Charlotte Pipe vs. Silverline, Any Difference in Quality / Reducing Fitting Question also

[ksquared]

I ordered Charlotte Pipe from Lowe's. I got Silverline Pipe. Should I be upset? Is it worth returning? Are all Schedule 40 pipes manufactured to the same standards?

I'm also needing the reducing fitting, to go from 3" to 2" for the Pentair 263080 valve. I have found Charlotte 437-338, which appears to be what is needed. The question is, do I try to get a bit of 3" pipe so I don't permanently attach this reducing fitting to the actual valve? Or is it the situation that once it is installed, that valve will be staying here for the rest of its life?

Thanks for all the help! I am making some progress, couldn't do it without everybody here!!

Not all SCH 40 PVC is the same. Key words to look for are "pressure applications" vs. "drain/waste/vent (DWV)". The Silverline pipes are carry the ASTM D 1785 rating which is the standard for pressure rated pipe. No worries there.

I think a photo may help us understand the question.

For the valve, the three places needing fittings to attach to the pool plumbing (inlet, pool, waste) are 3", while the pool plumbing is 2". I have found the Charlotte 437-338 bushing 3" to 2". There also seemed to be other bushings that weren't suitable for pressure, but from my research this one is acceptable.
So the choice is to glue the busing directly to the valve, thus permanently altering the valve from 3" to 2", or attempting to get some 3" schedule 40 pipe to have a short bit attached to the valve, then the bushing in the pipe, thus not permanently altering the valve.


Thanks.

According to the instructions for that valve, it accepts either 2 1/2" PVC pipe (inside the fitting) or 3" fittings (coupler or elbow) directly to the valve. You could use a 2 1/2" reducer bushing.

I think the real crux of your question is whether to do the adapting right on the valve or to have a 3" stub. The answer is that it depends on your plumbing layout and space available. I wouldn't worry about trying to "preserve" the valve. Just be sure of your plumbing before you commit to it. You'll be gluing something to it one way or another. You could even put a union on it, if you're comfortable with that.
