PVC piping

[CarlD]

The fittings on the pump and filter are all standard 1.5" fittings, and yes, they do screw on and off. You use teflon tape on the threads.

TigerFlex is probably not available at Lowes, but most pool stores sell it, as do on-line discount houses. I don't know if plumbing supply houses stock it, but they should. I only know that one brand not others.

Thanks for the complement. I like the plumbing to be clean--I re-plumbed it after the installers messed up big-time on the plumbing. It was sloppy as heck and leaked from the get-go. They had used barbed fittings INSIDE the TigerFlex. A lot of pool guys do that but its a no-no. It's very difficult to keep it from leaking--you may need 2 or 3 hose clamps. The glue-on schedule 40 fittings don't leak. So I immediately had to re-plumb the pool. It worked but wasn't as clean as I like so I replumbed the filter connections again.

Here's a pic of my setup. Not as clean but lots of options. The Main Drain and Skimmer have valves, I added unions so I can do repair work as needed (after having to cut the pipe for repairs), and I hard piped my backwash line under ground to a better discharge area. After the filter it goes through the SWC cell and then I have the option of running through the returns, fountain, or both. The controll box on the wall is for the Autopilot.

If I were doing a fresh instal I'd eliminate some of the 90's and lay it out a bit more efficiently, but I inherited the basic setup with the house.
