Replacing Pool Pump Help

[9452772]

I have a 1HP single speed Hayward pool pump that I am guessing is 15 years old. It has started making noise in the pump area and not holding pressure like it used to. I have check for obstructions and leaks and found none. My pool is between 10,000 - 12,000 gallons with no water features and only two jets on the side and one skimmer. I am thinking it is time to replace and thinking of going variable speed. Between Hayward, Jandy and Pentair there are a ton of options. Does anyone have a recommendation on pool pump? Also, what would be the maximum HP I should go with? If I was buying single speed I would stay with 1HP but not sure with variable. FYI, I will do the install myself.

Also, the pump is about 50 feet from the pool and at the same level. I have pool heating solar panels on the roof of the pool house and I have been happy with the results of the current pump over the years.

I would just go back to single speed 1hp with only 2 returns and 1 skimmer
The cost savings on electricity usage would be marginal and most variable speeds start up and cycle to peak HP which I don’t see improving your circulation.

Just replaced mine last year with a Pentair Superflo VS, love it, can't even hear it.

I wish I was closer. I’m in the pool repair business. I would replace the motor, shaft seals, diffuser and impeller. You’d basically have a new pump minus the pump housing for a lot less than a new pump.
I’ve converted a bunch of variable speed pumps to single speed when the control boards go out. They’re super expensive to repair

Listen to Sparkles! He knows.

Pentair is good

spot on .... did this exact fix/repair with my Pentair pump and it's running like new w/out the extra costs.

Me, too with Hayward. I'm a tightwad and thought I could save a few bucks. Probably saved hundreds with just a little elbow grease. You don't need any previous experience.

Same

I did the same thing too...Its not that hard to do.

Just put in pentair 2.5 hp variable, replacing my northstar hayward 2.5hp. Can run 2850 rpms and get the same performance at the northstar at 3500 rpms. Did not run the break even cost, but our KWH rates are insane.

Our 2hp Pentair only lasted 2 years. Our pool is an 24' Above Ground. It came with a Pentair pump & sand filter "skid unit". When the pump failed, I looked to no avail for a "like for like" replacement pump. No 2hp was available. I found a 2hp Hayward on Doheny's site. I was really surprised to find that the Pentair hoses would not buckle up to the Hayward pump. I had to buy a bunch of fittings and another hose with a Pentair fitting on one end and a regular pipe thread on the other end (costly), but finally was able to make it work. I guess I said all this to say - If I had it to do again, I don't think I'd go with Pentair.

They all have different fitting sizes and it can be a real PITA at times

This. Two returns and one skimmer doesn't justify buying a high HP pump. We are a builder and only use 3HP Pentair Intelliflo Variable Speed Pumps and Jandy 2.7HP variable Speed Epumps on new builds but we run two skimmers on every pool with 2.5" sections and 2" returns.

My pump motor was going bad. Ordered a new one, it came in last week. Went to pull the old motor, turned 3 bolts and you guessed it, the head snapped off the fourth bolt.

Went ahead and ordered a whole new wet end with all the guts.
