Manifolds for hot tub plumbing
A manifold is a common hot tub part that is used to divide the flow from a pump across a large number of jets. We refer to manifolds according to the size of the fat pipe, which is connected to the massage pump, and the number and size of smaller pipes, which go out to the individual jets.
We offer a wide variety of sizes and configurations! If you are replacing an existing manifold, check the sizes of the pipes that it connects to. The most common configuration for water jets is a connection to a 2" or 1.5" manifold using 3/4" pipe. Air jets are usually connected to smaller manifolds, typically 1.5" or 1", using 3/8" pipe.
We use the following abbreviations to help you find the right manifold:
