We built a pool a few years ago - the one feature my wife wanted was a slide... She uses it almost every time we use the pool. She is a kid at heart!

Hi-
We are getting our vinyl liner replaced, and the water in the pool has been drained. The pool had green water prior to draining, so I am wondering how to clean/drain/what to do with the pump/piping/filter to get that gross water out. I imagine with the new liner and clean refilled water I will send a bunch of that gross water back in once the pump is back on- is there a way to avoid that by cleaning/draining it now? Or is that just a part of the process and I’ll SLAM it to fix it?

Buy the parts, build your own pump and save $600.00.

JamesW · Mar 24, 2025

Maybe everyone should just buy the parts instead of the whole pump since it is cheaper.

Ugh. Well, that’s going to screw up all the chemistry.

It's not so bad...

Your pH and TA will likely be fine. Just get your pH back in range 7.0 to 8.0.

CH is an easy adjustment if low. Same with CYA, and FC.

Start with CYA and FC, then worry about pH an CH (min 250 to protect the plaster).

Easy living...

Same motor.

Thank you! That's interesting... how are superflo and whisperflo rated at different HPs if they have the same motor powering them? Sorry if this is a naive question.

Is there a barcode sticker with a P/N and date?

I tried to find it but it looks like that sticker's been taken off. I found this serial number locator, but on my pump... there's nothing there.

Hi, my new pool was finished and filled about 4 days ago. It has an aqua blue mini pebble surface. It was acid washed by the installer prior to filling. Everything I’ve read talks a lot about plaster dust in a new pool. I’ve been very religious about brushing twice a day and have been testing water twice a day as well making smaller adjustments as I go. My last house with a pool, the pool was many years old by the time we got there so no experience starting a new pool. I have not seen anything that resembles a dust like substance so I’m wondering if because it was acid washed prior to filling, does that mean I should not expect plaster dust or maybe its still coming?? Or maybe I have it and can’t tell? I’m assuming it would be pretty obvious if I had plaster dust.

The pH has been hard to keep down, going through a lot of muriatic acid, but I’m thinking that’s somewhat normal based on other posts?? (2 gallons so far in 4 days)

CYA35, TA150, pH = 7.7, CH350 ~9000 gallons

I’d suggest turning off your SWG until your salt levels are back to normal. Some prologic boards can overheat and be damaged when operated with unusually high salt levels.

Recently updated a lot of the pool equipment in my new place with your guys' help - thank you! But I kept the old Calimar 1.5 HP pump and added the automation adapter to have better control using 3 relays on the intellicenter. However, always thought it would be nice to have a pentair pump to go with the intellicenter and all the other pentair equipment that I had installed. Wanted more customization other than the 3 relays could provide using Calimar. Also I was maxing out on the pump RPMs to get a flow rate of around 50GPM to get water to the solar collectors. Thought a slightly bigger pump might be ideal.

So I've been checking facebook marketplace and offerup to see if I can score on a good deal. Saw one today - whisperflo vst for a reasonable price, only in use for a couple weeks before the seller realized it wasn't meeting his needs and he needs the intelliflo instead. I get the pump and it looks pretty new, however, when I unscrewed the control panel to make my electrical connections, I saw a NIDEC drive kit. When I googled the model number (KCCA0348-P2-G31), it shows up as a superflo drive -- click here .

Now I'm wondering if this pump has been refurbished... I checked the pictures for both whisperflo and superflo and the pump housing looks like whisperflo (pictures attached) but the only thing throwing me off is the motor/drive. The metal on the outside is a gold color (like superflo, although whisperflo is similar looking) and the nidec model number (KCCA0348-P2-G31). Of course I worry if that drive is a superflo drive than it won't produce the HPs a whisperflo is supposed to. Learned by lesson to only buy things new from a reputable dealer when it comes to expensive equipment.

I'm going to call pentair tomorrow and ask. The seller says he hasn't touched it...

Does anyone know if a whisperflo vst can have that nidec drive?

Thank you!

Best to just replace rather than rebuild.

