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.
