First, thanks for all that reads this post...
I have a commercial pool (13 vacation rental units use it) in FL, used 24/7 year round. It has a drip edge, about 40K gallons, surge tank, 2.5 inch pipe to the pump (very old). The pump is a Hayward SP4020X25NS 2.5 HP Northstar pump about 8-9 years old. I just heard a high pitch screeching noise, not sure if it is the motor or pump. My initial guess is the motor. I just got back form a local distributor I use. New Tristar 2 HP unit $768, 3 HP $967, online prices about 25% less counting shipping and no tax. Motor only $378 local and about $300 online.
Is it time to replace the whole thing? Impeller? Motor? Impeller and Motor? Another type or MFG? As anyone in business, I want to keep the cost low. If a complete replacement, should it be 2 or 3 HP? Seasoned veterans please chime in
I am not overly concerned about utility bills, but it can't be overlooked. Overall maximum quality is a bigger priority.
