Clay Sewer Pipe

[Bill Kibbel]

I was just reading the Plumbers Trade Journal from 1917.  In it, the 'Sewer Pipe Manufacturers Association' states, among other virtues:  

"Clay pipe always outlasts the building in which it was installed, in fact it has proved indestructible in thousands of cases".

I would like to show the SPMA those same thousands of buildings now.

Two years ago we trenched and installed 400' of drain tile in our yard. We dug up three different clay tile drainage lines running perpendicular to our trenches. All of them were packed solid with clay soil and sediment. 

My basement floor drain is glazed bell hub clay tile and is clear for over 200'. It's 152 years old.
