Of all the features associated with inground swimming pools, attached spas almost certainly have the most complex designs. Achieving proper hydrotherapy-jet action requires the interweaving of air lines, water lines, fittings, jets and associated pumps, blowers and motors in a way that delivers results the customer wants and expects. And making mistakes is definitely costly: Once the plumbing is set in concrete, there’s no easy way of turning back. The bottom line: You have to

It's a high-stakes game, but all too often I see pool builders take an ill-advised roll of the dice by not doing the work ahead of time to make sure the
