How To Install A Sump Pump Pit

hi I'm Shannon from host improvements

comm and today I want to show you how to

install a sump pit in your basement so

maybe you've got a bit of a high water

table or having a problem with moisture

in your basement and you've decided that

you're going to put a sump pit because

you don't have one basically you know

that's what we want to show you today

this is the the plastic pre-made pit

that we're going to put in so it's just

a big plastic bucket basically with a

lid that snaps on and then there's

access here for your pumper to your

lines to come out so this pit here is

approximately I think it's about two

feet deep and it's about two feet across

it actually might be close to thirty

inches deep so obviously before we can

install that we need to first of all

decide where we want it mark out the

concrete cut the concrete jackhammer it

out and dig the hole so so there's a

fair bit of work involved before you can

even worry about putting the pit in in

our case today we're actually relocating

an existing spot so I've already done

some of the cutting the old sump pit was

right here which was going to end up

being in the corner of a bed there of a

room in the basement and they didn't

want it there obviously so we're just

moving it over here a little bit to the

other side of the wall in this case

they've got I'm not even sure if you can

see it but there is a weeping tile

coming in under the footing into this

sump pit so we need to connect another

extension onto that and that will come

through a trench here and then cut into

the side of the the pail into this hole

okay and then the pump and everything

will go in it so so this video is

strictly on you know excavating this

hole and getting that pit set and in the

hole so so as I said I did do some of

the cutting already so basically what

I'm trying to do is cut cut down about

two inches or so just kind of a

perimeter of the of the area I want to

excavate this will just make a nice

clean edge for when weari concrete in

the surface again so we cut that chip it

out with a jackhammer

we had this smaller one here and the

concrete here is particularly hard so I

think we're going to probably go to a

bigger jackhammer just to speed things

up a bit but typically this hammer

probably would do what you need it to do

your first little chunk that you break

out with a jackhammer is always tougher

than then once you get that hole out

there and there's room for the pieces to

fall into but we are going to get a

bigger one I think to finish the show

the video so you can see I cut the

perimeter what I basically did I'm using

my using an old circular saw with a

diamond concrete cutting bit in it we're

going to use a vacuum to help control

some of the dust and a bit of water

obviously you need to be careful we're

mixing water with electrical tool so you

don't don't get too crazy dumping it all

over the place and end up shocking

yourself now the size of the opening

here like I said this pits about 24

inches across I allowed about 30 inches

just to give us a little more room to

dig we've got to dig fairly deep so if

you want to you want a little extra room

to work if you were cutting this

concrete with a grinder you could

probably cut a round circle if you

wanted to you know whatever whatever you

want to do but in this case I just cut

it sort of rectangular so our squarish

and that should do the trick so you're

going to need you know eye protection

hearing protection for sure like I said

we're going to run a shop back to try to

control some of the dust you may want to

dust mask though as well so we're just

going to continue on just finish off

this little piece here that we haven't

cut so far and it'll just take me one

second to get the vacuum and a couple

things into place and then we'll be

ready to cut

so you can see now when I plunged in

with the saw back here start to cut I

already had it started so it looked like

it just dropped in like nothing but it

will take a little bit of work to get

your first start to the cut you can see

I think probably in the video how the

vacuum does a good pretty good job of

controlling most of the dust you still

get some airborne you know you can set a

fan up on a window or something to to

try to suck some of the extra road and

then just splashing a bit of water along

here helps also again to settle the dust

and also cools the blade and assists in

the cutting process a little bit as well

so so we've got our cut all made I'm

going to squeegee some of this excess

water just off into the sump pit for now

and then we're going to get the bigger

hammer and start chipping this out okay

so we've switched out for a little

bigger a little bigger

jackhammer here there is a one bigger

than this yet that's still electric what

I'm pretty sure this one will do it now

you can see we've already started here

basically I'll just give you a bit of a

rundown on how to use one of these in

