Okay guys,,,put your thinking caps on. My main sprinkler line from my
pump to my irrigation system broke. It is a 2" PVC line...The problem
is this...there is no way to replace the broken line because I can not
bend the pipe in order to slide the fittings together. I have tried
the rubber type flexible pipe and with the pressure it pops off. I am
wondering if anyone has any ideas or can I create a 4x90degree in
order to create proper connections. Will the 90 degree angles handle
This is the 2nd time in a week that I find myself asking "WHY??" to a
post suggesting a PVC union. The only practical use of a union would
be an instance where you would want to take it apart repeatedly.
Follow Rico's advice and use a repair coupling or two and the
appropriate glue. You should be able to buy 2 repair couplings and a
5' section of pipe for less than the cost of the union.
While I would probably not go the 'union' route, there is nothing
wrong with one. They are just as permanent a fitting as a normal
joint. YOu apparently have never tried to splice in fittings in a 2"
pvc pipe. It would take a _lot_ of digging to get enough wriggle room
to do it. Granted it is one of the right ways to do it but there are
simpler work arounds (4 90s or 4 45s for one, a union for another).
In this case, you could probably cut a 3" section of pipe out, and use
two couplings and a slightly shorter pc of 2" pipe to make the
repair. You would have to do no more digging than you would to try to
get your 4 elbows solution in place.
No one is suggesting that you try to dig up enough pipe to flex the
pipe around to get a single coupling in place. That might take lots
You would still need some 'flex' room. You are talking about
inserting about a 6" section of pipe into a rigid pipe. Each of those
fitting requir sliding a piece of pipe into the fitting. 4 90s, or 4
45s, plus a short piece of pipe can be 'turned' into place for the
final join with a bit of force. I have done it 3 times now on 1"
pipe, haven't tried it on larger sizes.
Yes, the 4 '90's solution is doable. I have used it myself. Does
cause a bit of piping friction loss in efficiency.
Don't try the "Dressler" or "Dresser" couplings on PVC. They are the
ones with two compression fittings and rubber gaskets. I used one as
a quick disconnect on a sprinkler system feeding out of a stream.
Over time it actually deformed the PVC by squeezing it down to a
lesser diameter. I wouldn't use one ever in a buried pipe.
You need to go to an irrigation or sprinkler place. Most plumbing
supply houses do not carry these. Call around and ask for a
telescoping pvc repair coupling. We use these on full pressure
potable systems and sprinkler. They are great when a trencher
has chewed the line, they also work great if one backhoe tooth
hurt the pipe (full bucket takes out too much pipe).
Here is an example from KBI
