Plumbing Connections
IMPORTANT! Always check local codes prior to any
inground spa installation.
Once the spa and equipment are properly located, you
will want to lay out the plumbing run.
Trenches should be deep and wide enough to allow
all pipes to be buried below the frost line and should
be in as straight a line from the spa to the equipment
as possible. Check local code requirements for under-
ground pipes. Always know what is under the ground
before you dig anywhere.
You will need 2” ex or PVC lines for your suction, in-
take, and air line. In ground spas have marked intake
and suction lines, making it easy nd and connect to
and from the spa and equipment pack.
The plumbing run should not be any longer than 15
feet to maximize water pressure. Another way to max-
imize water pressure is to limit (or even eliminate) the
use of 90˚ elbows in your plumbing run. A more direct
plumbing run using 45˚ elbows is more efcient, and
promotes increased water pressure.
Identifying Plumbing Lines
The spa’s plumbing lines are clearly marked during
water testing at the factory. This is done to assist in-
stallers in properly identifying the installation. We still
recommend that the installers verify plumbing lines
prior to gluing. This can be done by using one of the
following techniques.
Air Test
The air test requires a wet/dry vacuum. Locate the
plumbing line you wish to identify and secure the vac-
uum hose to cut open end. Turn on the vacuum, enter
the spa and listen for vacuum suction sound from in-
side the spa side lter canister. If you hear the suction
sound in the canister, the line is properly marked and
can be connected to the suction side of the pump on
the equipment pack.
Water Test
The water test requires a garden hose and water
source. Locate the plumbing line you wish to identify
and secure the outlet side of the garden hose to cut
open end. Turn on the water supply to the garden
hose, enter the spa and look for water inside the spa
side lter canister. If you see water in the canister the
line is properly marked and can be connected to the
suction side of the pump on the equipment pack.
If any plumbing line is not properly marked or not
marked at all, follow either the air or water test proce-
dure until all lines are identied prior to gluing.
NOTE: Once complete, water test the plumbing run
for at least three days prior to covering any plumbing
trenches and back-lling spa cavity completely.
NOTE: Some local inspectors require pressure test-
ing the plumbing lines. Although the spa is pressure
tested at the factory, local inspectors may insist on
pressure testing the plumbing run between the spa
and equipment pack.
