Appropriate replacement of my 18 year old Jandy Stealth 1.5HP single speed pump

[Siglumous]

Hi all. I'm thinking ahead to the eventual (soon?) replacement of my 18 year old Jandy Stealth 1.5HP single speed pump. I've read that there's a potential savings on electricity moving to a VSP. And given the age, I may just want to jump in and replace it sooner rather than waiting for it to fail at an inopportune time. So, I've started looking and wondering how I should size the replacement.

As noted in my signature, I have a 13,500 gallon lap pool, with a cover that is used often (open on nice days, closed every night). I've been running the pump 8 hours/day. I plan to move to a SWCG next season, so likely will be running the pump longer.

I have two scenarios:
1) I have an opportunity to pick up a one-year old Jandy 2.7HP VSP. I'm not sure how the sizing works. I'm assuming right now my pump operates at the single speed and 1.5HP? If I get the 2.7HP pump, and it cranks itself down does it go to 1.5HP...and lower? Would I ever need the "excess" HP and would it be stupid to get this if the excess capticity is never used?
2)Just get a new Jandy VSP with "the right" size. Since I'm moving from a single speed, what is the right sized VSP for my pool?

Thanks.

1) Even if you never run at full speed, having such a large pump has it's advantages. Lower RPM for a given flow rate means less noise. Larger impeller means less likely to get clogged. No real downside to going larger than you need.

2) see #1

Thank you for the reply. Good to know there is no downside.

Sig,

My theory is that you can never go too big when buying a VS pump or a larger filter.

Go big or go home!!

Thanks,

I am in a similar boat. Where are you getting the VSP Jandy as I am looking for a similar one and if there is something I can buy as well..

The jandy epump fits the stealth unions, so no replumbing is needed. It’s should be compatible with your pda as long as it’s REV4 or later. If not you will need the controller.