case you never have generally speaking

if you can start near an edge or a

corner is usually better and you know if

you're cutting like this you want to

start a couple inches away with the tip

so that you don't damage this and the

idea is want to try to get a hole broke

out and cleaned out a little bit so that

then when you start hammering back here

you know you usually come back a couple

inches from the edge and you know right

here I'd be putting the point and start

and you're trying to break pieces off

and now that this is emptied out the

pieces kind of have somewhere to go and

it works a lot easier from this point

once you have a bit of a hole started

yeah those are the main things it's

obviously going to be loud you don't

for most jackhammers the weight of the

jackhammer really does the work you know

leaning all your weight on it sometimes

is actually inhibiting it to work

properly you need a little bit of weight

on it and you're going to need to pry on

a little bit sometimes but for the most

part just let the hammer do its work I'm

going to have the wet/dry vac running

and that will suck up some of the dust

and also I'll be putting some of the

rubble in to pay

because we've got to peel it out of here

and get rid of it so basically I'm just

going to work my way through here and

we're probably going to speed up the

majority of it because obviously you

don't need to see all the seamy just

sweating my butt off working here so so

you'll see the first little bit here and

then we'll pro like we speed it up so

get on my safety gear and go ahead I've

just got the gloves on just pulling out

the pieces and that's kind of hard on

the hands so this particular jackhammer

just has a slide switch some of them

have a trigger this one's just a slide

and I should actually I should just

speak about the bits too so the bits

here come in and out by sliding this

there's usually a collar on here and

you'll have either a chisel bit or one

that'll come to a point usually and

usually the chisels going to give you

the most bang for your buck okay here we


so you can see that we've just both got

all the concrete broke out now this is

about probably a little bit over an

hour's worth of work to get it broke out

we probably got another 20 minutes here

by the time we have the bigger rubble

cleaned up and hauled out we've been

just using some old five-gallon buckets

filling them about half or

three-quarters full or whatever you can

easily carry you don't want to hurt

yourself we've got to carry it upstairs

and outside so we're going you know not

right full and you can tell I'm out of

breath so we're just going to get this

rubble out of here and then we can start

digging down and we're going to

basically save most of this fell onto a

tarp and reuse it a lot of it around the

around the new pit and stuff itself one

thing that probably worth mentioning is

before you start a project like this

there's a few things you should consider

about in the area that you're going to

cut the concrete or start digging one

thing is if you have in-floor heat like


hydronic heating system inside your

concrete obviously you cannot do this

job you're going to end up cutting a

pipe for sure so don't don't even

consider it another thing to think about

is where all your plumbing is coming and

going from in the basement because it

will be below here and sometimes it can

be quite shallow just below the floor so

that's your any kind of drains from the

say the bathroom plumbing your main

sewer going out although it should be

pretty deep you shouldn't shouldn't have

to worry about it and the main thing

would be your main water line coming in

so if you kind of know where your water

meter is in the house and you know

basically where it comes in from outside

then usually it's straight away from

there so make sure you're nowhere near

that area because that that one can

flood your house pretty quickly before

you get the city there to shut it off so

so you think about all those things

before you start this kind of project

but if if you know you're out of the way

of any of that stuff and you're good to

go then you know break up your concrete

and start digging okay so now we've got

all the comp main concrete out of the

way we can dig this hole down remember

where we got to dig a big enough hole to

sink this barrel into so it's going to

be a fair bit of digging we're going to

need some of that what we get out of

here some of the best stuff which would

be the gravels and stuff that are on top

to fill back in around it so I'm saving

that onto this tarp to reuse it and if

we get down to some clay or whatever I'm

going to try not to reuse most of that

so it'll get in the buckets and hauled

out again so pretty basic we're just

just going to be shoveling here for a

while to get rid of this stuff here so

you have a hole to put that pit in

pretty basic straightforward just keep

digging so they've got a nice amount of

