Replacing a 2-speed pump

My original 2-speed pump locked up so I need to replace it. I've been told 2-speed pumps are no longer made, so I'm left with a variable speed pump ($$$) or a single speed. My current pump is 2 HP, which I'm also told isn't made anymore either. I have one quote for a 1.65 HP pump and another for a 1 HP pump. The guy who quoted the 1 HP pump said it would be sufficient but I'm concerned since the existing pump is 2 HP. My pool is inground, salt, 12k gallons, electric heat. It originally had a pressure side cleaner but I've switched to battery-powered cleaning robots so nothing runs off the pump. Thoughts?

Get a variable speed 1hp

What size is your pipes?  1.5inch is usually recommended to stay at the 1.65hp range.

2inch+ can go larger pump hp.  

With a variable speed, you dont run full speed for long during normal operations.

Are you at all capable of DIY?  a variable speed pump motor retrofit is significantly cheaper and several youtube videos show how to do it.

I believe pump inlet and outlet pipes are 1.5"

I could probably DIY the replacement, I just don't have the time or interest in doing it. 

What's the benefit of a short full speed run with a variable speed pump?

You can still get 2 speed pumps.

Just buy a 1 hp single speed. That’s all u need for that size pool. If u want to save money put everything on a timer
