Looking to completely replace Hayward Sp2610x15 serial 640b31 older model with the same thing. I see there is a single and double not sure what the difference is and if i would need to change the plumbing for double model
There are single speed and dual speed options. The plumbing is the same on both versions. The dual speed version is more energy efficient because it offers a low speed for water circulation.
The single speed is model number SP2610X15. The dual speed is model number SP2610X152S.
