Can I upgrade from the Hayward EC-65 to the EC-75 using the same pump?

[bobjersey]

I am considering upgrading from the EC-65 to the EC-75 because my pool is 20'x40', 10 feet deep and roughly 40,000 gallons and I see the EC-75 can filter almost this entire amount in 8 hours.

I have been using an EC-65 for many years but it broke last season. Can I do this while still using the pump and base from my old EC-65 system? I do not know what the horsepower of my pump is - the identifying labels have been worn off by the elements. I am using the "System III" base.

Thanks for any quick help since I need to buy this pump (either the EC-75 or a new EC-65) asap!

Welcome to the forum!

You sure can, the tanks are the same, the only difference is the length of the 'fingers' :cool:

You may have to disassemble and rotate the top to match up with the return plumbing, but otherwise, it's gonna run and match up the same as your EC 65 :)

Good luck with the upgrade.
