Filter Size vs Pump Size

[CarlD]

Thanks Ben. I wasn't questioning your judgement, just looking to see what I was missing in Hayward's published specs. At 34 GPM it's clear the C900 is 'way too small for the 1.5 superpump. Do you think a 300# sand filter would also be a good alternative to the C900? Finding parts to downsize a pump's impeller is, as you know, a PIA.

Actually, both the impeller and the seal are available on Amazon. The real problem is, can it be installed?

Anyhow, this seal:

Hayward SPX1600Z2 Seal Assembly

and one of these three impellers:

Hayward SPX2600C Impeller
Hayward SPX2605C Impeller
Hayward SPX2607C Impeller

But I'd need to see photos of the pool and piping to be sure. Also, the exact Super Pump model number needs to be confirmed. A 1.5HP pump is either a SP2610x15 *or* a SP2615x20.

If the choice is to stay with the existing pump, a matching filter would be a SwimClear C2030, rated at 84GPM commercial.

Just for ball-park: The c2030 runs about $535 on Amazon Prime. But plumbing it in to replace the C900 should be a piece of cake with PVC fittings--basically a drop-in job.

Be careful to purchase from Amazon, rather than a 3rd party if possible. The link above *should* go to Amazon as a seller, but didn't when I checked a couple of hours after posting it.

Same link I found! Amazon Prime is, we find, well worth the $99/year it costs. Amazon's 3rd party shippers aren't nearly as reliable or honest in their shipping times as Amazon and especially Prime. I've had stuff listed "in stock" from 3rd parties all of a sudden have to wait a month to be shipped from China! When it's an iPad screen, for example, that's a problem. But Prime? Works like a charm!

I use Prime all the time. I more than make up the $99 in not having shipping fees. For us, it's a great deal. Plus, I'm a little impatient; when I order something, I want it to arrive yesterday!

Than you for all the help. I bought the pump I have now from Amazon. I had to replace the old pump. To bad I picked one that is too big. Oh well. I guess I'll save up and buy the c2030.
