Never mind I found it.

How do I download the app? I went to the google+ site and can see all the comments and I am a member but I could not find a download link.

When my stenner quit pumping it turned out to be the inlet side tubing adapter leaking. Try this - unhook the inlet side tubing and put your finger over the tube inlet and turn on the pump. If the tube is not leaking you will feel some suction pressure on your finger if the tube is leaking...

I use the the 100 psi model mainly because it comes with a check valve on the discharge line where it feeds into the main pump return line. This allows you to unhook the chlorine discharge line and measure the output without shutting down the main pump. My Stenner is two years old and it has...

Thanks for posting that spreadsheet. It agrees very well with my actual measurements.

The only thing I know of is to reduce or completely shut off the flow to the tail. Mine does the same thing - in fact it just sprayed me a minute ago. I just live with it.

Yes, the booster increases the pressure coming in by a fixed amount. So lower pressure on the inlet means lower pressure at the outlet. If you are getting DE and debris from the filter the polaris inlet screen is likely plugging up and reducing flow to the cleaner.

Have you checked all the tubing and swivels for leaks? Whenever my polaris stops moving as fast as it should there has always been a leak somewhere or the filter needs backwashing. It does not take much of a leak to slow it down. I've had leaks in the back up valve housing, swivels, PRV, and...

Re: 'Debugging' Polaris 380 (lack of) wheel RPM - next steps? The whole valve will unscrew and come out. Then just screw in a 1" PVC plug. I doubt a rubber stopper would stay in place very long.

I ended up making a frame out of 1" PVC that goes around the bottom and both sides then attached it to the ladder with SS hose clamps. That works very well and cured the problem. It's also very cheap and easy to make.

Try removing the relief valve and replace it with a plug. Several people including me have had to do that to get the cleaner to travel as fast as it should.

Re: 'Debugging' Polaris 380 (lack of) wheel RPM - next steps? Put your hand around the relief valve and see if you feel water coming out. Polaris has a lot of trouble with these valves. I had the same problem as you have and found the relief valve was passing so much water the cleaner was...

My Stenner tank hold 25 gal and I buy chlorine in 2.5 gal carboys. I made myself a dip stick from a garden stake by cutting a saw kurf in the stick after adding each carboy. Now it's easy to tell how many carboys the tank will hold.

It does not take much iron to turn HCL yellow. Before I retired I was involved in the design of three chlor/alkali plants. It was a joke in the plants that some customers thought a yellow color in the acid meant it was stronger so the plant would drop 4 or 5 16d nails in a tank truck of acid...

Just a quick update on my pH/alkalinity/acid addition problem. I lowered the alkalinity to 40 ppm on the 26th of July while aerating the pool. The pH rose to 7.4 - 7.5 on the 29th and I stopped the aeration. That was 7 days ago and the pH has remained stable and is still 7.4 - 7.5 today...
