problem. I can't remember how many watts your running, but in my own little arrogant way, I always equate those little DIY carbon filters as only being usefull for little kids growing weed under their bed or in a PC case or some other completely ridiculous thing. It's strain dependent of course but when you start cutting and drying any decent quantity of weed it stinks to high heaven.

    CFs also wear out as they absorb particles (in addition to a bunch of other factors), the amount of carbon in those DIY things is laughable. The CF in my small room has about 20 lbs of carbon in it. The one I just bought for my project (10k) has 70lbs of carbon in it. Yes, 70 pounds... That is ALLOT of carbon.

    I'm sure you will figure it out but in the world of growing their is ALOT to be said for just spending the money and doing it right the first time instead of dicking around and trying to figure out some way to "make it work".

    cheers

    that carbon filter in the link is a fucking joke dude.

    That thing has what...6 ounces of carbon it it... maybe>? That thing is suitable for something like 1 small plant in a box or something.

    It's not just the issue of fumes if you tap into the exhaust line. You will be cutting a hi temp duct that will release an unimaginable amount of heat, along with fumes, back into your home. Never cut any ducting, exhaust or insulation that is more than 1 layer thick. They are those sizes for reasons. This is one rule I live by as a metal roofer and I do not have leaks, ever!
