Shipping T&Cs

I'm not sure what I need. Can you help?

Please try our Search first— try entering any part numbers, models, or measurements. There’s a good chance you’ll find it! Still can't find it?

We’re here to help. For the fastest, most accurate response, please include:

Clear photos of the part itself and where it sits in the spa (control box, touchpad, pump label, filters, etc.).
Measurements (e.g. thread size, pipe OD/ID, heater kW rating, pump label details, etc).
Brands: Mention any brands you know or can see.
Error codes or symptoms you’ve noticed, plus anything you’ve already tried.
Technical Help - For technical assistance, please email us with as much detail as possible. Keep in mind we are limited in what advice we can provide on electrical and gas components, as all work must be carried out by a qualified technician.
