Gotcha. I am following up a lead on the Solar Install company for my setup. Heck, they may have done the entire pool installation.

Sorry for any confusion on starting a new thread. In my original thread I was trying to understand how the individual components worked, especially the 3-way valve with an actuator. Once I understood that, I thought discussion about the overall Solar heating system was not appropriate for...

My system has some quirks. I have updated my signature with more info about the parts in the system. I have attached a Water Flow Graphical Chart similar to the one on the website(graphics are plain though). The Jandy/Fafco 3-way valve is setup in a non-standard way. (Not my doing:)) I will have...

I don't plan on doing it. I am trying to understand & write some documentation for myself to ensure I don't make the mistake. Dana

Thank you for the the great link. After my first cursory perusal, I believe my water flow setup may not be the "typical" setup. I need to read & watch to better understand how the system is suppose to run and & how to manage it. There is one question - If you have the input to the Solar Rooftop...

I am talking about roof top solar panels through which your pump pool water through. Right now, I am trying to educate myself on the system. I am sure there will be more specific questions after I get a handle on the system. Thanks, Dana

Hello, Is there a document or link to a webpage that explains the who, what , when, where, why & how of a Solar Power Heating system? Thanks, Dana

On to the Pool cleaning part of the forums for further education. Thank you. Dana

Good to know. It looks like they did at least 1 one thin correctly on my system. My in-pool vacuum's booster pump is down stream from the main pump & filter. Looks like I can run it independently from the main pump. Thanks, Dana

Hello, When the main pump is turned off does it still allow water to flow through it? Thanks, Dana

I don't have a manual for the system. The first chart I made. I was trying to understand the overall system and all the parts, manufacturers, etc. The 2 chart is just the water flow. Much simpler.

I made a simpler chart. But yes, The Jandy/Fafco valve only opens/closes Port B. Port A (to pool) & Port B (from Solar) are always open. If the handle is in the vertical position, (Pointing to Port C) the only way to get return water to the pool is through the Solar system. If the handle is...

The system is probably 20+ years old. I purchased the house with this system already installed. Up until now, I had remained "ignorant" on the system & let my pool maintenance guy handle everything. Unfortunately, he moved away & his recommended replacement has already cost me a new pump. I have...

Maybe the best way to get the decibel ratings is from crowd sourcing. There are phone apps for decibel meters.

That is good to know. It now gives me some other ideas. Still would like to have the decibel ratings though. Me thinks the manfacturers realize this would be a show stopper for some of their pumps. Thanks, Dana

After reading the suggested manual... I think I understand how a 3-way valve works. Just to double check... In a "standard" 3-way valve setup, the horizontal, (half way between ports A&C) position of the handle indicates both A&C are fully open & B is fully open. So my setup, has A & B always...

From the video of the decibel test of a variable speed pump, in order to get the low noise affect it has to be run at a low rpm rate decreasing the GPM. At a low GPM I would have to run a variable speed pump almost 24 hours per day to get the necessary water volume turnover. How often do you...

Hello, I can't find decibel ratings for any of the manufacturer's pumps. Does anyone know of a site that has collected this information? I did find a youtube video of a single variable speed pump being measured. Thanks, Dana

Hello, This Fafco valve says "Reversible" in large bold letters on it. I believe my valve is being used as a sideways laying "T". The top "T" connector is coming from the pump/filter source as an input source to the valve. The bottom "T' connector is actually always open and is going to the pool...

Hello, I have a Jandy, (JVA2440) actuator coupled with a Fafco Reversible valve. Is it viewed as a "T"? Are the two 't' ends the input and the stem the output? Or is it viewed as a circle with the choice of input/output to any one of the 3 stems? Thank you, Dana

Sounds like it should not be allowed to happen. Thank you. Dana

Hello, What affect on the pump and or filter occurs when the pump is turned on but the pipe exiting the filter is closed off? Thanks, Dana

I found another post explaining how the automatic valve actuators work. I will try those instructions to see if I can get the Solar Control Panel to set the handle in the suggested directions. Thank you, Dana

I have just a basic pool. I have attached a photo of the pool and the equipment setup. I believe the white disc is a part from one of the return's cover assembly. I believe I have 7 return ports at the bottom of the pool plus 1 drain. I spent most of yesterday understanding how the whole system...
