Question about Waterway Spa Jet - Poly Jet Internal Pulsator Smooth - Black

Open Question

No air from Waterway Poly Jet, just water

I installed a pool spa last year. It has 8, 210-6090 - Waterway Poly Jet Insert, Deluxe Series Roto, and I believe was installed with 210-5860 1"S Air x 1-1/2"S Water, Tee Body 1" PVC Air, 1.5" PVC Water. When we started the pool initially we did not hook up a blower. The movement of the water created enough vacuum to pull air into the air inlet pipe and the spa had "natural" bubbles without forcing air into the air lines. It worked that way for the entire season.

I noticed during the season that some of the jets wouldn't turn and flow was restricted in some too because of construction dirt in the jets. At the end of the season I removed all the jet inserts, replaced them with the required manufacturers plug. Over the winter I took them all apart and cleaned them so that when I opened the pool all the jets were free of the dirt and rocks and they all worked and spun perfectly. They still do.

My problem is that for some reason I lost the natural air flow. In fact, the water now seems to be backing up the air line when the pool spa is running. I've tried draining the spa, and restarting it. I even tried hooking up the return line from my shop vac. As soon as the water pressure builds, the water backs up and cuts of the air from the air intake lines.

What did I do? Is there a way to get this back to it's original working order?

SOURCE: I just bought this pump

The wear ring on the impeller can cause all these problems. It seems natural to put this on the impeller with the wide side tward the impeller but it goes on with the wide side out so when the pump starts the ring slides forward and seals the pessure side of the impeller from the suction side. With this in wrong your water will just circulate inside the pump rather than going back to the spa. I hope this helps.

SOURCE: I just installed a Waterway Above Ground Hi Flo

sOUNDS LIKE ONE OF TWO THINGS.

1) The pump is cavitating (sucking in air) could be not enough water flow to it, or a leak.
2) The bearings could be bad or misaligned

SOURCE: I have a Waterway SVL56

That means that the connection between the motor and the actual centrifugal pump is broken. This is terminal: replacing the broken part will cost you more than the price for a brand new pump. Just cut your losses and replace it.

Sounds like you don't have the pump lid "0" ring seated properly under the lid, or there is dirt or leaves on the "0" ring. This has to seal perfectly or the pump will not pump much if any water.

SOURCE: Waterway pump not priming

Foam will definitely keep a pump from priming. Why do you think it's the calcium causing the foam? I have added large amounts of calcium to pools and I do not recall ever having any foaming issues.
Check to see if your impeller may be clogged. Take the lid off of the pump and fill the basket up with water. Leaving the lid off, start the pump for three seconds and then turn it off. The water should be sucked away almost instantly. If the water level drops slowly you have debris clogging the impeller. If that is the case the pump needs to be opened and cleaned.

The water jets in most spas are adjustable so you can turn the water flow down to just a trickle if you want to.
You don't take current spa jets out of the spa. They are held in place by a couple of tabs. Through the years the chlorine/bromine will deteriorate those tabs and the spa jets will start "popping" out when the jets get turned on.
If you pull the jet insert out the socket they are in, you will ruin the jet insert and it will need to be replaced.

Can I use vinegar in a hot tub as a descaler


I would advise against vinegar. It is a weak acid which may have an adverse affect on your plumbing, spa & jet surfaces even if you intend on draining the spa for cleaning.
I doubt it will be able to cut the mineral build-up anyway.

Here are two ideas Scale preventer or Jet Cleaner which work well on acrylic spa's. Just check with Roto-Dreamaker first to see if they will be okay on their plastic.
If you want to try something else before buying those try using a mild non-abrasive, non-sudsing cleaner with a soft cloth or nylon type scrubber to the build-up. Also try baking soda either option should be okay for the plastic.

The cause of the build up is not usually owner related but the water chemical composition in your area. Your local pool/spa store will have the best advice for your local water chemistry.

I discovered tiny ball bearings in my hot tub. Where could they come from? The hot tub is working fine.


The ball bearings from your spa are from a roto head jet. Typically they are from one of the larger sized jets and they make the swivel action in the roto swirl jets function smoothly. You can determine which jet is coming apart by the loose function of the center nozzle. The jet can be removed and replaced to solve this problem. Most jets screw out but when they have deteriorated a lot, you may need plyers to take the jet out in pieces.
