Q: hydrualic effects of right-angle bends in PVC water lines
I recently repaired a leak in my water service lateral (1" PVC to 3/4"
copper). The fitting I replaced was hard to reach without digging a LOT more hole. I got the copper-to-PVC adapter in well enough, but it was damned hard to get the PVC pipes into the glued-up slip joint because there wasn't a lot of flex available. I thought afterwards that I could have put a series of right-angle bends in the PVC pipe which would afford a lot more flexibility during the repair. Is there a reason NOT to do this? Would make for stress in the pipe? Any hydraulic effects? THanks a heap, -Zz |

that would be fine, but you could also use a slip type compression fitting.

THanks a heap, -Zz- Hide quoted text - - Show quoted text - PVC Dressler coupling? I wouldn't use one in buried service. I used to irrigate from the creek and used one as the disconnect to remove the pump at the end of the season. That thing coldformed the PVC pipe reducing it in size by at least a 1/4" in a couple years. Of course the effect was probably due to the repeated remove/replace but still... Harry K |

It's the only sensible way to repair. Yeah, and I've had to dig them up and effect a proper repair. Perhaps because of the cold forming of some component, but for whatever reason they never stay 100% water tight. Roots will find their way to those drops of water. The roots force around the gasket and then you have a significant leak. Dresslers are seldom if ever appropriate for buried irrigation service. Use a real repair coupling and proper PVC glue and all will be well. Or if you have to, hollow out a normal coupling to make your own repair coupling. Just don't use a dressler. sdb -- What's seen on your screen? http://PcScreenWatch.com sdbuse1 on mailhost bigfoot.com |

Here is a chart that gives "effective added length" for some typical fittings by pipe size. I was surprised to see that my "rule of thumb" was only moderately accurate for pipes 1" or smaller. Fittings for large pipes add much more "effective length" http://www.plumbingsupply.com/flowchart.html cheers Bob |
