I have a Hayward NorthStar that I am looking to replace. The only one's I see all have a threaded union connection. Do you still carry the one with the Quad lock?
Reply
Unfortunately Hayward discontinued the Quad Lock design on the NorthStar pump models in 2007. The housing on the newer pumps is a threaded design and re-plumbing would be necessary.

I need to replace the motor on a Hayward Northstar Pump SP4015X20NS. Could you recommend the correct 2HP motor?

I have a Northstar Hayward SP4015X20NS pump and motor. The pump is leaking water from the back and underneath the pump. I tried to find a new one but all sites say it is obsolete. What is a direct replacement I can use? PS My motor is fine, can I just buy the pump>
Reply
Hi Jim, There is not a direct replace for the Northstar Pool Pump 2 HP that will match up with the plumbing but performance wise the Hayward TriStar 1-1/2 HP, Energy Efficient, Full Rated Pump will be a suitable replacement. You will have to re-plumb this pump into your set up. You can purchase replacement parts, there is a Northstar 1998-2007 and a Northstar 2008-Current version.

What replaces the SP4015X20NS Hayward Northstar pump since this is no longer available?
Reply
Hello, Jacky, The closest replacement for your SP4015x20ns Northstar Pool Pump 2 HP would be the SP3215X20 Hayward TriStar 2 HP, Max Rated Pump or SP3215EE Hayward TriStar 1-1/2 HP, Energy Efficient, Full Rated Pump. You will have to do some replumbing but they will be the closest in performance to the Northstar.

Hello! The motor on my Northstar SP4015X20NS died and I would like to replace just the motor with either a 2-speed or variable speed motor. Is there a variable speed motor that will work or do you only recommend the Hayward SPX1615Z2MNS 2-speed, 2HP unrated motor you have listed on the parts page. Thanks!
Reply
Part number ECM27CU is a great variable speed motor that will fit your Northstar. Is your Northstar before 2007 or after 2007 model, that is going to matter for the shaft seal because the two difference Northstars have two difference shaft seals. You will want to replace the shaft seal when you do the motor installation.

(1 out of 5 stars) Pump not workingon delivery
Reviewed By: Yngve L. from Plano, TX ()
The pump was not working on delivery. Northstar does not seem to be interested to help. Northstar has not answered the claim after one week. "Inyo Pool Products" needs to be more active on following up claims. A customer should not be left between the seller and the manufacturer.

(5 out of 5 stars) Hayward Northstar Replacement
Reviewed By: Marcel G. from Lafayette, LA ()
Pros: Great pump
Cons: Different fittings
The pump was great; however, evidently Hayward put different fittings on the pump that did not match the ones I had. I had to replumb the fittings on my system. The older fittings seemed to be much better than the new ones. They were easier to remove and install.

(5 out of 5 stars) Great Product
Reviewed By: Phil K. from Newnan, GA ()
I had one of these for ten years and it only died due to our letting the water run low and the pump continued to run all night. This pump is very reliable.

Ordered pump on Tues and received it on the following Monday. I'm in Texas, pump came from Florida. INYOpools employees were knowledgable, helpful, and curtious. Packaged great and brand spankin new. Not one suggestion to improve the service because it was great.

(5 out of 5 stars) Hayward Northstar 2HP
Reviewed By: John G. from Frisco, TX ()
Pros: Very Quiet, better pressure
Cons: None encountered so far
Replaced 6 year old northstar (2hp), this one is so much quieter, not sure if the original was just bad or bearings going bad over the years - much quieter, better pressure. Price on INYO was more than4 $300 cheaper than any pool place around selling it!

(5 out of 5 stars) Awesome pool pump
Reviewed By: Bill in Texas from Frisco, TX ()
Pros: Cost and quality
Cons: None to speak of
Ordered new pump unit from inyopool and could not be happier. Shipped to me in 2 day's and the price was 20-25% less than the next competitor. The cost for replacement is far better than a rebuild. Thanks Inyopool for the great price and service. "you guy's rock"
