    Attaching PVC pipe to concrete

    My air conditiong unit (in the basement) has a pump which pumps the condensation up over the AC unit into a drain pipe in the ceiling of the basement, the pump has failed me several times resulting in water on the basement floor. I plan to eliminate the pump & run 3/4" Pvc pipe to my sump pump & have it drain by gravity. Cutting, glueing and running the pipe looks pretty straightforward, is it? What is the best way to attach the PVC pipe to the concrete walls in the basement ?
    Thanks

    Dennis,

    As far as brackets, I would use the metal brackets used for electrical conduit. They come with screw holes on either one side or both sides. I'm sure they sell pvc/plastic brackets. The plastic ones would probably crack if you get your fastener too tight. The metal ones might deform a bit, but would still work.

    As to mounting them, you could go with lead anchors. They would work well for this. Another option is Tap-con masonary screws. They are blue in color and can be found with the other fasteners at Home Depot and probably most other hardware stores.

    The main thing in doing this, would be to make sure that your PVC is pitched toward the sump. This is one time where the goal is not to be level.

    Just my 2 cents, hope it helps.

    Sean nailed it. Will just add one thing. Put a T in the line and cap it off but leave the cap unglued so you can pour some bleach down the line to kill any algae. Otherwise it can stop up the line and still back up.

    Jeff, in all due respect I have some concerns about your post. Now I am not the most earth-friendly woodworker/ homeowner out there, but since this is going into a sump pump, I have concerns with where this bleach is ultimately heading. If it heads into a city sewer or rural leach field I have no issues with it and will give you an apology, but here in Maine a lot of sump pumps just dump the excess water downhill from the home. You might not want to be pumping bleach there however. Just something to think about.

    As for attaching the PVC to the concrete walls, plumbers tape would also work and give you plenty of options. Its this soft metal that has a row of holes in it and comes spooled up. Its kind of pricey but is designed to be bent around pipes and ducting, and yet can be nailed anywhere thanks to the holes in it.
    I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"

    dennis,
    any fasteners you use will require a hammerdrill to install, if you don`t own one i`d suggest going to your local rental yard and renting one for a couple of hours. they should have fasteners and the correct bit to make the job easy.
    if you opt to purchase a hammerdrill look at the sds type for medium to light duty, 2-300 bucks.

    A channel Strut. This is what we used in my basement to attach pvc drain pipe from my water softener to the sump pump pit. Very rugged. YOu can probably go to an HVAC co and buy a few inches/ft. google B-Line, they manufacturer all kinds of fasteners. www.b-line.com I think

    Yup, but also add a vent pipe. Had my furnace replaced last December and they did all of this: made sure it sloped to the floor drain, hooked up both the A/C drip and the furnace drip (higher efficiency furnaces also have condensate dripping from the exhaust), and added an air/vent at the starting end, to make sure that things flow well - and it also serves as a cleanout.

    Travis, when I was a kid we lived on 1 acre with a well and ever now and then (no more than once a year) my dad would dump a whole bottle of bleach into the well to shock it. This was as instructed by some gov't office that he had consulted with on some aspect of the well. (Sorry, I was a kid, I don't remember more details than that) For a few days, we were getting the same chlorine taste as the city water.

    Just pointing out that a tiny amount of bleach to clean out a line is likely no big deal, all things considered.

    I'll add that a quart of bleach diluted into a regular sized sump crock is going to be fairly dilute. Plus it isn't like you are going to do it every day.

    You are probably right...they do recommend running bleach through your coffee maker now and then to clean it out...now that I think about it. I was probably out of line...my apologies.

    Can I just use a regular electric drill with a bit made for concrete to drill the holes for the tap -cons? (I see that a bit comes with the box of 100 tap-cons)
    Thanks
