A&A Tsunami Valve Eating Gears

[Rocketman240]

I have a 6-port, low-profile Tsunami valve for pop-up in-floor cleaners in my pool. It uses a gear-set like this one: (https://www.amazon.com/Manufacturing-540277-6-Port-Low-Parts/dp/B00HEAPGZ8).

It’s eating the small pinion gears so much that I need to replace them every month or 2. Has anyone seen this before? Know the root cause? I’m guessing that the bowl is out of round and causing too much friction / gears to bind. Thoughts?

Welcome to TFP.

Are you using genuine A&A parts?

Let’s see what @proavia thinks.

Yep, all parts are OEM.

Are you the original owner?
If so, you should have a lifetime warranty on those parts.

Contact A&A (now Pentair) and ask what might cause your gears to fail so quickly.
Something isn't right as the gearset and gears should last for years.
Time how quickly the IFCS changes from one zone to the next and report that here.

Post a few pics of your water valve as an assembled unit and with the top off.
You can also take measurements of the diameter of the lower housing gear from several different data points around its circumference to check if it's out of round.

Unfortunately, I am not the original owner.

Valve to valve on time is about 14 seconds at 3200 rpm on the pump.

Measurements around the top of the bowl with the top off are all very close. I don’t have calipers with jaws big enough to get a measurement at the height of the gears.

I appreciate the help!

14 seconds to change from zone to zone is WAY too fast.
90-120 seconds is average.

With the side feed low profile valve, you can regulate flow to the impeller by rotating the lid. The lid throw is limited, be you can bypass the impeller flow satisfactorily.
