Thought some more on this. Having changed the freeze temp threshold this winter, I figured I might have mixed up an Aux1 setting in the process, so I verified the Aux1 settings were correct. Then I removed the control logic circuit board using a T6 Torx bit and cleaned all contacts with...

I am not sure what your first question is after, I only have one primary pump. But as for the second, I use "Pool & Spa Lube" .

Thank you for the suggestion. I tried this, nothing happened.

After 7+ years with a Hayward T15, I ran comparative analyses ($/pound chlorine lifetime; and daily generation as a function of pump time and SWG percentage) this time last year for my pool and chose a Circupool T9 equivalent. Over the last year I have found It has no problem providing the...

My auxiliary pump will not turn on. No previous problems, and test operations were fine over the winter. No clicks, no sounds, no light on the board, nothing when I push the Aux1 button now. I activated service mode and pressed the Aux1 relay button; Aux 1 LED did not illuminate. Test...

I had this problem recently, to the point I was looking to replace my pump head. Turns out I had a small piece of debris on the O ring about my pump lid. I pulled the O ring, wiped it down, wiped down the mating surface, lubed and reset the O ring inside the lid lip and locked the lid down...

Different results obtain depending on inputs. If the metric is cost of lifetime chlorine production in dollars per pound, I used delivered cost of the SWG divided by lifetime chlorine output. The inputs were as follows: Hayward T9 and T15 delivered costs as found on Amazon (I believe the...

Thank you for sharing this information, I have bookmarked this.

If the value metric is rated lifetime chlorine output in dollars per pound, a Hayward T-9 at this instant is a better value than a Hayward T-15. The question, in terms of economy, for me then comes to this: for my pool, can I generate the requisite amount of chlorine with a T-9 without...

Thank you, I have bookmarked this.

I took the unit in to have it tested, it failed. I understand the variables, and believing such to be feasible for my application, I am interested in an aftermarket replacement, and would like to try a T-9 type. This one...

Folks, I think my Hayward T-15 has reached the end of its life. I would like an opinion please on the diagnostics. Stabilized readings for both polarities are below. The unit has been in service 8.5 yr. at a yearly average daily run time of 6 hrs and 55%. I've cleaned it 3 times 8 oz...

Dead end there, after some back and forth, they told me to contact StaRite.

6203 bearings were it. I ordered Nachi 6203-2NSE9C3 bearings from a CNC supplier in Wisconsin, I paid a little extra using this supplier to ensure I got what I ordered. These replaced the original NSK 6203DW bearings, which have been in service since August 2013 and appeared to still be in...

I'm going to try 10000353 aka 6203. I'll let you folks know how it turns out.

My equipment is 6.5 years old and evidence shows it is time to start replacing rubber gaskets. While doing so on the pump unit, I figured I might was well open up the motor and replace the shaft bearings for preventative maintenance. Problem is, I cannot find a whisper of intel on the bearings...

Howdy folks. I've been using and appreciating this site for some time, what a great resource. I put my pool in in 2013 and actually enjoy maintaining it. I've learned a fair amount, and have much to learn. I like to repair things, rather than replace things, and my first inclination is to...
