  I just bought and installed a new Pentair Whisperflo 2HP pump and a
  Pentair Triton II TR-100 sand filter. I connected all of the
  plumbing and electrical and turned on the pump. Everything runs good
  and then after a few minutes the pump turns off, then a couple
  minutes later back on, then a few later back off. Keeps repeating
  this.
  My question is, is this how this pump is supposed to operate??? I
  am a new pool owner and I guess I just assumed that if the power was
  on to the pump that it would run non-stop till you turn it off.
  Thanks!
  To answer your question no this is not how they operate and it sounds as if
  there is a problem with the motor. Are you running it on 120V or 220V? The
  thermal protection is what cycles the motor so for some reson it is overheating.
  
  To really dig into the issue that is WAY TO MUCH PUMP for that filter. A
  TR100 is a 3.14 square foot filter and is designed to be used with a 1hp pump or
  maybe 1.5 hp if you have long pipe runs and by long I mean 100 feet. I am not
  even going to ask what the pressure guage reads. Also unless you have at
  least two inch pipe the back pressure renders the 2hp pump useless anyway and
  you
  are spanding money for electricty that you do not need to.
  Take it back and get a 1hp and ask the dealer who sold you that combination
  to do his math.

  Thanks for responding Ken,
  Actually you are referring to the Pentair Triton II
  TR-60 at 3.14 sq. ft. The TR-100 is 4.91 sq. ft. and
  is supposed to handle 47,040 gallons every 8 hours. I
  think the 2hp Whisperflo is rated to pump around
  50,000 gallons every 8 hours. Granted I don’t know a
  lot, but that sounds right to me. Let me know if that
  sounds better with it being 4.91 sq. ft.
  As far as the pump over heating, I messed up and wired
  it for 110 instead of 220. It is good to go now.

  Your right! The TR 60 was what I was thinking about at 3.14 sq ft but even
  at 4.91 sq ft the 2 hp is still a bit much unless as I said before you have
  
  long pipe runs or other restrictions. A 1.5 hp would be a better match for two
  reasons, you are still pushing too much water for the filter and sand is
  already the worst filter of all of the types and you are spending money for
  electricity that you may not need to. I still feel the 1.5 hp would be a
  better
  match. What is the pressure guage reading?

  My brain is going soft! Kevin you need to look at flow rates of the
  components. A 4.91 is rated at 98 GPM while a 2hp pump is rated at over 120
  GPM. The
  industry standard is to use 40 feet of head to measure resistance but eash
  system differs somewhat. There is a formula for measuring head and if I can
  find it I will pass it along. Your dealer should know it as well.

  The pressure gauge of the filter is reading 10 psi. I’ve tried to
  research and find what a good pressure is but have found nothing.
  Just found that is initial psi increases above 15 psi then it is
  probably time to backwash the filter.
  I checked with the pool guy again and he said that I need the 2HP is
  good for my pool because I also have long piping to both of my
  skimmers because my pool equipment is actually outside of the pool
  area. Probably about 60 feet for one skimmer and 80 feet for the
  other.