There is an argument to be made for this, but I think it is closer to a tossup. The Pentair pump wet ends are really good, and have lots of available parts. And, OP will have to rebuild plumbing, unless he buys another Whisperflo.

No matter what route the OP goes, a VSP WILL save significant $$ over a single speed. Enough to make the payback 1-2 years. This was an analysis I did on dual speed vs. VSP for a Hayward pump owner (single speed payback is quicker than 2 speed). Whether you get a new VSP or upgrade your pump, it will payback itself.

Either way, OP is on the right track and asking the right questions!

Is the 200 sq ft filter size high enough for my size pool, or should I upgrade to a 325 sq ft cartridge filter?

I would get the largest filter that you can afford, and that will fit on your pad.

It will come down to the amount of debris. Your backyard doesn't look too bad. I would get at least a 200. Is a 300 worth it? That is a question that can't be answered until you install one and see how often you need to clean. The larger you get the longer between cleanings.

Sand vs. Cart. is a personal preference. Both work well. Backwash with sand is likely a 10-15 minute chore every couple of weeks. And, you need a place for the water to go. With a large cartridge, you may get by with 1-2 cleanings a year, and will take about 30-60 minutes.

Did you need to increase rpms for a flow switch say on the salt system or the heater?

Not for the salt system, but any heater will reduce flow. Heaters also have a minimum flow to not damage the heater. They typically have pressure switches, but pressure switches are not a good proxy for flow. Hence, the heat can still heat with insufficient flow, but cause damage. I don't know why they don't use flow switches. This is also why you want a heater bypass as noted. You want to isolate the heater when you are not heating, to reduce RPMs on the VSP. As a note, you don't want to completely isolate the heater, 95% bypass, 5% heater will keep chlorinated water circulating through the heater. Eliminating the heater would eliminate the need to run higher RPM and the need for the bypass.

You likely will have to run about 1200-1400, maybe a bit more for the cell, and likely 2000-2200 for the heater. We recommend that you clean the filter, then run the VSP down until the flow switch for the SWG turns the SWG off. Then add 200...that gives you operating room for a dirty filter.

This site claims it has some of the models. They come up as a top search everytime I look up anything filter related.

I got my Pentair heater through Vita Filter recently and they were great to deal with.

Replacing just the motor with a Nidec Neptune NPTQ165, and new gasket, shaft seal and O rings, and impeller screw, would convert you.

Getting a larger Neptune NPTQ270 and a new impeller 073130 to match would raise the price ~$200 or more.

Regardless of which option you choose, if you are going to DIY, be sure to watch some YouTube videos on replacing a seal or motor in a Whisperflo pump. The important part will be the impeller screw, it is left-hand threaded and must be replaced, before reassembling the pump.

Whatever way you go, using a VSP at lower speeds will save you $$.

I would check the impellor #...as I mentioned before, the motor was changed and I'll bet they didn't change the impeller. # should be molded into the impeller.

Thank you. Seeing the previous owner/pool maintenance company couldn't replace cracked/disolving baskets, you are probably right...and the original impeller is probably still installed. I will definitely try to check it out this week.

No such calculation exists, regardless of what the dealer says. No calculation that holds any water, anyway. (Pun intended).

Environmental debris from your yard is 95% of your filtering needs. Your yard debris determines how big your filter should be. The pool volume that the industry touts is a crock because you could go twice as deep, with twice the gallons, but the surface area that yard crud falls/blows into didn't change, nor did the amount of debris.

Or the line of trees between you and your neighbor all blow towards them. You have the same exact pool and you need very little filtering and they need a ton. So XXX filter for YYYYYY gallons is moot.

An above ground pool collects somewhat less debris because of the raised walls. Leaves for example wont blow across the lawn and into the pool, they'll bounce around it and keep going. Pollen, dust or lighter debris may become airborne a 2nd time and find it's way in.

Post some pics of the yard so we get an idea how much crud yours might have.

This is the existing pool, not the pool we are putting in. The black lines are approximately where the new pool will be.
