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” flex or PVC lines for your suction, in- take, and air line. In ground spas have marked intake and suction lines, making it easy find 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 efficient, 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.
