Dude...this is absolute genius... I was shopping for a smoke machine, but I dont want to pay $700.00... You ROCK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Great Video! Suggestions 1) Try using your shop vac without smoke first to see if your sink vents/toilet gurgle (vent) 2) A smaller shop vac will have less blower pressure in your vent system 3) Buy a "2 1/2" blast gate" from HD or amazon for $10 and use it on the shop vac outlet to reduce blower pressure to your vent stack 4) Install the Blast Gate to the Shop Vac Outlet, use adapters /carboard/Duct Tape as needed 5) Adjust the blast gate until the fixtures stop gurgling
@@redwood1957 YES. You probably dont need to cap off vents on roof. If for some reason you can’t find the smoke leak in the house and you think you need to cap off roof vents, DONT BLOCK THEM OFF COMPLETELY! You dont want EXCESS pressure building up. All you need is to make a cap with tin foil to go over the vent enough to keep smoke inside the pipe. This way it will force a little more pressure out the leak you are looking for. You DONT want too much pressure…only enough to come out the suspected leak.
Hey thanks so much for this video. I used a spare wet dry vac and was able to test my sewer pipes for leaks. Works so well and didn't cost anything except the cost of the candles
To everyone worried about blowing out the traps, pick up a little $15 router speed control from Harbor Freight or Amazon and you'll have full control of that power! This build is AWESOME!
Put a tee with a valve in front of elbow to moderate air pressure. Leave roof vents open until they blow smoke then tape them making sure you open valve in front of shop vac elbow so you dont blow toilets n traps.
Can you please explain a little bit more. As far as my understanding that you instructed you to put A tee on that 90 . and on that Tee on the other side equipped with an open and close valve to control air pressure? Why not just install a Tee and plug one into the vent and the other side of the tee is still blowing smoke and pressure out . The reason I'm asking is because I'm going to do the same route as the video above. Thank you for ur sharing.
IT doesn't. I tried, nothing came past it. If it does, your roof vents are clogged. You could also restrict shopvac intake a little to prevent too much air.
If your vents are working as they should it will not blow past the traps. I played with it and I could see the water rise a tiny bit but air would not get past toilets traps at all. If you do have it happen just block the shop vacs intake port with something. You could even buy one of the shopvac plugs and drill holes in it.

Can you do a test with out blocking roof vents as they are hard to get to. Mean roof pitch. Thanks

You have no idea how helpful this is. ❤
My idea confirmed, thanks!
Where did you purchase candle

Would it blow out the traps because of high pressure?
I have seen less blow out the traps wouldn't surprise me if they had to go back
Yes. It even blows all the water out of your toilets

can I use my 7 gallon ridgid "Plastic tank" shop vac instead of the Stainless.. and will use a coffee can inside?
Sweet! So simple and effective
I been told those candles smoke will damadge fabric and art wallpaper... Is this an issue?
I doubt it for this short exposure.
Sweet, my first thought I didn't copy comments, lol, thanks for sharing....
Is they too much pressure could it blow past the traps
If your vents are working as they should it will not blow past the traps. I played with it and I could see the water rise a tiny bit but air would not get past toilets traps at all.

Do you plug off the city side of the clean out when testing thanks
which size fernco is that ? great video
Nice unit. Where do you get the candles
This is amazing
That’s bad ass bro
genus
Ingenious
Copied my idea
Tried this. All it does is blow all of the water out of the toilets & fill the house with smoke
Like others said, put a t-valve in line on the shopvac inlet and control how much air is pumped out (which goes into your sewer)
Guess you have leaks...😮
Or, you know, buy a real one. But yours is good too.
600 bucks+ for a smoke machine is insane. This will cost you a little over 100. And you can use it as an actual shopvac as well. Superhandy
