Hey all, I was servicing my old 1.5HP Pentair Ultra Flow pump this morning and the impeller broke. I also noticed the ground on the motor needed some parts to secure it better and then the gasket kit. I'm looking at $100 to $150 in money and I don't know how many hours of time to get this thing running again and then I still have a Watt guzzling pump running. I am now thinking about a VS pump and then see that the big recommendation is a 2 speed pump. I'd like a recommendation. I'm also confused about TDH. The VS pump data sheets show flow on the TDH vs GPM at certain RPM but it seems like at the lower speeds you would have zero flow if your TDH is over 20 or 30. The heater and sand filter require 55gpm and I have no idea what my TDH is but I'm guessing between 50-60. kWh cost is 0.10633 cents and I'm running the pump about 10 hr a day currently.
What size pump should I get?
Any Pump recommendations? I'm considering one of the Haywards or Pentairs (either Whisper or a VS)
Is the realized cost savings really that noticable?
I'm pretty upset about this whole ordeal since the pool is looking great and I've been SLAMing it for a while and now I'm going to be stagnate until this is fixed. Uggh!!! It's never ending.
