Nordic Spas with Ozone - Check This!

[Rask]

My Nordic Spas Warrior XL was finally delivered a couple months ago after many delays.  The weather has been rainy, but with spring arriving things have dried out and I noticed some seepage around the bottom of my tub.  I opened it to find 1/8 to 1/4 of water standing inside the base of the tub, and water dripping from a port on the sanitizing system.  I looked up the installation manual for the Ozone generator they used in my tub, and it specifies that the ozone injector tube must be routed with a check valve above the water line.  On my tub, this was not the case and the check valve is below the line of the top jets in my tub.  Water is backing up through the ozone injector tubing and dripping out the port at the bottom of the ozonator.  Clearly this is an installation issue by Nordic. 

I contacted Nordic to let them know about this problem while waiting for a callback from my dealer.  I was polite, explained the problem, and sent them photos.  They responded stating that all of theirs are installed with a check valve above the water line (obviously not true as mine is below the top jets) with a snarky comment about not opening parts under warranty and to contact my dealer.  Since their attitude was not one of wanting to understand so that they could correct the installation problem on future tubs they build, I thought I would let folks who purchase a Nordic tub with Ozone to check that it is installed correctly and not dripping.  You can see this just by opening the service door.  If it is dripping, this should be corrected by your dealer re-routing the ozone injector tubing up higher with a check valve above the water line.  

I will update when the technician comes out.

The photo you posted looks to be on the intake side of the unit. Yes there is a $.29 check valve that has failed but it is not where you are showing. There should be a 3/8" or 1/4" line on the other side of the unit attached to the check valve that has failed (at bottom of attached photo). There should also be a "Hartford Loop" see below to prevent the water from back tracking. This is the part that needs to be above the water line. The top of the loop. If the ozone is not tripping the breaker replace the one way check valve and make sure the top of the loop is above water and good to go.

Yes, what you have explained is how I understand it as well.  The previous post only showed the drip.  Here is a photo that shows the ozone injector tube and the check valve.  I didn't post this originally due to Nordic's comment about potentially voiding my warranty by opening equipment, but according the ozone manual this check valve is a serviceable part that is supposed to be replaced once a year and there was no seal or warning on the cover saying not to open it. 

As you can see, it is not looped up above the water line.  There are no holes in the cover for the tube to be routed upward in a hartford loop.  My guess is that the whole unit is intended to be installed higher.  One could drill holes in the plastic cover and create loop easily enough, but since its under warranty I will let the service tech fix it.

According to your diagram, the ozonator should be installed higher.  While I noticed that the labels on the unit are upside down, I just assumed it was installed intentionally this way.  But if it was installed rightside up, that ozone unit would be much nearer the water line as in your diagram. Is it possible the whole thing was installed upside down by mistake?!
