Jets from the Poly Storm range all have a length between 110 and 115 mm and a front-facing diameter between 85 and 100 mm.
A jet has two parts:
A socket or jet body, which is fixed on the spa's shell and connected to the water circulation system.
The jet itself, which fits into the socket.
If you want to change your jet (find the same one or change the massage type), check the style of your old jet, snap-in or thread-in, since they are not interchangeable. Once you have identified which type of Poly Storm jet you need, you'll have no problem finding and replacing it with any Poly Storm jet of the same type.
If you cannot find the jet you need, feel free to contact us (and to send us photos with the size of your jet, if possible) of the model you're looking for, and we'll try our best to find a compatible jet.
Note: Waterway has recently redesigned the back of its Poly Storm jets (see photos below). The two versions are completely interchangeable.
