Wiring diagram for pentair intelliflo pool pump

SOURCE: Will Pentair Intelliflo pump save me enough money to justify cost

Here are a couple of thoughts. If you install an intelliflo pump and run it for the same amount of time and at the same rpm as your current pump, you will still have a savings. If you drop the rpms by 1k, you will have an exponential savings. Go to the pentair website and use the program to estimate your actual savings. You can still run the heater at a reduced flow setting but there is a limit, you have to check with the heater manufacturer to see what the minimum is.

If you are running a conventional pump 24/7 you are using a ton of energy. You should be able to run the pump for 8 hours a day and achieve the same results. For instance, running the pump from 4am to noon should give you a good window to maintain the heat and not run it all the time. It also depends on if you have a cover on your pool when it's not in use. If you don't, you will lose significant heat when it's not running, however, running it early morning should give it a chance to heat back up before you want to use it again. You will have to experiment with timer settings, etc..

I really do think the intelliflo pump is a great pump. The rare earth magnet design allows it to be way more efficient than the conventional pump. It is so much more efficient that when it's running, you can hold your hand on the motor and it is just warm. Your pump motor probably runs very hot, heat is a by product of inefficiency. I hope this helps.

Your pipe could be clogged or you may have a clog in the impeller. Check the pump basket and if it is cracked then it is probally in the impeller and you may be able to reach it with a screwdriver and needlenose. If you have a crack in the skimmer basket it could be in the line and you can check this by putting a kitchen sponge in the skimmer and if it comes out in the pump the line is clear. If it is clogged you may be able to clear it with a flush bag you can get at any hardware store. If that dosn't do it you will need to get a pro. Good luck.

It sounds to me that your diffuser oring needs to be replaced. This is a common problem with that pump. The oring stretches out or breaks and this will keep the pump from creating a vaccum. This is easy to check. Shut the power off to the pump. Remove 6 bolts holding the seal plate together (do not remove the bolts that mount the motor to the pump). Their will be 2 bolts at top and bottom on each side of the seal plate that have no nuts and two bolts in the middle on each side of the seal plate that have nuts. Grab the motor and pull it away from the pump. You will see a cone on the front of the assembly. Check the oring and make sure it fits snug around the cone. If not, replace the oring. This is most likely what is wrong with your pump.

My friend, my experience with the two speed pump in low speed is less than spectacular. There is so little filter action with the lower speed as to render the process useless. If you are trying to save $, better to run the pump a little longer then turn it off. My experience is in a commercial application. I run three such pumps in that system ... the additional expense of the two speed motors was a waste of capitol. In addition, as a commercial facility, we could not meet the required water turn over rate in our pools. Of course yours is a smaller body of water and you are probably not in a commercial facility. We get a LOT of cleaning (through filtration) at night, after the customers go home.

I suppose you could run your system with a intelematic switch ... I have not seen a 'three way' switch in this line ... having said that ... to my way of thinking ... you would wire directly through the selector switch on the back of the motor to each of two intelematic's; one on the high side and the other on the low side. I would allow at least 30 minutes between the two cycles to prevent impeller damage.
