You replace it with PVC drain pipe, 4" in diameter, it comes with holes
punched in it for drainage. You do NOT cut it lengthwise but put a whole
piece of pipe in the ground. Where it abuts the old clay pipes, cover the
joint with some tar paper or a short length of pipe that is split into a
halfround to keep particulates from dropping down.

Hi,
I have a septic system that was put in when the house was built in the
60's. I have determined that several feet of drain field concrete tile
have disintegrated in one channel, and I would like to replace them. I
have already dug a ditch and exposed the problem area, and only need to
replace about 4-5 feet of it.

Can anyone suggest what material should be used to replace? One local
gentleman suggested plastic piping from the local hardware store, but
that I may need to cut it myself. I'm not sure if I understood 100%,
but I think he's just talking about some ABS plastic and cutting it
into half-cylinders myself.

As much fun as digging the ditch was, I would prefer to not do it again
any time soon.
Can anyone suggest if such an approach would be a good solution, or if
not can you recommend what kind of supplier to pursue these replacement
tiles from?

The area surrounding the pipes is currently a mixture of dirt and
gravel. I expected to find just gravel, but probably this has migrated
around over the last 40 years. I assume I should resurround this bit of
pipe with fresh gravel while I'm in here. Any suggestion on what size
to use, how wide of a channel to fill with it, or other relevant
specifications?

Thanks much!