gravel in there

that's good okay so I got all the

digging done you can see this massive

crater that I've created here and you

can see there's already some groundwater

just seeping back into it that holes

been dug for about half an hour so you

can also see that I've got this

extension for the weeping tile and in

our scenario and it's just simply slit

both both the weeping tile coming into

the house and this extension are just

slit and the two are just slid over each


preferably this one slid over top of the

other one to help keep directing the

water this way this trench was created

here with just ever so slight a little

bit of a little bit lower at this end

than it is here so the water will

naturally flow to this to the bucket so

for the most part all the digging I just

did with a shovel you can see I have

quite a massive of backfill here some

clay and some gravel most of most part

did with the shovel I did bring this

post hole digger here in the end I

didn't need it had enough room to work

so I didn't worry about that so we've

got that all in I've got my side of my

bucket cut open and that's just

determined by the elevation of the pipe

so I've got that cut that isn't a tight

fit the pipe easily slides through there

with room to spare so so basically just

a matter of putting your bucket down in

the hole redirecting your pipe into it

like that now when I was digging the

hole I just used a straightedge I wasn't

really going for level I'm just using

this as a straightedge you know going

from floor to floor from concrete

concrete and getting the bucket

I don't want it standing up so like

above the floor if anything I want it

down just a bit and I'm probably a

little quarter inch lower than the

concrete here so it's just a matter of

getting the bucket sitting in there

so that the straightedge isn't riding up

on it sometimes just stepping down in

here I'll just settle it down into that

hole a little bit okay so there's no

real science to that just get it down

below the surface of the floor and once

you've got your pipe all in there just

be sure it's laying down nicely you

don't have a big hump in the middle or

anything we'll just make sure we put

some weight on this when we start our

backfill to keep that Center down it's

sticking into the into the pit itself

you know an inch and a half or whatever

and we're pretty much pretty much ready

to just backfill that so I'm going to

put a little bit of clay our our

extension of our weakened tile doesn't

have any grooves in it it's a solid pipe

so we can put clay right on it we don't

have to worry that the groundwater is

going to beep dirt into that so so put

some clay here we'll try to get some

sand in so gravel back in around the

little bit of space that's between the

this liner and the hole will be dug and

you know a little bit of clay a little

bit of gravel get it up to great where

we want our concrete and then we're

ready to go okay so like I said before

we're going to backfill over the pipe

mostly with clay we're going to use some

sand around that little gap around the

bucket around the liner I did take a big

pail of clay just a five-gallon pail and

set it down in that liner just to hold

it in place so it isn't moving around

while we're doing any back filling so

just get some of this in here that's

great I want to stand on there too

once you have some weight on there

basically holds that down

okay I just want to get some gravel

around there around that pit

okay so that just kind of gets our pit

sitting stable so it's not shifting

around in that hole on us now we'll use

a little bit of this clay to take up

some of the bulk


so once I've got the clay kind of

roughly in there I just want to pack it

down get it settled down clay isn't the

best backfield material but here we're

not structurally holding anything so I'm

just using this would basically just

pack that down in there okay so we

finished our back filling we got the

gravel in there we tamped it down with

the board and then I walked around in

there just to pack it down that much

more swept the area around us here just

to get rid of any stones that are up on

the concrete more than anything just

keep from kneeling on them that sort of


I also ran the broom around just on the

inside edge here you know there's some

little lips and stuff because this isn't

going to be perfect and just swept off

any sand or gravel that was up on there

too so we get a little bit of bond there

I'm just mixing the bagged for kind of

pre-mixed concrete for this little job

and probably only mix about 1/3 of a bag

at a time because I'm just mixing it by

hand in this pail but basically just

going to mix it dump it in there we'll

prod it in nice with the trowel and you

know then work our way around but we'll

we'll get ourself worked fair ways from

that side there and before we start

trialing or doing too much messing

around so just mix it as you're as the


tell you two for the manufacturer

