Over-Crimped PEX! How bad?

I just bought a new 3/4" PEX crimper, and made two mistakes installing a 110' run from the meter to the house: 1) I didn't use continuous (coiled) pipe, but rather used 20' sticks, so there are 5 unnecessary couplings buried in the trench, 2) I didn't pay close enough attention to what I was doing, and accidentally misused my go/no-go gauge and adjusted my crimper to allow fittings to just barely fit into the "NO-GO" slot instead of the "go" slot, so all my fittings are over-crimped.

I buried everything before I realized the crimper adjustment mistake.

How much trouble am I in? What it the realistic likelihood of failure for these over-crimped fittings?

I REALLY don't want to dig up the 100+-foot trench again! ...and I sure do wish I'd used a continuous run of coiled pipe so that this wouldn't have even been an issue...

Thanks for any help/insight...

What is a "no-go" and "go" slot? The crimpers we use only have one setting per size.

Anyway, dig up the farthest end of the pipe from the house, drain and cap the line, and put a compressor on it. Use at least 100 psi. See if it holds for 24 hours. If it does, you should be fine.

How to Use Pex Go-Nogo Gauge

By Kelly Nuttall, eHow Contributor

The PEX plumbing system is an innovative way of installing plumbing in residential and commercial applications. A combination of PEX fittings, crimp rings, PEX tubing and a PEX crimping tool are required during an installation. A Go/No-Go gauge is included with every crimping tool sold. It is a flat piece of metal with a few cut-outs on each side. One side is the "Go" side; the other side is the "No-Go" side. Use both sides to see if you crimped each fitting into place correctly.

Instructions

Place a crimp ring over the PEX tubing and insert a PEX fitting. Slide the crimp ring so it is 1/8-inch from the end of the tubing right next to the PEX fitting.

Use a PEX crimper to crimp the ring into place over the PEX tubing.

Slide the "Go" side of the gauge over the crimped ring. If the crimp was made correctly, the gauge will pass over the ring with not problems.

Turn the gauge over and try to pass the "No-Go" side of the gauge over the crimp ring. The crimp ring should be unable to enter the gauge at any point on the "No-Go" side of the gauge.

Cut the PEX fitting out and replace it with a new crimp ring and fitting if the crimp ring fails either test.

Ok, I'm sure the OP will never be back because this thread is ancient, so I won't address that. I am just kind of worried that a plumber doesn't use a go/no-go.

Thanks for the post, havasu. I didn't know this was the name...we call it "calibration gauge". At first I thought OP was talking about those crimps that work with a pair of pliers...thanks for clearing this up.
