Hi! I recently purchased a home that came with an in-ground spa:
1500 Gallons
A small two feet tall 30 GPM Waterfall (that is currently being blasted at over 100GPM)
Jets and Blower
Hayward Heater
24" Hayward Sand Filter (filter is cracked and needs to be replaced)
2HP Motor (way, way overkill)
Diversion Valve for Waterfall or Jets (or Combination)
System about 30' from pool
Here is my issue, my wife really wants to run the waterfall during the afternoon for aesthetic purposes. However, I dont want to pay to run a 2 HP pump for something a 1/2 HP could handle.
I am in the power industry and know just enough about pumps to know I can screw things up, so I wanted to get some pros advise on the below idea:
Reroute the 2HP pump to operate the jets only
Install a small pump/sand filter that is routed to the waterfall only (will run every day to turn/filter water and give us a waterfall)
Questions:
Can I use a single 2" supply line to run two mismatched pumps?
Also, all of the filters that are the size I want have gravity fed pumps. My system is installed next to a wing wall so getting water gravity fed to the inlet would not be an issue.
But can I run a 2HP pump with a small gravity fed pump on the same inlet line?
What happens when someone accidentally turns both pumps on?
Assuming we make it to this question, is there any issue using an "above ground" filter/pump in an inground pool (keeping in mind that I can gravity feed the pump)
Thanks in advance!
