another "dryer" vent thru concrete

[WasntMe]

for 3- 600w I would want at LEAST a 6" exhaust line ... especially with the length of the run and all the bends

not sure where you are located but like stated above (if in your area), look to rent at:
- Hilti or Dewalt supply stores
- Home Depot or similiar
- Look at Tool Rental in yellow pages
- Marina repair shops sometimes rent out tools too. (but masonry bits harder to find here)




Or you can get an Electrician to quote you to do the core drill for a hole "the size to fit a 6inch conduit for future use".




Good Luck

ok two 6in cuts is what i told him. after seeing the youtube links above he feels a little better about this adventure.

he is wondering if it would look weird to the trained eye having 2 6 in vents coming outside of his house. it is in the back, nobody goes back there he said but meter reader twice a year. i guess he should look for an external vent cover for the outside and paint his house color? is that what you would call it?

examples of the variety available... find a 6" on that matches the house style... paint it if necessary.

if you get a chance, take some pictures so others on here can learn from your experience

if you can't rent the 6"in bit ... you could buy it and give to your friend, along with a few beers, as a thank you for helping you out.

I use to core drill and hammer drill for a business that I had in the past. Core drilling is super easy, and faster than you would think. If you core drill it will be a perfect hole. If you do a bunch of little holes with a hammer drill it will look like shit, and take a lot longer. Core drill it, and save yourself the headaches. My dime - 8 pennies.

also, never use cheap plastic ducting:

Normalguy... mounting the exhaust outlet up high, is better for smell dispersion, if you have to worry about smell. For that hole in the floor idea, smell would be in everyones face at ground level.

Not knowing logistically where the home is located, makes me
want to mention the story one might have to tell neighbors about
why you're drilling holes in the side of your house, thru the brick.
Same one you might tell someone you hire.

I'd go with 8 or 10 inch fans/ducting but I see your position with 6 inch. In-line booster fans would help.

Are you using the core drill? I didn't know about those until this thread. If you can get one, that's definitely the way to go. OrganicOzarks is right, anything else will look rough.

Let us know how it goes. Don't do less than 6". Stepping up with ventilation is always good, stepping down is always bad.

 

[WasntMe]

So how did it go?
did you guys make the cut yet?

ok drilling a bunch of holes in a circle sounds doable. his friend is a cable guy and has to drill thru stuff for cable.

That's how I did it at my last spot, on a budget and w/o any real construction, destruction, or concrete experience. Although the size hole being punched was much larger than 6" and rectangular, pretty much the same thing.

I did it with a Ryobi hammer drill ($60), a few Bosch 1/4" or 3/8" bits, a small chisel, and a wider chisel w/ target guard. Not fun. All the proper tools and methods these guys mentioned will probably make it a lot easier, though.

ok he did it. got a few pics till battery went dead.

he got a hammer drill with a 6in core bit. that bitch was heavy. i drilled he held the bit end up with gloves to get it started.





started with the pilot bit, once we got a good grove took it out. five min of drilling we got as deep as core would let us.



took off core bit and put chisel bit on. that was fun. chisseled out the bit that was in there. that is the last pic before dead bat.





drilled a little more and broke thru. after taking into consideration everything else (plumbing, wires, cabinet etc) we hit a stud! that was a bitch!! drilled holes and chiseled it out.

taking stud into consideration second holes went perfect. we pushed the depth of bit to the limit and got thru without having to chisel.

inside house he drilled thru cabinet, drywall with a 6in hole saw for wood to match up holes to outside. then drilled thru bottom of cabinet and floor into basement.



everything, although a pain in the ass work perfect. the brick work was the easiest. had to take plumbing and disposal out mixed in with tight quarters made the rest the hard part. thanks for all the help guys. sorry to take so long to get back.

hope someone else can use some info here for good use. cost 40 buck to rent bit and drill for 4 hrs. pretty easy with the right tools

good job with your first core drilling experience ..... yeah having the correct tools always makes a job easier.

glad we were able to steer you in the right direction.

suggestion .... since you are already in what appears to be the cabinet below your sink ... are you adding an RO filter?

 

[normlguy]

he was looking into one of those $120 jobbers to hook up right before his water heater. he said it would be worth it to not haul wata
