- Welcome to "Swim University".
My name is Matt and
this is my friend Dave.
- How you doing?
- And we are going to change the sand
in his sand filter today.
Now I guess it's been,
what, six years since--
- Six years.
- Yeah, since we've changed
the sand in the sand filter,
and over time, the sand gets,
it loses it's coarseness,
so it doesn't filter as good.
So, are you ready to change the sand?
- Let's do it.
- Let's change some freaking sand.
(surfer rock music)
Okay, before we start,
we just need to go over a few
things that you're gonna need,
in order to change the
sand in your sand filter.
One, you're gonna want pool sand.
And not just any sand, not play sand,
but pool sand, or filter sand.
A screwdriver.
A shop vac, or a big plastic cup,
in our case we're gonna use a
shop vac today, and duct tape.
First step is we're going
to remove the drain plug
and get all the water out of the filter.
So, yeah, let's remove that.
And we're gonna let that drain for,
whoever knows how long it takes to drain.
All right, next step is we're
gonna take off the collar
of the multiport valve,
and then we're gonna
remove these unions here.
So let's pop this off,
there's two screws here
and we have an electric screwdriver.
- I'll take that.
- Yep, collars off, now we're
just gonna unscrew the unions.
This particular filter
had unions in there,
so that's beautiful we
don't have to cut any pipe.
So we're just gonna unscrew these unions.
So that way we can remove
the multiport valve.
Now you wanna be gentle here,
because there's laterals at the bottom,
and these laterals can break
under the pressure of the sand.
There you go.
There you go, cool, cool.
Cool cool cool.
We're gonna cover the top of
the standpipe with duct tape,
so that no sand gets inside the pipe.
If it does that sand goes
right back into the pool.
There we go, cool.
We got the shop vac hooked up,
and we are gonna suck some
sand out of this filter, so.
(funky music)
- This job really sucks.
- It sure does.
You wanna take the standpipe, lift it up,
check the laterals make
sure that they're all good,
nothing's broken, you don't
want any broken laterals,
if you have broken
laterals sand will get back
in your pool, guaranteed.
So check it down, we're
gonna rinse it down.
We're not gonna take the
laterals out of this filter.
They're a little tight and
they're hard to get out.
So we're just gonna leave it in there
but rinse it down with
a hose, clean them out.
Get the rest of the
sand out of the filter,
and then we'll go from there.
Now we're gonna fill
the tank full of water,
halfway full of water, actually.
So we're gonna want to
replace the drain plug
back onto the filter.
So that way, none of the
water just comes seeping out.
And we're gonna grab a hose
and fill this thing halfway full of water,
make sure the standpipe is
centered, inside the tank.
Happy Father's Day.
- Oh thank you sir.
- You're welcome.
- It's always nice to be
working on Father's Day.
- Yep.
One thing you're probably gonna need
in order to do this trick, is a knife,
which is, it's a pretty badass knife.
- I'm a badass dude.
- Yeah.
So we're gonna cut the bag,
and let the sand just
pour into the filter.
Now we have, this filter
takes 350 pounds of sand,
so we're gonna be doing this--
- Seven times.
- What, seven times, yeah.
And away we go.
(rock music)
Dust and debris is
flying out of the filter,
don't breathe that in, if you
have a mask wear it unlike us.
We're pretty awesome, so we don't have to,
when we breathe it in it
helps us, our immune systems.
No that's not true.
All right, we're gonna remove the plug.
We actually replaced it with,
the tape wasn't really
working out to well for us.
Pop this back on.
Now, just so, we just checked the o-ring,
you want to make sure the o-ring,
before you put it back on,
is in good condition.
Just bend it in your
fingers, and if you need to,
just add a little bit
of lube, and that's it.
So all right, let's pop it back on.
There you go, there you go you got it.
We're gonna pop the o-rings
back in from the unions.
Make sure those are
also in good condition.
Now we're gonna put the clamp on.
There you go.
All right, putting the backwash hose on.
Little handy tool ya got there.
- It does the job.
- All right, final step is
we're gonna backwash this filter
before we get it up and running.
So let's turn it to
backwash, there you go.
And pump that filter on.
(filter running)
We're gonna let this run for
about two minutes on backwash,
just to make sure this whole
filter gets cleaned out.
And then the next step we're gonna do is
we're gonna actually rinse it.
The sight glass is showing the water
that's coming out of the filter.
So, once that runs clear,
then we know that all that
debris and stuff is out
of the filter system.
All right, now what we're
gonna do, is we're gonna turn
the multiport valve
from backwash to rinse.
And we're gonna let
this run for one minute.
Final step, is we're gonna
turn this thing to filter,
and we're gonna be completely finished.
One little turn, boom.
What you want to do is make sure,
the pumps primed, let this thing run,
and we're gonna take a look at
the pressure gauge over here.
And whatever the pressure
gauge is running at,
that's your normal pressure that you're
gonna always want to keep it close to.
Now the pressure is a little over 10 PSI,
which is beautiful.
When this goes about,
10 pounds over that particular pressure,
is when you're gonna want to backwash it.
All right, we successfully
changed the sand
in your sand filter,
it's running at 10 PSI,
it's got good pressure.
As you can see the waterfall's
running, looks beautiful,
and that's it, so, we're all done man.
- Thank you sir.
- No problem.
- It's been great.
- Absolutely.
- Nice and easy.
- Yep.
