Upgrade recommendations for replacing 14" Intex sand filter combo?

[PoolDoc]

You have to look at the flow/head tables. 1/2 HP vs 1.5 HP doesn't necessarily mean ANYTHING, because of all the games they play with horsepower ratings.

One of the things I've dreamed about, is setting up a pair 'Consumer Reports' type test pools, to test various pumps, valves and filters and then publishing the results. Doing so would provide objective data about that equipment that is not currently available.

Well, one thing is for sure - I now know more than I thought I wanted to about pool filter systems. I can't find much (in some cases - any) flow/head info on AGP pool pumps. I emailed Hayward and asked for that information specifically about the 1 hp 2 speed PowerFlo Matrix. We'll see where that leads.

At this point, I'm planning on the S210T Pro Series filter and the SP15922S PowerFlo Matrix pump. If I was sure I could still vacuum effectively (with a manual vacum), I'd strongly consider the SP1750 1/2 hp pump. We are leaving for a few days of vacation this month and I'm going to wait till we get back to order.

I think the system above will clean my pool in about half the time it takes my current system. If I throttle the pump so there's no sand washed out on high, then only use high for backwash and vacuum, this system ought to be a good one. My 14" filter has about 1.06 sq.ft of filter area, the S201T has more than double that. I think I'll be running about the same GPM - if you believe Intex propaganda. I know the Intex system I have blows stuff through the sand.

Am I kidding my self?

Power-Flow II flow / head ratings, including SP1750



Also from https://www.hayward-pool.com/shop/en...ii-a-pppow2--1


BTW, the KW rating in the first image is nominal, not actual. I can't find actual amps at load for this pump ANYWHERE.

Thanks! Now if I could just get the same info - including low speed - for the PowerFlo SP15922S. I suspect the "Power-Flow II" and "PowerFlo Matrix" tables and charts all have very similar numbers, but I don't know that.

I'm worried that the SP1750, when the vacuum hose and vacuum head are attached, will not have enough flow to vacuum the pool floor. I don't know how much additional head the vacuum adds and I don't know how much flow is needed for vacuuming. I have this head

If the SP15922S on low has performance similar to the SP1750, and it won't vacuum on low, I can turn it on high, then throttle the flow as necessary.

I got a response from Hayward today. It was really helpful.

What I sent:
"Sent: 06/07/2018
I am installing a new filter system in my pool. I'm considering the
> SP15922S PowerFlo Matrix 1 HP Dual-Speed pump. Where can I find
> performance curves for high and low speeds?"

Their response:
"Thank you for your email inquiry. The only
information we have for this pump, is what we offer on our website.
WWW.HAYWARD-POOL.COM. I will speak with my leads, and see if we have
any performance curves for this model pump."

I guess they either don't know what their products will do, or they have some reason to keep me from knowing.

[PoolDoc]

They advertise performance on 'premium pumps'. They advertise price on AG pumps. It wouldn't do have data showing that 'premium' pumps didn't have any real performance advantage. I suspect they DO have some advantage, but not that much.

Regardless, you can be SURE the MARKETING department controls what the ENGINEERING department releases!

That said, I'm told many AG pumps are a pain to clean and service, but I'm not sure if that's because of the pump, or the location and piping.

I know you can't say for sure without seeing and measuring and,,, but in your opinion, Will the Hayward 1 hp 2 speed pump, paired with the 21" Hayward filter be a reasonably good system? Would the 1/2 hp pump be any better? Again, I understand you can NOT say for sure - one way or the other. But,?,?,?

It seems like it can't be too bad since Hayward sells a system that has the 1 hp pump paired with an 18" filter.

And by the way, a Hayward 1 hp 2 speed Super Pump is about twice the cost of the PowerFlo Matrix 1 hp 2 speed.

Just pulled the trigger on this pump:

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Sold by: Amazon.com Services, Inc.
$258.55
Condition: Used - Like New

Yup, it's a gamble, but it's less than half price and less than the Hayward 1hp 2 speed new, and it's from Amazon, so I "should" be able to return it if I need to.

I also ordered a Hayward S210T filter along with various fittings, valves and accessories.

I'm getting ready to have the mostest sparklingest Intex pool in the DFW area, thanks to PoolSolutions, PoolForum, and the PoolDoc.

This is what came with the SP1023 - non-G - bulkhead fitting from Amazon, in a sealed Hayward plastic bag: a bulkhead fitting, 1 backing nut, 2 rubber washers and 1 cork washer.

I'm not going to use the cork washer at all. I will use both rubber washers, one inside and the other outside. I don't think the outside will be necessary for sealing, but it will provide a cushion between the vinyl liner and the hard edge of the backing nut. I don't think there would be any advantage to a sandwich washer for me. If one had 2 layers, where the vinyl liner was supported by a metal or fiberglass shell, the sandwich washer might be useful in ensuring water couldn't get BETWEEN the layers.

From a different thread:

The WhisperFlo is almost certainly too big . . . unless you get at least a 24" sand filter.

I expect to throttle the pump and/or run the pump on low. I have a valve for that purpose ordered. The owners manual has flow/head curves that show the pump moves 45 GPM max and about 15 GPM @ 20' on low. High speed moves 95 GPM max, 85 GPM @ 30' and about 22 GPM (close to what I need) 80'.

Look at the differencee between these bulkhead fittings:

Hayward SP1023 bulkhead fitting
Hayward SP1023G bulkhead fitting

Please let me know which bulkhead you use, and it works.

The difference between SP1023 and SP1023G is the inclusion of a "sandwich washer" in addition to the standard washer with the -G. I think I'll be okay with the non-G fitting. If they leak, I'll order the sandwich washers (assuming I can) or return the non-G fittings and order G type.
