underground curiosity
 
just curious - what happens if a buried cast iron or PVC pipe develop a leak ? how bad can it be ? if it only leaks, say 1% of the discharge.

i am sure some of the pros have seen this scenario ...

it is not happening to me but was curious since i just buried some drain plumbing ...

Sometimes lines can leak for years before a leak is noticed because the ground will suck it right up. Sometimes you will notice it right away due to clogs caused by a bad break filling the pipe with dirt, etc. Sometimes you notice it right away from a sewage smell or sewage coming up. It really depends on your situation. The solution in any case though is to dig it up and replace the leaking potion.

If the line is relatively straight, I think they can be lined, no?

I never heard of that and it would probably take almost the same amount of work if not more to line it as to replace it.

Relining is piontless on most lines. I prefer to dig it up and replace it 100%

A while back we replaced the drains in an old house that had had a damp basement as long as the occupants could remember. The old cast had several rotted out sections under the concrete. The concrete was old with a clay soil underneath, causing the moisture to wick up through the floor. New pvc, dry floor.
