All good comments to date but the pipe could still be ductile iron and fail
in 12 years. If the ground is wet and conducive to corrosion DI can get
holes in it. We have had sections fail in 10 years. DI is ok underground
even in poor (wet) conditions if you polyethylene wrap it per AWWA C105.
Yo
Dave,
You don't need thrust blocking if mechanical restraint is used such as
bolted flanges, grooved couplings, screw threads or even plain end
fittings designed to be installed without other restraint such as Fit
fittings. Unfortunately none of these that I'm aware of work with UG
type ductile of
I can assure you the only thing is was wrapped in was clay and rubble rocks
kicking around the jobsite. Not a stitch of restraining or thrust blocking
at the FDC elbow either. I appreciate the guidance and will be sure to pass
along the final result when they cut and remove the pipe from the tren

Doubt it's ductile... Schedule 10 and Schedule 7 and Schedule 5 are available
in 25 ft lengths - and makes good rusty water too!

C900 PVC with DI fittings is the way to go.

Sounds more like black carbon steel. DI should last for a lot longer than 12
years. Never seen it deteriorate with pin holes, but have seen CS do that,
especially direct bury.
I checked one mfgr and they list 4" DI as coming in 18ft lengths.
Just because the check is a DI valve has nothing to

The metal label on the valve says 'FireLock S/717 Ductile Iron 250 PSI'.
Nothing altered or unusual about the valve's metal tag, the length of pipe
is what got me scratching my head.

It doesn't sound like DI to me. I have seen it used for UG going to an FDC
piping under a gravel drive with heavy traffic. I surely haven't seen DI in
24'-0 lengths or DI having holes as you described. Sounds more like black
steel that has deteriorated as it would in one of those nightmare dry

I have never personally seen Ductile Iron with pinholes.
I have also never seen DI in 24' lengths.
That doesn't mean either are impossible.
Does the "250 psi Ductile Iron" look spray painted?
