Upgrade recommendations for replacing 14" Intex sand filter combo?

[Pappy]

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.

What is the best way to connect the hard piping to the pool wall fittings? Since the walls flex and move a considerable distance, there needs to be a flexible connection. I think 1-1/2" reinforced vinyl tubing is what I need, but I'm not sure.

Would this work? https://www.lowes.com/pd/EASTMAN-1-1...ose/1000365073

I'd look at this:
1.5" ID 70 psi Braided Flexible Chemical Resistant PVC Tubing
instead.

Flex PVC, like you found at Lowes varies a lot in quality, and I have never discovered how to tell the good stuff (rare) from the junk (common). The typical stuff, which I've purchased from SCP wholesale supply, gets pinholes after a year or so.

The reinforced flex is made for insert fittings and clamps, but can be glued if you are very careful. It tends to not maintain a perfectly round cross-section, so you have to be careful when you insert it.

Maybe you and Brokk can work out a 'works-for-everybody' method of plumbing to Intex-type pools?

1.5" ID 70 psi Braided Flexible Chemical Resistant PVC Tubing

Is exactly what I had in mind. I was unaware that it could successfully be glued. That's why I asked about the other stuff. Is it glued to a pvc hose barb or into a standard pvc slip fitting?

'works-for-everybody' method of plumbing to Intex-type pools?

,,, probably doesn't exist, but 'works-for handyfolk' is completely do-able. I full well intend to take lots of pictures and explain my processes and the thoughts behind them.

If you put it on a barbed fitting, use clamps.

If you glue it, just make sure that it fits in snugly and that you hold it in place for 90 seconds or more. Otherwise it will 'ooch' out. Also, a small bit before depending on it. I've glued it, but formulations vary and you want to make sure the tube YOU get will glue OK.

I have an "intex type" pool, a Splash super pool.

I have used the flex PVC that Pappy posted and it has worked well for 3 years without leaks...... yet. I'll watch for pinholes. I used barbed fittings with clamps and quick connect fittings everywhere I can think of (once you push the barbed fitting into the flex PVC, you'll never get it out again), they make it easy to take things apart for servicing or storage. I also use ball valves that come apart for servicing and use them as quick connections too.

Ever fitting and line I have used has come from Lowe's, except for the wall fittings. No leaks, no issues.

Perhaps I can make an inner ferrule to help hold it round, similar to the insert in air brake compression fittings. I'd rather use the clear pvc if the quality is as good or better.

[Pappy]

The price isn't too much different, so I probably will. They recommend the black pipe, instead of white, if it will be exposed to the sun. It can be painted or wrapped (guess who sells wrap tape) to protect it from UV energy.

The pump came in today. Looks like an open box return, rather than "used: like new". There is no sign that it has ever been wired or plumbed. I'm going to post pictures showing the difference in the Intex .75 hp rated pump/motor and the Pentair .75 hp rated pump/motor. The Intex is rated at 120 V - 4.8 A MAX. The Pentair is rated at 120 V 4.7 A - - - on LOW. 14.6 A full load.

While I was looking for a schedule 80 pvc supplier, I stumbled upon these people.

https://flexpvc.com/

They sell domestic flex pvc in several sizes by the foot or in rolls - with a lifetime limited warranty? Been in business since February, 2008. One BBB complaint. No BBB reviews. Not BBB accredited.

Hmmmmm.
