I'm building a partial above-ground pool and currently researching pumps. I'm looking for the difference between above-ground and in-ground pumps.
My water level is going to be above the pump, like an above-ground pool, so self-priming is not a concern.
The pool is plumbed like an in-ground, with 2" sched 40 pipe.
I have 220V available.
Above-ground pumps seem to be significantly less expensive for similar specs (e.g. Pentair OptiFlow)
Is there a reason for the price difference? Quality/reliability? Efficiency (although head curves appear similar)? Self-priming feature? Are there significant advantages with an in-ground pump that are not available on an above-ground pump.
To get a 2-speed above-ground pump, it seems that the market only provides 110V with 1.5" plumbing. Are there any 2-speed above-ground pumps out there that take 2" plumbing? Does 220V provide any significant advantages over 110V?
(Am I correct in thinking that the 220/110V pumps can switch speed by automated switching at the power supply, whereas the 110V-only pumps have to be manually switched?)
Finally, I'm looking at 16-17,000 gallons, with a roof-top (single story) solar heater. Do I need to go to 1.5HP for the heater, or will 1HP suffice?
I know, that's a lot of questions. Thanks for any help.
