Sometimes I don't know whether to post in "construction" or "DIY," or "DUMMIES FOR NEWBIES!"
_____________________________________________________________________________
Can you guys help me out? I'm always running across an issue or 2 when I play around with PVC pipe, and I wonder how other folks [or even professionals] deal with things:
1) FOR LARGER DIAMETER PIPE, for example, 4" thin-wall for sewer & drainage is what I'm using now -- It's the kind that is slightly flared at one end, and there are special fittings to use with it [standard fittings won't work, on either end], BUT I run across these same problems with any of the larger diameter pipes -- so it's not just with this particular pipe.
2) CONFUSION ABOUT WATER-TIGHTNESS & SEALING: This is the pipe I'll be using to carry water from my turtle bog back into the pond. I got it because it was light-weight [compared to sch 40 pipe] and cheaper than sch 40. The salesman said that it might not be water-tite for a "pond application," so I figured I could apply a bead of silicon sealant -- it's not going to be underwater, just a water conduit.
Right now I have my pieces laid out and sort of pushed together [doing the best that I could], and there is some leakage.
The salesman also said you could use standard PVC solvent cements with it, but 1) how does that work if I can't even get the tubing inside the fitting, and 2) would using a solvent weld mean that I would or would not still have a water-titeness issue? IOW, would the solvent weld act to "seam" the pipe shut against leakage? In that case, the silicon wouldn't be necessary, right?
But back to #1, if the stuff is so darn hard to insert, how in the heck can there be leakage?
Please help me get this conduit put together......I can't move on until this is completed!

- I can't get a good "seat" into a fitting -- I can wiggle it, twist it, pound it......but it just doesn't want to go in -- I might get it in 1/4 of the way........
- and it's even worse when I have longer lengths, 'cause I can't get the right kind of grip, or traction, or whatever -- holding the fitting at one end and trying to insert the unwieldy pipe.....!
- and then it will be crooked......
- and it's the thin-wall stuff that's always the worse (and that's with any size)
- then, to repeat the above, when I get one pipe into the fitting, it's even WORSE when it's time to attach pipe to the other end of the fitting!
- and then, I can't twist the pipe inside the fitting if I need to make an adjustment
