I'm currenty digging out dirt around my pool to replace with landscape rock.
I am planning on installing the following items before putting down the
Plastic or fabric weed blocking material.
Grey plastic electrical conduit (for waterfall or fountain pump and pool
A 1 1/2" PVC line for my pool backwash.
Landscape lighting wire.
Plant drip line.
Should any (or all) of these items be installed under the weed blocking
electrical pvc should be a minimum of 12 inches below grade. Low voltage
wiring might be less of a hassle under the plastic. Less chance for the
rocks to penetrate.
As for the 1 1./2 in pvc, go with 2 or 2 1/2 inch if you install any 90
degree bends. the longer you push the water the harder it is for the pump.
I used 3 1/2 inch perforated just below grade, something like 40 feet of it.
I wished that I had used 4 inch and more like 60 feet then I would not have
to see the water at all.
I have never installed a drip line, only ripped them out.... just covered
He's not using the PVC for electrical. He's just making a permanent line
from his pool filter (instead of using rubber or plastic hosing) to
carry off dirty water when he backwashes all the crud out of the filter.
And I don't think he has musch to worry about with the wiring. It's
outdoor stuff is pretty durable as it is, except maybe for the speaker
wire being less durable by comparison. But unless he's using lava rock,
there really isn't too awful much to worry about as far as penetration
goes. It *could* happen, but not likely.
You could bury everything under the weedblock to make it all nice and
tidy, but you face the possibility (and given Murphy, the eventual
probability) of sooner or later having to uproot one or more of those
lines up to work on something that futzed out on you.
If you're laying down enough stone, all those lines should hide well. If
they get exposed from feet and paws and such knocking around the stone,
just move the stone around with your foot to re-cover the exposed
portions. But mostly, if you have to uproot anything, you'd only have to
just move the stone over instead of pulling up all that weedblock to get
I'd go with just burying it under the rock.
Thanks for the help. The old stuff I'm digging up had the landscape
lighting wire on top, the drip line under, and the pool light line was
direct bury romex-like stuff. Bad choice on that one. The jacket was
almost completely decomposed.
I just hope I can find the juction box where the pool light cable meets the
120 line from the timer box. I've heard that they usually bury them
directly behind the pool light on the other side of cool deck. I hope not.
Theres a double 24" diameter palm tree stump there.
I would put everything below and I would run some plastic irrigation pipe
where you want the speakers and low voltage stuff along with a pull sting
then if you need to add or replace anything instead of digging stuff up you
can just pull it. It will also protect the wiring from an errant shovel in a
