Nordic Spa Plumbing Parts

Some Nordic hot tubs have shut-off valves on either side of the spa pack/pump to allow for servicing the spa without needing to drain it. Spas can have 1" flex hose, 1 1/2" flex hose and other plumbing components including slice valves, tees, 2" heater tailpieces and even a drain spigot.

On single pump systems, this slice valve is on one side of the spa pack and the other one is located after the pump. On two pump systems, there is another set of slide valves on either side of the second pump.

1" Slimline air controls are used to add air into the jet water flow.

Replacement hot tub jets include Mini-Storm twin jets, Poly Storm foot jet, Power Storm twin roto, Power Storm rifled, Power Storm, Poly Storm Massage and various cluster jets among others.  There is even a turbo/whirlpool jet in some models that provide high volume water flow out of a single jet nozzle.

A popular turbo jet is the Hydro Air Whrlpool diverter jet.  In addition to 1 inch slimline air controls, some of these spas also used 1/2 inch slimline air controls.  The jetting was different too including: Micro VSR Whirly, Micro VSR directional, Micro Blaster, Large VSR jets and Duo Directional jets among others.

Hydrotherapy jets used in Nordic spas are recessed and located in the wall above the seats. Rotate the jet face counterclockwise to turn the jets on and clockwise to turn the jets off.

We also offer the Slimline air controls if needed. Contact us at with pictures of the parts you need or with details about which Nordic hot tub part(s) you are looking for and we will respond quickly with the correct information or ask you for further details.

Nordic hot tub jets not working?  First be sure the problem is not water flow to the jet.  This could be anything from an air lock in the plumbing to a clogged filter.  If flow is low to a group of jets, then chances are the manifold in the plumbing system that is feeding that particular group of jets is not getting enough flow.  Is the pump working properly?  If there is a service valve in the plumbing line, is it all the way open to allow for unrestricted flow of water?

If the jet is adjustable, then simply turning the ring around the edge of the jet can open and close the flow to that particular jet nozzle.

If you do need to replace the jet(s), contact us and we will help you identify the correct jet model for your hot tub.

Nordic Hot Tub Control System

See our complete selection of Nordic Control Panels.

nordic panel controlThere are several different control panels available for Nordic hot tubs.  The hot tubs that use the Balboa v41 system can use different versions of a 4 button Balboa control panels. The buttons include Warm Cool Light and Jets.  There is also a 6 button oval panel with Jets 1, Jets 2, Light, Warm, Cool and Mode buttons.

Newer spas use the Balboa control systems for 120v and 240v controls. There are also some older spas that use Balboa Digital Duplex controls (pre-2000).

Older Nordic spas use the Gecko control system such as UC-CF single pump systems. Some of the plug and play spas can be converted from 120v to 240v by moving Jumper 1 to HC mode so that the heater can stay on when the pump is on high speed when operating the spa at 240 volts. 

Older topside control panel models include rectangular controls with 4 buttons (Jets Light Warm Cool) and also a 5 button panel for older 2 pump systems (rectangular). There were even unique rectangular control panels with a rounded edge on the right side of the panel.
Newer Gecko control panels in the oval style are also used.  We carry all of the 4 button and 5 button, 1 or 2 pump replacement control panels for Nordic hot tubs.

Chemicals for Nordic hot tubs

The manufacturer recommends monitoring pH and to use chlorine as the sanitizer along with an ozonator.  It is also recommended to clean the cartridge filter every two weeks to remove particles and lodged objects within the filter pleats.  Use a garden hose with a pressurized nozzle to push water from inside to the outside of the pleats.  Once the cartridge is too dirty, an overnight filter cleaning solution is recommended.
