Upgrade recommendations for replacing 14" Intex sand filter combo?

[swimdaddy]

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.

The fact that it was OK in the past, is no guarantee it will be now.

Lowes does not stick to a reliable or single source of product. And even brands you might think are OK, are not. I have a "Watts brand" 3/4" x 4" brass threaded nipple,t hat should have lasted 100 years. But Watts has gone from being a US company to a little US stuff and a lot of Chinese stuff. The nipple has a pinhole in the body, between the threads. Naturally, I had put it underground when I replaced my fathers pressure reducing valve . . . so it was a huge mess to repair.

Some Chinese made product is OK, but most of it suffers high rates of defects. That means 90% is OK, but if you are the 1 in 10 that gets the P. o. S., watch out!
