New Pool Pump Suggestions

[Mark]

If the impeller is sized for a 1HP uprated motor and they used a 1.5 HP uprated motor, then that should be fine. However, if they somehow mislabled the pump, then it could be a 1.5 HP uprated pump. I was just suggesting that one way to tell is to check the impeller part #. It shouldn't too be hard to take apart. Clearly there is a mismatch somewhere and it should be looked into.

I think that the motor that goes to that pump should be a 3/4 H.P full rated with a service factor of 1.33 or a max rated 1.0 H.P with a service factor of 1.0 for a total H.P of 1.0.

It looks like the motor that is on the pump might be a full rated 1.5 H.P with a service factor of 1.3, which would be a total of 1.95 total H.P, which would be almost twice what it should be putting the motor outside the best efficiency range.

Thanks to both of you. I have contacted the vendor and it will be going back. I have a while before the water gets too green....

Either a mislabeled motor and it truly is 1 HP (although it is significantly larger than my single speed 1HP) or it is 1.5 as I suspect and was mistakenly put on this 1 HP rated pump. Even the box label has the correct sp pump number and a big 1HP next to it.

Another possibility is that it is a mislabeled pump and does have the appropriate 1.5 hp motor for the pump and as I have learned from you guys if that is the case I also have a 1.5 hp rated impeller and would loose efficiency.

Figures to happen to a DIYfer. Have you guys seen this mistake before? Is it a rare occurrence?

Thanks again fellows, I am learning a lot, I'll let you know how it turns out.

Thanks for the update. I'm glad that this will be taken care of with no problem.

It is not common, but mistakes happen. Hayward is a good company and generally tries to make things right when something does not go exactly as planned.

Pump is going back tomorrow. When the time came I had quite the time convincing the vendor that it was incorrect. They even called Hayward and got the wrong info, but they were probably asking the wrong questions. It seems there are others in their inventory built like this as the vendor said they opened a box and found the same thing. They have since ordered one directly from Hayward and will pick up what I have tomorrow. I am happy with the service from both Hayward and the vendor...Things happen, but if resolved correctly it can only help your reputation. Interesting Huh?

I emptied the filter today, and took off the top. Looked filthy inside, I have most of the sand out. I took the handle assembly off and took it apart. I need a new gasket but there doesn't seem to be much else regarding the handle that needs changing. Will add a new gauge. I haven't gotten all the sand out yet but am curious how everything looks.

Thanks for holding my hand guys. Can't tell you how much I appreciate this.

Emptied the sand and unscrewed the laterals. They are not broken, but not sure how clean they should be. The handle assembly that goes inside the filter just sits inside the tank and joins the pvc tube that has the laterals. Is it supposed to be like that? Is it supposed to be loose without a permanent connection?

[quantumchromodynamics]

The valve assembly just slides onto the PVC pipe. There is an O-ring inside the valve that makes the seal. Make sure that the O-ring is in good condition and lubricated with a silicone based lubricant. The valve is held in place by the clamp that attaches the valve to the main filter tank.

Pump is in and working great. The sand that I removed looks like it wasn't what was recommended. The prior owner used something that looked like beach sand. I had yellow algae around the sides and in the pool. Swept and chlorinated and ran the pump for 24 hours and the water is clear with small insignificant amounts of dirt returning. It is super quiet also especially on low speed.

Thanks very much quantum for guiding me through all of this. It was very much appreciated.

Thanks for the update. I'm glad that things are working well.

I'm not sure why you are getting small amounts of dirt returning, there must be a small gap somewhere. If it's not too much, you should be able to ignore it, but it would be the kind of thing that would bug me.

How much are you running the pump on each speed per day?

[mstng]

I had it on high speed for 24 hours and at the 12 hour mark it was looking good. This was with a green dirty filthy pool. I just swept the small amout of dirt that made it through the returns down to the drain and put in on low speed. I'll see how it looks tomorrow. Hopefully it won't be a problem once I get it cleaned up. There was alot of dirt to start with. It's amazing that I can't even hear it on low speed.

thanks again

Yes, that's one of the benefits. What kind of flow do you get on low speed? Do you get good action in the skimmer? What is the filter pressure on high and low speed?

Skimmer action looks good. The pressure on high speed is around 10 and the pressure on low barely registers. Is that normal? I haven't seen much residue from the returns anymore. I am happy so far thanks to you.
