Screaming Hayward Northstar Pump

My 2.0hp Hayward Northstar pool pump is making that screaming noise. Since it is 17 years old and single speed, it is probably time for a pump replacement with a 2 speed or VS pump.

I am looking for recommendations on a solid replacement. My run time during the summer is nearly all day due to the pool size/location, chlorine load, and Aquarite T-15. My existing controller is an old Hayward 2100 system that has a limited understanding of 2-speed pumps.

Any recommendations from the collective intelligence of tfp. I would like to spend the right amount for a good solution and remain somewhat budget friendly.

Thanks for any recommendations.
 
I have contacted a local service company that I use for simple repairs but I think their responses so far have been mostly self-serving with estimates of $4k for VS because "my controller doesn't do VS". I cannot physically do the repair myself anymore, but any recommendations for a local contractor in dfw would also be appreciated.
 
djw,

While I love VS pumps, in your case a 2-speed pump may be all you need... I just glanced at the 2100 manual and it appears to have the 2-speed option.

It will reduce your electrical cost by about 75%...

I personally like Pentair pumps, but then I am a little biased as that is what I have.

Thanks,

Jim R.

this is a good option, and you can examine all makes and models since no automation
 
Since I am a newbie at VS pumps, from what I am reading many of them can be controlled by their own on-pump keypads. I could leave the pump on from the Hayward 2100 side and do all the fancy programming on the pump and get the big savings VS pumps are supposed to be able to provide. Am I missing something?

I don't really want to scrap a working controller system but I would like the savings of the VS. It looks like I can get into one, example Hayward TriStar VS 2.7 for $1200+install.

I was looking at my smartmetertexas.com account with the pump being off. Over the course of the year my pump probably consumes around $1800 if I were paying .10/kwh. I run the pump nearly all the time in the summer to keep up with the chlorine demand a 40K pool has on an T-15 salt cell.

Am I missing something on my thinking? Does the T-15 flow sensor deal with the low power VS settings ok?

I would not mind giving my local pool support guy the business, but I doubt I would do so at 100% mark-up.

W a 40K gal pool, and W SWG requirements, you need to do the math on how long (and what RPM's) to run any pump to Clorinate your pool? If you're spending $1800 / yr w 3450rpm single speed, in 5 yrs you've spent $9,000 on electricity.

So, changing out an 18 yr old pump and controller, over the long haul, would make a lot of sense from many perspectives. I would determine what it would take to install a 3HP Intelliflo to run your SWC at a RPM that will keep your pool sanitized at peak season...from there you can work backwards, then do the math on capital outlays and diff variable costs on power. I would rather pay more up front, then have a lot less variable costs, esp when you have no real control on Khw's per se. Make sense? I'm not a SWG pool owner, so I'm sure someone here can help you w that application and pump requirements.

Good luck
 
It would probably be cheaper to scrap the t15 if it's a few yrs old and go to a 60k cell and a 2 speed pump. You would run it less and on low speed it would satisfy the flow switch. You may cut your run time in half and at a lower speed for about the same money ot less than just a vs pump

Based on the price of the IC60 i might be better off with two T-15s running in parallel. 80k gal output and at half time on a pump. Some built in redundancy there. I’ve been seriously thinking about how to do this for a while. When one cell goes out, and they do in time, there’s a plan b - just double the pump run time until the cell is replaced.
 
there are other brands talked about here much cheaper than an IC60. all depends how you want to go about it. you could keep running the T15 til it dies and just add in another cell in addition to it. I was just thinking the fact you dont have newer style automation setup you arent tied to any particular brand at this point. personally I would have no problem trying out a cell from the other less knowns, I have read decent reviews on them here and price point is great
