SOURCE: Pump works in spa mode, but doesn't work in pool mode. Why?

We need more info. Which control system is it? Suntouch, easytouch, intellitouch.......? It sounds like a programming problem in the controller.

SOURCE: Pool pump starts & stops on its own outside of programmed run

There are several potential problems:

  • freeze protection circuit causing pump to start - could be a bad outside air temperature sensor.
  • It is possible the new relay is bad.
  • There could be a short in the control wires to the relay
  • old programming shadow stuck in memory (not likely since you changed the boards)
Yes, the starting and stopping can harm your pump.

SOURCE: I have new pentair 1 hp pump that was intalled by

to open the basket the pump needs to be off. all drains and the skimmer needs to be shut. otherwise all the water from the pool will leak out... now when you have done all of that. there should be a ring around the lid you take a hold of that and twist. it can be alittle stiff at first.. When you get that ring off the lid will pop off. now water will come out of it becuase it's just what's in the pump and in the line. once the water is out you can take the basket out and clean it. Now very important. when you put the lid and the locking ring back on open the skimmer and the drains to get water back into the pump. If the pump is not filling up go ahead and automatically put water in there until it's full. once the pump is full you can turn back on the pump and everything should work fine. if you have any other questions please let me know.

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.

Hi, I have just installed a new Nocchi / Pentair 1 hp pump, 230v the problem is it is overheating after 7 mins & the thermal switch activates. after this it cycles on/off every 50 seconds, the pipework...

Sounds like you have done eveythig correctly - since the pump is new I suggest you contact the seller of the pump, or the local service agent as it could be a thermal overload problem.
