MORE conduit than you will EVER NEED, is ABSOLUTELY TRUE!! I trained my guys by pointing to a bag of 50 fittings, and a roll of 1000 ft. and asked, "How many do we take in the field to the next county?" Idunno............ 2 fingers, TOO many and TOO much, that is how much we take from the warehouse when we leave. Or, or, you can drive back 27 miles to get 4 more fittings, out of a bag of 50 which no one is counting or caring about. In this case I NEVER would have put in 1 after all that digging, and etc. Put in 2. The next one may be used in a decade, and possibly not by you, but follow YOUR principle, you stated, "MORE conduit than you will EVER need!!"
When you force a sleeve under concrete like this you aren’t able to properly backfill, ground will settle and cause your concrete to crack and shift a ton over time. Also that void will fill up with water and freeze in the winter
unlikely with less than 18 inches, however sand will not settle, and expanding foams are used to raise concrete nowadays, so getting some upward pressure is not that difficult anymore.
I’ll be honest I’ve been doing electrical work for almost 4yrs. I’ve done similar tasks before. Never even occurred to me to use a pusher washer inside a conduit. I guarantee we would saw cut that concrete if my company was doing this project. Going to save this one in my back pocket!
That's what I did. Pound the pvc as far as itll go, use the water pressure to remove the dirt and keep pounding the PVC pipe till it pops through. Was a bit of a slow process as I was working through clay 🤮
Do this everyday and I know it sucks but you gotta wet saw that section up otherwise like the rest of these professionals are saying it will never be backfilled correctly thus caving/cracking will happen.
depends what you get in the pool but even bare bones skimmer, 2 to 1 suction and 1 to 2 return is 2 50mm pp and 1 40mm pp that don't bend, you use fittings to run it... so that "extra" conduit would only be suited to light cables...
Use a ground rod in the conduit and a water hose turned on low, it will push right through. Also cut a 2 inch by 4 inch hole in the concrete you can work a 90 up the wall out of that hole easily.
I don't know about that. Could a separate electrical feed from electrical source not be done. I knew a guy that did that. Of course, it required an additional meter. But he was rich and could afford it.
Wrong way to do it. You have a huge void under your slab now, it's going to crack. You gotta get the tool to drive the conduit with water pressure so the hole is only the size of the conduit.
And always leave a pull-line in the conduit for future pulls.
...and IF you use the existing pull line, pull in a new on also. You are not the only one or this is not the only thing that may use that conduit.
Always do pipe fill and wire de-rating calculations so you don’t overfill your pipe.

@@MarkH10 no way in hell he’s going to think to backfill that with polyurethane foam
@@Swof99 Exactly how weak is an 18 inch span with 2 inch depth?
The concrete will Crack where you used the pressure washer.
That's a problem for future self. At least that's what I say to myself
How you gonna back fill under the slab?
Foam.. Easy
We pump sand or bentonite.
Foam works too. Especially there which wont get much traffic being the HVAC compressors and elect. panels right there.

Then later you can figure out what to do with the big ass crack in the concrete from undermining it. SMH 🤦🏼♂️
Did you spray the pressure washer through the pvc pipe while you where pushing it under the slab?
That's what I did. Pound the pvc as far as itll go, use the water pressure to remove the dirt and keep pounding the PVC pipe till it pops through. Was a bit of a slow process as I was working through clay 🤮
Obviously not, look how huge of an area he excavated.
Are you concerned that after you undermined there that the Crete is missing material tm there and possible Crack after some time?
I thought the same thing!
Google Translate has no Phucking idea WTF you just typed.

We backfill under slabs with pumped sand or grout.

After what you did, that concrete pad is going to crack prematurely.
and why is his conduit a foot away from the house? it's going to look like shit
@@TheDarthJesus it's not. It's 4inch away. A simple offset pipe will look fine.
@@randybobandy9828 4 inches off the house sounds like a tripping hazard.
@@TheDarthJesus
Nobody is walking that close to the elec. panels and adjacent to HVAC compressor anyway.
@@benjurqunov It's still ugly as fuck for no reason

But now you have voids beneath your slab and will get cracks. Even if you pumped in sand, it will settle.

Yeah maybe 10 years ago when conduit was cheap.
Don’t forget the pull tape inside that conduit as well!
Please tell us you back filled the hole with concrete after removing soil with the pressure washer
Where's the gravel that's supposed to be under the concrete? That will 100% crack in the near future due to settling from your digging.
Tf is this guy talking about this is the first shit I think of when there's concrete being poured. A sleeve takes 15 minutes to install
Nice job
Utility workers would appreciate it. Run 5 pipes. Why?! Becuz future shit
Good job.
Do yourself a favor and don't get a pool.
Seems a little shallow there
That's what I thought. PVC needs to be deeper right?
@@Greeko_Poloz NEC 300.5 says 4in. Under concrete but 18in. Once it's not protected by concrete.
@@Greeko_Poloz concrete needs to be at 4in for this to be true. If not it'll have to be 18in all the way.
Run it to where? Just random spots?
The fuck, cut the concrete dig dirt, install conduit, back fill with dirt, compact dirt. Poor concrete
Nice!!
Tell this to the home builders !!
From what I see. You are rebuilding the house that you paid someone to build it for you. That’s how it is around here.
Ya just under mined the shit out of ur slab
Couldn’t you have went around the concrete and then bury it?
Someone’s going to grow weed at home
Lmao what? No.
That grave your digging is a little small, from experience I recommend it to be at least 7 feet deep and 4 feet wide! Hope this helps!
Not a good idea at all.
Should’ve grouted that tunnel to avoid future settlement.
8 inch depth... definetly not up to code
Do yourself a favor and don’t do what this guy does?
Did you fit a pump out point on the conduit?
I've never seen a "pump out" point in an electrical conduit, water doesn't get inside and if it does you did it wrong
@@Schmuly exactly, all I am alluding to is look at picture, open-ended pipe?? Food for thought🤔
Yeah yeah, it’s very easy👌🏻 lol 😂
Or you could just repour the slab, not the end of the world
For a moment there I thought he was digging his own grave
Doesn't PVC need to be deeper than that? I thought only rigid metal could be that depth.
Not when covered by concrete. But it needs to be 18" under once it leaves the concrete cover (check your own jurisdiction).
Now that you didnt backfill the tunnel...
Code for a buried pipe is 18”. Just do it right and cut the slab. Also if your going to do sub par work don’t tell anyone about it or post videos.
used a pressure washer, nice.
That moment when you try to give advice but end looking like a idiot
Run it
Bury it to proper depth next time
T 300.5 Nec 18 inches!
the duck is conduit ?
What not to do. 🤦🏽
I ran conduit on mine!!
Nice!