it's not the easiest to mix it just in a

pail but for this a little bit that

we're doing I'm just using a little

paddle to try to make sure I mix and

rake down to the bottom it's not quick

real quick setting or anything it sets

relatively quick but it's not like I've

got to be a huge panic here just trying

to get smick straight down to the bottom

I probably put a little more than I

should have been here to start with okay

this batch is a little runny because I

added a little more water to it than I

know they wanted to but I don't know if

I mentioned we're basically trying to

leave about three inches of concrete

around there we didn't do any rebar

dowels or anything but you could dial in

rebar if you wanted to a lot of this

floors in this section here is barely

two inches so if I try to anything in

there it's probably just going to break

off anyway so

so we're just pouring it around there

it'll kind of run where it needs to run

and like said we'll do some traveling

here after a bit

so I'm going to set up a little bit over

here I'm just kind of basically

vibrating it down into there and hard to

deal with a little little area like this

let's go around and basically slope it

to whatever your pits at okay so you

just kind of my in my case like I said

before my pits about a quarter inch low

so it just creates a little bit of a

gradual slope back

just kind of hope my weeping tiles

already left simple harder on our so you

just kind of working it a little bit

kind of gets the air out of it that

might be trapped in there I'm just using

a magnesium float for this part girlby

was a little bit runnier than it really

needed to be a little bit more to finish

off there

okay so a little bit more just to finish

this hairy off here let's see my kid is

just a little bit offset that way the

center of the hole so put a little bit

more width over here on the concrete

you'll get once this dries you'll

actually get a little bit of shrinkage

and you'll probably get a bit of a crack

around the perimeter from the old pad

it's in a fits in a floor where you want

to you know maybe you're putting some

vinyl or something like that

once this cures then you might want to

go over it with some self-leveling

cement just to kind of smooth it out

anywhere where it shrunk so with the mag

we're not trying to get it perfect but

trying to get it pretty close and we'll

use a steel trowel on it once it sets

off a little bit more a little bit of

time yet so I'll just keep filling in

this trench with the concrete and then

we'll come back to this okay so once the

concrete has set up a little bit further

we're going to use a steel trowel on it

we use the magnesium float before and

that's basically just to get it pretty

much into place it helped pull up some

of the fines to the top and then the

steel trowel once once your bleed waters

have kind of come off the concrete you

know the moisture that leads through

then you can should be ready to trowel

it and this will just give it a little

smoother finish

close in any this is actually still a

little bit wet we're just kind of

flattening it out with this and you can

see how it makes a smoother finish than

what we've got over there that we did

with the magnesium trail a little hard

on a small area like this when we poured

it in different batches ones drier ones

wetter than the other so it's all

setting up just a little bit differently

but I'm just going to go around this

main pit area I know down there it's not

going to be ready for the steel because

it was poured later but I'll just go

around here a little bit tricky in such

a small little area here but and also

before I did this I went around the

edges and just kind of cleaned up any of

this a little bit of piece that's around

the edge sometimes there's a rock in

there so I just clean it up with the

edge of this before I get to there okay

that's about as far as I can go over

there we just kind of work that edge in

as good as we can it's not the easiest

thing to do when you're coming up

against a cut so that pretty much really

is the wrap for that this video we will

be doing a separate video on actually

installing the sump pump so you'll want

to check that out as well we're it's

actually going to be a 120 volt with a

12 volt backup so look for that this is

all basically complete the concrete just

has to set up though and and that before

we can do the pump so

so hopefully hopefully this worked out

alright and gave you enough information

to maybe install your own sump pit and

you kind of know what tools you're going

to need and what supplies you're going

to need as well so if there's any other

questions you have about this just go to

our forum on the website check us out

there and post up any questions you have

you can follow along with us on Twitter

and Facebook and also you might want to

check us out on our patreon as well so

good luck with your project and we'll

see you next time
