The following information is from Ian Suddaby. Ian states – This very unusual drain was seen near Edinburgh. It’s unusual because it’s made from two U-shaped or horseshoe drains, one upside down in the base and one the right way up on top. This clearly increases the capacity but has its problems. It’s also unusual…
These pencil or whistle drains were found by Ian Suddaby. They were found in 2003 at Longhaven near Peterhead. Cruden Bay Brick and Tile Works was a few miles away but where the pipes were made is unknown.
Although they did not contain water when found in the autumn, the drains appeared to be unblocked. It is thought, that in these very narrow drains, the water flow may thus be faster than in a ‘normal’ sized drain and thus not as prone to blocking with silt etc.
The tiles measure approx 12″ long x 1″ inside diameter and 1 1/2″ outside diameter although all these measurements can vary by a good 1/8″ depending on where you measure.
