Half Jets Are Not Working

[jgill]

I have rapidly reach the limits of my competence. I’m a new pool and hot tub owner (both came with the house I purchased in April). I have not touched the hot tub until the last several days. The previous owner said something was wrong with some of the jets but didn’t know and didn’t want to fix it. The hot tub is a Nordic Encore.

So fast forward to two days ago and I started my investigation into this hot tub. First, I drained it, cleaned it, removed the jets, cleaned them, removed the filter and cleaned it, so on and so forth.

This afternoon I filled up the hot tub from the filter port to avoid air pockets (which it appears I did). I got the water level to the appropriate level and turned on the pump. Only to find that two of the seats and the lounge seat have weak water pressure while the rest has strong water pressure.

This is where I am completely stump. I do not believe it is the pump as I have strong pressure on three of the 6 seats. Any help would be appreciated. I’m trying to avoid calling in a “professional.”

Maybe @RDspaguy can point you in the correct direction.

Arm yourself with some Amazon.com Ahh-some that and spa cleaner.

Most jets are adjustable at the face. Are they all on.
Many tubs have a diverter valve that switches water flow from zone to zone. They are usually on the top edge. Old ones can stick bad.
Air control valves (also on top) allow air to mix with the water causing them to feel and look more "powerful" but do not actually change pressures.
Many tubs have multiple pumps, and a pump issue could be the cause in that case.
Some pics might help.

Thank you for your reply! I went searching and found the diverted valve, which was actually in the water, as an outlet.

All is working great. I’ve order some Ahh Some and am going to do the TFP method on this hot tub as well.
