Quieting a noisy direct vent water heater quickly and cheaply. 

i would love a follow up video to this where he pulls it out and takes a look at what it looks like today. there is a lot of moisture that comes through that vent. my guess is that the insulation collets a lot of it and creates a perfect spot for mold.

Thanks for the great idea ! Now if there were only some video and audio recording of the noise AFTER the modifications. Since you can easily remove the muffler portion, get a sound level meter, "C" weighting, fast response, and measure both inside and outside the home, and post the data here !! Thanks again for the great idea !!!!

Keep your day job

Why didn’t you just replace the 3 inch and install 2 inch from the heater to the outside?

Amazing video!! My sound issue is an actually the vibration of PVC pipe with the joists. Anyway to reduce the vibrations from the pvc into the joists?

A glass pack muffler for your water heater!

Question, how would you install an air trap in one of these hot water heaters so that I don't get a draft back into the house? The exhaust on my tank is 2 inches, would you recommend that I use a 1 inch pipe? Maybe I am overly thinking this, but if there is any condensation in the exhaust couldn't it potentially create mold on the insulation? Thanks

I hear noisy ones all over my neighborhood .. How about someone make a muffler to add onto the end.

I do have a question. Hi. What model of Bradford Whitewater heater is this? I’m just very curious. I used to have one and I like the sound can you please tell me

My problem involves the resonant noise is heard INSIDE the house. My exhaust pipe is 2" and the horizontal run is about 12 feet to the vertical that connects to the W.H. fan.

Why wouldn't you just swap the 3 inch pipe for a 2 inch pipe ?

If someone has a water heater like this, please tell me the model, and what year these are. Thank you.

Done listen to him

What is the temperature of the exhaust?

A quick question : how do you adjust the temperature on this same water heater ?

And wrap those pipes!

Iiiim not so sure that's a good idea.... my boiler vents that way and I could see that A. getting moldy inside a cold pipe and B. blocking airflow, putting both strain on the fan and maybe pushing CO back into the basement

just a heads up, if you're in Canada you MUST use ULC636 approved Gas Vent Pipe to do this. ABS DWV and Schedule 40 PVC are not legal for use in flue gas venting applications. For those in the US, the use of UL1738 approved Gas Vent Pipe is highly encouraged, and is required by law in some states already. As a general rule of thumb, ABS DWV and Schedule 40 PVC pipe is not rated for continuous use under the temperature of the flue gasses that are passing through them. Its also worth noting that the fittings some of these pipe systems use are only glued in place, not chemically welded with a solvent. The glue used for connecting ABS fittings to ABS DWV pipe in particular has been known to crack over time when used for flue gas vent applications. This is the exact reason more than a decade ago it was made mandatory in Canada to use ULC636 gas vent pipe.

I just posted an update so you can hear the difference before and after: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-a8dtlGKeOL4.html

Damn this isn’t safe bro

Won't have to run so much
