I currently have an old Hayward Super II Pump 1.5 hp. The filter is a 30" hayward sand filter with 2X2" piping for a Hayward pool VAC XL vacuum and skimmer. It is a ~16,000 gal pool. The piping runs are about 80' from the pumping station to the pool. The pump currently runs fine I am just trying to reduce energy consumption as my average energy rate is $0.21 /kWhr. It currently runs 4 hours a day and I don't have algae problems. I have been going in circles trying to figure out which way to go between just replacing the motor or replacing the wet end, too. I am also torn between two-speed and VS. I have no brand preference, the hayward parts were all installed when I bought the house. I do not currently have any automation but I am not against adding it later.
My thought on replacing everything - I have owned the house for 4 years and have only replaced the o-ring on the cover to the pump basket. I don't know how long it has been in service or how long it will last. Would it be cheaper/easier to just replace everything at once instead of pigeon holing myself into certain replacement motors for a wet end that may only have a few more years in it?
Anyways, any sort of help would be greatly appreciated as my head is currently spinning trying to learn and decipher everything on my own.
